DF75BA80SanRex - Diode Module

DF75BA80 Description

DF75BA80 is a high-power bridge rectifier diode designed for use in power electronics applications, such as power supplies, motor drives, and welding equipment. The diode is manufactured by SanRex Corporation and has the following specifications: Maximum repetitive reverse voltage (Vrrm): 800V Maximum forward current (If): 75A Maximum surge current: 500A Maximum power dissipation (Pd): 600W Low forward voltage drop and high thermal cycling capability High surge capability and short-circuit withstand time The bridge rectifier is a type of diode configuration that converts AC voltage to DC voltage. It consists of four diodes arranged in a bridge configuration, and it is commonly used in power supplies to provide a DC voltage output.

Target Applications

SanRex DF75BA80 is used for AC DC Motor Drive/AVR/Switching －for three phase rectification.
