Product Description

Product Overview

Vishay Semiconductors' Hockey-PUK devices are high-performance diodes and thyristors featuring metal cases with ceramic insulators and international standard case options. These devices are designed for low-thermal-resistance packages where the silicon die contact is achieved through externally applied pressure from a clamp system. They are suitable for applications requiring double-sided cooling (DSC) for maximum current capability, or single-sided cooling (SSC). Proper mounting is crucial to ensure optimal electrical and thermal contact, utilizing specific clamping forces and heatsink preparation.
