Soft switching with our Soft Recovery Freewheeling Diodes

4500 V / 6500 V diode disc series for IGCTs & presspack IGBTs (PPI)

Our soft recovery diode disc series consists of robust and powerful disc device types developed for the special requirements of medium-voltage IGCT inverter applications. All devices are designed for high surge current capability. For IGCT inverter applications in particular, they are optimized to achieve excellent soft recovery behavior even under the most demanding turn-off conditions. High-tech production processes deliver outstanding dynamic parameters for best-cost designs with extreme soft recovery behavior to avoid overvoltage at the IGCT device.

- Extreme soft switching behavior and low on-state losses in one device
- Low inductive connection to IGCT/presspack IGBT possible
