HFA240NJ40C Description

Short technical summary and product information.

The HFA240NJ40C is a high-performance fast recovery diode module from Vishay's HEXFRED series. It is designed for applications requiring low switching losses and reduced EMI/RFI. The module contains two diodes in a common cathode configuration with a maximum reverse voltage of 400V and average forward current of 244A per leg at 25°C. The typical forward voltage is 1.1V at 120A and 25°C. The reverse recovery time is typically 50ns, with soft recovery characteristics that reduce the need for snubbing. The module is housed in a TO-244AB package with lug terminals for chassis mounting. It is suitable for use in power converters, motor drives, and other high-frequency power conditioning systems.
