ND431621 Powerex - Thyristor / Diode Module

ND431621 Description

The ND431621 from Infineon Technologies is a dual diode module (POW-R-BLOK). Typical applications include soft starters, AC power controllers, controlled rectifiers, DC motor drives and heating control. Many of these parts are still in service in machines built years ago, and a direct replacement is often the fastest way to get one running again.

USComponent has sourced power semiconductors for maintenance teams and OEMs since 2001. For price and availability of the ND431621, send us a request for quote. Please confirm the specifications against the manufacturer's datasheet before purchase.
