TZ425N14KOF Infineon - SCR
Discontinued: Infineon recommended replacement: TZ425N16KOF. We supply both the original TZ425N14KOF and the replacement - check the datasheets before switching.
TZ425N14KOF Description
The TZ425N14KOF is a thyristor module made by Infineon Technologies (formerly Eupec). Typical applications include soft starters, AC power controllers, controlled rectifiers, DC motor drives and heating control. If you are repairing older equipment, we can usually find this exact part, including date codes that are no longer in production.
USComponent (Young & New Century LLC) supplies power modules, thyristors, diodes and other industrial components, including legacy parts. Contact us for a quote on the TZ425N14KOF, and please confirm ratings against the datasheet before ordering.
Target Applications
Infineon TZ425N14KOF 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.
