The SEMIKRON SKD 25/16 is a three-phase diode bridge rectifier module combining six diodes in a single isolated package, delivering 25A continuous output current at a 1600V repetitive peak reverse voltage rating. The SKD platform features a low-inductance internal layout and an insulated copper base for direct heatsink mounting, minimizing thermal resistance and simplifying system integration. This module is engineered for demanding industrial environments where voltage transients, thermal cycling, and continuous duty operation require a rectifier solution built to tight tolerance specifications and consistent lot-to-lot quality.

The SKD 25/16 is widely specified in variable-speed AC and DC motor drives, industrial power supplies, UPS systems, welding equipment, and field excitation circuits for synchronous machines. Its 1600V voltage class provides the derating margin required in 690VAC mains-connected applications or systems with significant line-side inductance and transient overvoltages. OEM machine builders and MRO maintenance teams select this module for soft-starter front ends, crane and hoist drive input stages, and controlled rectifier front ends where proven three-phase rectification reliability is non-negotiable.

Quick Reference: SKD 25/16

Key Features of the SKD 25/16:

• Three-phase full-wave bridge configuration — six diodes internally connected for direct three-phase rectification without external wiring
• 1600V V_RRM rating — provides essential overvoltage margin for 480VAC and 690VAC mains-connected drive and power supply designs
• 25A I_FAV continuous current capacity — suitable for fractional to low-horsepower drive input stages and industrial power conversion
• Isolated copper base substrate — enables direct mounting to standard aluminum or copper heatsinks with electrical isolation maintained, simplifying PCB and chassis integration
• Compact SKD package footprint — industry-standard bolt-down module format compatible with existing SKD-series heatsink and busbar infrastructure
• SEMIKRON-quality silicon die — manufactured to tight forward voltage and leakage current specifications ensuring thermal predictability and long operational life

The SKD 25/16 carries a factory lead time of approximately 38 weeks for new production, a reality that reflects ongoing semiconductor supply chain constraints affecting many SEMIKRON catalog modules. Engineers and procurement teams managing aging drive platforms or legacy industrial equipment cannot afford unplanned downtime while waiting on long-lead factory orders. Sourcing from a stocking distributor with access to genuine OEM inventory is the most effective strategy for protecting critical machine uptime and keeping MRO repair pipelines moving without costly schedule delays.
