SEMIKRON SKKT 570/16E Thyristor Module 1.6KV 156A

From the shop's description

SEMIKRON SKKT 570/16E Thyristor Module 1.6KV 156A The SEMIKRON SKKT 570/16 E is a robust, high-power thyristor module designed for demanding industrial control applications. Packaged in the compact SEMIPACK® 5 format, it integrates dual thyristor chips on an aluminium nitride ceramic-insulated metal baseplate, ensuring excellent thermal conductivity and electrical isolation. Each thyristor features a precious-metal pressure contact system for superior long-term reliability and an amplifying gate structure that delivers precise, low-noise triggering and repeatable switching performance. With a compact footprint and low thermal resistance from junction to case, the module offers efficient heat transfer to heatsinks, simplifying system design and reducing cooling requirements. Rated for a repetitive peak reverse voltage of 1 600 V and average on-state currents up to 570 A (at Tc = 85 °C), it supports a wide range of AC and DC motor drives, soft starters, and power conversion systems. The module’s mechanical design includes standardized M6 and M10 mounting interfaces for straightforward heatsink attachment, while its UL recognition underscores compliance with stringent safety standards. Built to withstand high surge currents and voltage transients, the SKKT 570/16 E provides a durable, high-performance solution for modern power electronics. Features: Heat transfer through aluminium nitride ceramic-isolated metal baseplate. Precious-metal pressure contacts for high reliability. Thyristor with amplifying gate for precise triggering.
