The SEMIKRON SKKD100/14 is a three-phase diode bridge rectifier module rated for 100A average output current and a 1400V repetitive peak reverse voltage (VRRM). Housed in SEMIKRON's industry-standard SKiiP-compatible power module package, this device is engineered for high-reliability rectification in demanding industrial environments. Its robust silicon diode construction, optimized thermal interface, and isolated baseplate make it a proven choice for engineers requiring stable, low-ripple DC bus generation from three-phase AC supplies.

The SKKD100/14 is widely deployed in AC variable frequency drives (VFDs), industrial servo systems, regenerative DC power supplies, UPS front-end rectifiers, and welding equipment. Its 1400V blocking voltage rating provides the necessary margin for 690VAC three-phase line inputs, while the 100A current rating supports mid-to-high power converter stages. The module is also found in crane and hoist drives, elevator controls, and industrial heating systems where reliable rectification under continuous heavy load is critical to system uptime.

Quick Reference: SKKD100/14

Key Features of the SKKD100/14:

• 1400V repetitive peak reverse voltage (VRRM) — suitable for 690VAC three-phase rectification with full transient margin
• 100A average forward current (IFAV) per phase — supports continuous duty in high-power converter stages
• Three-phase full-wave bridge topology in a single integrated module — reduces BOM complexity and assembly time
• Electrically isolated copper baseplate — enables direct mounting to heatsink without additional isolation hardware
• Low forward voltage drop optimized for thermal efficiency — minimizes conduction losses at rated current
• Compatible with standard SEMIKRON SKKD-series mounting footprint — direct drop-in replacement for field service and legacy drive repairs

The SKKD100/14 carries a factory lead time of approximately 26 weeks for new production orders from SEMIKRON. This is typical for high-voltage diode bridge modules in this current class, particularly as global semiconductor capacity remains constrained. Procurement teams supporting production lines, OEM service departments maintaining aging drive inventory, or engineers qualifying second-source components for long-life industrial programs need a distributor with the market reach to locate genuine stock.
