TT250N18 Description

The Infineon Technologies (formerly Eupec) TT250N18 is a thyristor module, rated for 1800 V and 250 A. Common uses are AC switches, soft starters, DC drives and controlled rectifiers in industrial power equipment. Production of many older modules has ended, but we keep sourcing them for repair and maintenance customers.
