Working Principle

The working principle of the AS4PKHM3_A/H rectifier is based on the PN junction theory. When a voltage is applied across the rectifier, a current flows through the device. When the applied voltage is higher than the PN junction\'s threshold, a reverse breakdown occurs, allowing current to flow in the opposite direction.This type of rectifier has a low forward voltage drop. This means that very little of the input power is dissipated as heat. By reducing the amount of power dissipated, a rectifier is able to reduce cooling requirements, consequently reducing the device\'s overall cost.In addition, the AS4PKHM3_A/H rectifier has a very low reverse recovery time. This ensures that the device can respond to voltage changes quickly and accurately without any significant loss of power.
