The SEMIKRON SKKD260/22H4 is a three-phase diode bridge rectifier module engineered for high-power industrial conversion applications requiring sustained 260A average output current at up to 2200V repetitive peak reverse voltage. Built to SEMIKRON's SKKD series standards, this module integrates a full bridge rectifier topology in a compact, industry-standard housing with isolated baseplate construction, enabling direct heatsink mounting and simplified thermal management. It is a proven solution where reliable, efficient AC-to-DC rectification is critical to system uptime and performance.

The SKKD260/22H4 is well suited for front-end rectifier stages in medium-voltage variable frequency drives (VFDs), regenerative braking systems, industrial UPS and battery charger platforms, welding equipment power supplies, and crane and hoist drive systems. Its high voltage rating makes it particularly appropriate for 690VAC three-phase input applications and other demanding grid-connected environments where transient overvoltage tolerance is essential. Engineers specifying rectifier modules for heavy industrial machinery will find the SKKD260/22H4 a reliable, field-proven component.
