Working Principle

The V20PW15CHM3/I is a bridge rectifier composed of four discrete diodes arranged so that alternate diode/diode pairs can be connected together in parallel. The rectifier works by operating in a reverse-bias mode. It is a unidirectional device that allows electrical current to flow in one direction only, from positive to negative. This means that when a positive voltage is applied to the anode, current will immediately flow from the anode to the cathode. When the voltage is reversed, the diode will block current, as the negative voltage applied to the anode will be stronger than the positive voltage applied to the cathode. This process helps to regulate the flow of current in an AC circuit.

The V20PW15CHM3/I has an ultra-fast reverse recovery time of less than 20ns. This quick recovery time means that it is able to recover quickly after a reverse current, which helps reduce switching losses and improve efficiency. The device also offers excellent di/dt immunity which helps reduce EMI and meet EMI requirements.

Conclusion

The V20PW15CHM3/I is a high surge single-phase bridge rectifier from Vishay. It is available in a TO-220 package and can be used for a wide range of applications, from PC power supplies, LED lighting and industrial motor controls to home appliance power supplies.
