• Industrial Electronics: Such as electric welding machine, motor driver, UPS and so on.
• Consumer Electronics: Such as mobile phones, digital cameras, sport cameras and so on.

Working Principle

The AS3PDHM3_A/H rectifier diode functions by allowing electric current flow in one direction but not the other. The forward current is called forward bias while the reverse current is known as reverse bias. When the bias voltage applied to the diode is above the device’s breakdown voltage, the diode is cut off and no current flows through it. But when bias voltage is below breakdown voltage, a forward current passes through the diode.

In addition, when reverse bias is greater than the breakdown voltage, the diode starts to conduct, thus it can be used to protect components from overvoltage. This is usually known as avalanche voltage.

Furthermore, AS3PDHM3_A/H rectifier diodes also feature low reverse leakage current enabling the device to be used in a variety of power supply circuits. The low reverse leakage current is mainly due to the high dielectric leakage insulation of the diode.

Summary

To summarize, AS3PDHM3_A/H rectifier diodes are used in a wide variety of applications such as computers, communications, automotive electronics, industrial electronics, and consumer electronics. They feature low reverse leakage current and high surge capability and can be used as a protection against overvoltage. The diode functions by allowing electrical current to pass in one direction but not the other. Low reverse leakage current is mainly due to the high dielectric leakage insulation of the diode.
