T4021N52TS02 Infineon - SCR

T4021N52TS02 Description

The T4021N52TS02 from Infineon Technologies is a thyristor (SCR) with a 5200 V / 4021 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.
