The SKKD380/22H4 is a SEMIKRON three-phase diode bridge rectifier module rated for 380A average output current and a repetitive peak reverse voltage of 2200V. Housed in a SEMIKRON SKKD-series power package with an isolated baseplate, this module is engineered for high-reliability DC bus generation in industrial power electronics. Its robust silicon diode construction and optimized thermal interface make it a preferred choice where high junction temperatures, continuous duty cycles, and demanding transient conditions are everyday realities.

The SKKD380/22H4 is widely deployed in AC drives, soft starters, UPS systems, industrial welding equipment, crane and hoist drives, and large DC motor control systems. It is equally at home in wind and solar power conditioning stages that require stable, high-voltage DC bus rectification. Any application requiring rugged three-phase full-wave rectification at high current levels—particularly where voltage stresses exceed the capabilities of lower-rated modules—is a strong candidate for this SEMIKRON bridge module.

Key Features of the SKKD380/22H4:

• 2200V repetitive peak reverse voltage (V_RRM) rating provides robust voltage margin for high-line and transient-rich industrial environments
• 380A average rectified output current supports continuous full-load operation in high-power three-phase rectifier stages
• Isolated copper baseplate construction enables direct mounting to heatsinks without additional isolation hardware, simplifying thermal stack design
• SEMIKRON SKKD-series package offers standardized bolt-down mounting with industry-proven pressure contact technology for low thermal resistance (R_th(j-c))
• Optimized diode chip geometry minimizes forward voltage drop (V_F), reducing conduction losses and heatsink sizing requirements
• Compatible with standard SEMIKRON SKKD footprint, allowing drop-in replacement in existing drive and rectifier designs without mechanical modifications

With a factory lead time currently exceeding 99 weeks from SEMIKRON's production schedule, the SKKD380/22H4 presents a serious procurement challenge for maintenance teams facing unplanned equipment downtime and for OEMs managing production continuity. ATI Accurate Technology maintains active sourcing networks for exactly these situations—long lead time, allocated, and hard-to-find SEMIKRON power modules.
