ND431421 Powerex - Thyristor / Diode Module

ND431421 Description

Infineon Technologies (formerly Eupec) makes the ND431421, a dual diode module (POW-R-BLOK). You'll find thyristors like this in soft starters, static switches, DC motor controllers and heater controls. Production of many older modules has ended, but we keep sourcing them for repair and maintenance customers.

We help engineers and repair technicians find parts like the ND431421, including obsolete ones. Send a quick RFQ for current pricing and delivery. Before ordering, please confirm ratings and pin-out with the official datasheet.
