Vishay VS-VSK.170-16 MAGN-A-PAK Thyristor Power Module – 1600V 170A – Reclaimed Part

Vishay — VS-VSK.170-16 MAGN-A-PAK Thyristor Power Module

What It Is

The Vishay VS-VSK.170-16 is a high-voltage, high-current thyristor power module from Vishay’s MAGN-A-PAK family. Designed for industrial power-control applications, it combines high surge-current capability, an electrically isolated baseplate, and rugged screw-terminal construction in a compact module package.

Depending on the exact ordering configuration, the VSK.170 family is available as SCR/SCR or SCR/Diode. The electrically isolated baseplate allows multiple modules to share a common heatsink while simplifying mechanical assembly and thermal management.

Typical applications include UPS systems, industrial motor drives, battery chargers, welding equipment, controlled rectifiers, and high-power AC/DC conversion systems.

Technical Specifications

Why the High Surge Rating Matters

Power-conversion equipment can experience extremely high short-duration currents during capacitor charging, motor startup, transformer energization, or fault events. The VSK.170 series provides more than 5 kA of one-cycle surge capability, giving it substantial short-duration current headroom beyond its normal operating current.
