TT425N08 Description

Infineon Technologies (formerly Eupec) TT425N08 is a thyristor module rated at 800 V. 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. Send us an RFQ for the TT425N08 and we will reply with price, condition and lead time. Please check the manufacturer's datasheet to confirm ratings, package and pin-out before you order.

Target Applications

Infineon TT425N08 is used for AC/DC power conversion and control: controlled and uncontrolled rectifiers, DC motor drives, soft starters, battery chargers, welding equipment, heater and temperature control, and AC power controllers.
