About

Introduction to the IGCT and IGBT freewheeling diodes

Our diodes have an excellent soft recovery behavior even under the most demanding turn-off conditions to avoid overvoltage at the switching device. Our high-tech production processes deliver outstanding dynamic parameters for the best cost and longest lifetime.

Benefits for medium voltage IGCT inverters

The major benefits of freewheeling and clamping diodes for medium voltage IGCT inverters, marked as SH-diodes, are the soft-switching behavior optimized for IGCT devices and the current turn-off capability up to 5 kA/µs which leads to optimized system performance.

Benefits for medium-voltage press pack IGBT inverter

The major benefits of freewheeling and clamping diodes for medium-voltage press pack IGBT inverters, marked as U-diodes, are the soft-switching behavior optimized for IGCT or IGBT devices with a current turn-off capability up to 5 kA/µs and less snubber effort.
