IRKTF81-04HL International Rectifier - MOSFET Module

IRKTF81-04HL Description

The IRKTF81-04HL from International Rectifier is a thyristor module with a 400 V / 180 A rating. It is used in phase-controlled rectifiers, soft starters, battery chargers and temperature controllers for furnaces and heaters. 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 been supplying power semiconductors since 2001, including discontinued and hard-to-find part numbers.
