TT61N08KOF Infineon - SCR Module
Discontinued: Infineon recommended replacement: TT61N12KOF. We supply both the original TT61N08KOF and the replacement - check the datasheets before switching.
TT61N08KOF Description
The TT61N08KOF is a thyristor module made by Infineon Technologies (formerly Eupec). 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.
USComponent has sourced power semiconductors for maintenance teams and OEMs since 2001. For price and availability of the TT61N08KOF, send us a request for quote. Please confirm the specifications against the manufacturer's datasheet before purchase.
Target Applications
Infineon TT61N08KOF 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.
