Ⅲ.Working principle of MUR1560G

MUR1560G is a high-speed rectifier diode whose working principle is based on the unidirectional conductivity of PN junction. The PN junction is an interface formed between a P-type semiconductor and an N-type semiconductor. It has unidirectional conductivity, that is, it only allows current to flow from the P region to the N region, but does not allow current to flow from the N region to the P region.

When the positive electrode (P area) of MUR1560G is connected to a high potential and the negative electrode (N area) is connected to a low potential, the PN junction is in a forward biased state. At this time, the internal electric field in the PN junction is weakened, and most carriers (electrons and holes) hole) can pass through the PN junction smoothly, forming a forward current. Because the MUR1560G has low forward voltage drop, it can rectify the positive half-cycle in the AC signal into pulsating DC when forward biased.

On the contrary, when the positive electrode of MUR1560G is connected to low potential and the negative electrode is connected to high potential, the PN junction is in a reverse biased state. At this time, the internal electric field in the PN junction is enhanced, preventing most carriers from passing through, and only allowing a small amount of reverse leakage current to pass through the PN junction. Since the MUR1560G has a high maximum reverse voltage capability, it can withstand higher voltages in the reverse biased state without breakdown.

The high-speed response characteristics of MUR1560G enable it to quickly switch conductive states during the rectification process and reduce energy loss. In addition, its high temperature stability and low forward voltage drop also make it excellent in applications such as power supplies, inverters, and motor drives.

Ⅵ.Electrical characteristics of MUR1560G

1.Forward conduction voltage (VF): Under normal operating conditions, the forward conduction voltage of MUR1560G is low, generally between 0.8V and 1.3V.

2.Maximum forward continuous current (IF): refers to the maximum current that the diode can continuously conduct under specified working conditions. The exact value also depends on the operating conditions, but usually ranges from a few amps to tens of amps.

3.Reverse breakdown voltage (VR): The reverse breakdown voltage of MUR1560G is relatively high, usually above 100V, which makes it have good reverse voltage tolerance.

4.Recovery time (Trr): This refers to the time required for the internal charge and electric field of the diode to recover to the point where the diode can withstand the reverse voltage again without breakdown after switching from the forward conducting state to the reverse blocking state. . The shorter the recovery time, the better the diode will perform in high frequency applications. For high-speed rectifier diodes such as MUR1560G, their recovery time is usually short and they are suitable for high-frequency rectification circuits.

5.Reverse recovery charge (Qrr): When the diode switches from the forward conducting state to the reverse blocking state, some charge will accumulate near the PN junction. These charges need to be removed during the recovery time to restore the diode's reverse blocking capability. Reverse recovery charge describes the amount of charge involved in this process. A smaller reverse recovery charge means less electromagnetic interference (EMI) generated during the switching process, which is beneficial to improving circuit stability.

Ⅶ.Application fields of MUR1560G

1.Electronic ballast: In electronic ballasts, MUR1560G can be used as a rectifier diode to convert alternating current into direct current and provide reverse voltage protection to protect the ballast circuit. An electronic ballast is a device used to control gas discharge lamps such as fluorescent lamps. Compared with traditional inductive ballasts, electronic ballasts have higher energy efficiency, smaller size and better dimming performance. In electronic ballasts, MUR1560G mainly plays the following roles:

•Voltage limiting: When excessive reverse voltage occurs in the circuit, the high reverse breakdown voltage characteristics of MUR1560G can protect the circuit from damage. It can withstand a certain reverse voltage without conducting, thereby limiting the voltage amplitude in the circuit.

•Rectification: Convert alternating current (AC) into pulsating direct current (DC). This is achieved through the unidirectional conductivity of the diode. When the positive half cycle of the alternating current arrives, the diode is turned on and the current passes; when the negative half cycle arrives, the diode is turned off and the current is cut off. In this way, alternating current is converted into pulsating direct current.

•Protect circuit: Because MUR1560G has fast recovery capabilities, it can quickly clear accumulated charges in the circuit, reducing electromagnetic interference (EMI) and protecting the circuit from damage. In addition, it can withstand certain surge currents and overvoltages, increasing the reliability of the circuit.

•Improved energy efficiency: Since MUR1560G has characteristics such as low forward voltage drop and low reverse leakage current, it generates less heat during the rectification process, thus improving the energy efficiency of the entire electronic ballast.

By adjusting the on and off states of the diode, the current and voltage of the motor can be controlled, thereby achieving precise control of the motor. In motor control, a common method is to use power electronic switches (such as transistors, MOSFETs or IGBTs) to control the current and voltage of the motor to achieve precise control of the motor.

The MUR1560G's ultra-fast recovery time (trr) and low reverse recovery charge (Qrr) help reduce additional losses during switching, thereby improving overall power efficiency.

•Withstand high voltages and currents: Switching power supplies often need to handle higher voltages and currents, which requires the diodes used to have excellent electrical performance. MUR1560G can withstand high reverse voltage and high forward current, making it very suitable for high-voltage and high-current applications such as switching power supplies.

•Increase power supply stability: In switching power supplies, fast and stable power conversion is crucial to maintain the stability of the output voltage. The ultra-fast recovery characteristics of MUR1560G ensure that the diode can quickly return to normal working status when the power switch is quickly switched, thereby reducing voltage fluctuations and noise and increasing the stability of the power supply.

4.Power supply protection: MUR1560G can be used in power supply protection circuits as reverse protection diodes to prevent reverse voltage at the power input end from damaging the circuit. MUR1560G is a high-efficiency, fast-recovery diode with excellent reverse voltage withstand capability. When a reverse voltage appears at the power input, the MUR1560G will quickly turn on and guide the reverse voltage to the ground, thereby protecting other components in the circuit from damage. This protection mechanism can effectively prevent equipment failure due to reverse voltage and improve the stability and reliability of the power system.

5.Motor driver: In the motor driver, MUR1560G can be used as a reverse voltage protection diode to prevent the reverse voltage generated when the motor is running from damaging the driver circuit.

MUR1560G also provides reverse voltage protection. In the LED lighting system, if reverse voltage appears on the LED driver due to some reasons (such as power supply polarity reversal, external interference, etc.), the MUR1560G will quickly turn on and guide the reverse voltage to the ground, thereby protecting LED driver circuit is protected from damage.
