The SEMIKRON SKKD26/12 is a diode bridge module delivering 26A average output current and 1200V repetitive peak reverse voltage in a robust SKKDxx package format. Designed for three-phase AC-to-DC rectification, it integrates multiple diodes into a single isolated baseplate module, reducing assembly complexity and improving thermal dissipation through direct heatsink mounting. With low forward voltage drop and high surge current capability, the SKKD26/12 is engineered to meet the continuous demands of industrial power electronics environments where reliability and thermal performance are non-negotiable.

The SKKD26/12 is well suited for front-end rectification stages in AC motor drives, servo amplifiers, UPS systems, industrial power supplies, and welding equipment. Its 1200V voltage class provides the necessary voltage headroom for 690VAC line-connected applications, while the 26A current rating covers a broad range of medium-power equipment. The module format is commonly found in replacement and retrofit scenarios across manufacturing, material handling, HVAC, and process control industries where SEMIKRON rectifier modules have long been a standard specification.

Quick Reference: SKKD26/12

Key Features of the SKKD26/12:

• 1200V repetitive peak reverse voltage (VRRM) providing margin for 690VAC three-phase line applications
• 26A average rectified output current (I_Fav) suitable for medium-power drive front ends
• Isolated copper baseplate for direct heatsink mounting and efficient thermal management
• Low forward voltage drop minimizing conduction losses across the rectifier bridge
• High surge current (IFSM) rating for tolerance of line transients and startup inrush conditions
• Compact SKKDxx module footprint compatible with standard SEMIKRON mounting hardware and heatsink profiles

The SKKD26/12 carries a factory lead time of approximately 26 weeks for new production orders, which is a common challenge with SEMIKRON rectifier modules in the current supply environment. For maintenance operations that cannot afford extended downtime, waiting on factory runs is not a practical option. ATI Accurate Technology specializes in locating exactly these types of long-lead-time and difficult-to-source power semiconductor modules, leveraging an established distributor network to fulfill urgent and scheduled requirements for parts that standard distribution channels cannot readily supply.

ATI Accurate Technology is based in Palmetto, Florida and stocks IGBTs, diodes, thyristors, and rectifier modules from leading manufacturers including SEMIKRON. Same-day shipping is available on orders placed before 5PM EST. Whether you need a single replacement module or volume quantities for a planned maintenance program, ATI can support your procurement timeline.
