Semikron – SKKT 162/16E – Thyristor SCR Power Module – 1600V 156A – Reclaimed Part

Semikron — SKKT 162/16E Thyristor SCR Power Module 1600 V • 156 A I_T(AV) • Dual Thyristor-Thyristor Configuration • Isolated Baseplate • SEMIPACK 2

What it is

The Semikron SKKT 162/16E is an industrial-grade 1600 V, 156 A dual thyristor/SCR power module housed in the proven SEMIPACK 2 package. Its thyristor-thyristor configuration is designed for high-power controlled rectification and phase-control applications requiring high current capability, reliable triggering and robust thermal performance.

The module uses a ceramic-isolated metal baseplate for efficient heat transfer and straightforward heatsink mounting. With a 5000 A surge-current rating and 125 kA²s I²t capability, the SKKT 162/16E is suited to industrial motor controls, rectifiers, soft starters, heater and temperature controls, professional lighting systems and other demanding power-control applications.
