The SEMIKRON SKKH132/16E is a thyristor/diode module engineered for high-power phase-controlled rectification in industrial drive and converter applications. Combining a thyristor and freewheeling diode in a single compact SEMIPAK housing, this module simplifies PCB layout and thermal management while delivering a 132A average on-state current and 1600V repetitive peak off-state voltage. The SKKH series is a well-established platform in SEMIKRON's portfolio, offering robust gate triggering characteristics, low thermal resistance, and proven reliability across high-cycle industrial environments.

The SKKH132/16E is widely deployed in DC motor drive front ends, field excitation controllers, battery chargers, crane and hoist drives, industrial welding equipment, and uninterruptible power supply (UPS) systems. Its half-controlled bridge topology is particularly suited for applications requiring controlled rectification with inherent freewheeling capability, reducing the need for external flyback components. Industries including metals processing, material handling, marine propulsion controls, and heavy machinery OEMs have standardized on this module for its predictable switching behavior and long field service history.

Quick Reference: SKKH132/16E

Key Features of the SKKH132/16E:

• 132A average on-state current (IT(AV)) with 1600V repetitive peak blocking voltage for high-voltage rectifier circuits
• Integrated thyristor and freewheeling diode in a single SEMIPAK module housing for reduced component count and simplified thermal interface
• Low junction-to-case thermal resistance enabling high power density designs with standard heatsink mounting
• Isolated copper baseplate for direct heatsink mounting with electrical isolation from the thermal dissipation path
• Gate trigger characteristics optimized for phase-control firing circuits operating across industrial temperature ranges
• Designed to IEC and SEMIKRON internal quality standards with robust surge current (ITSM) capability for fault-tolerant designs

The SKKH132/16E carries a factory lead time of approximately 34 weeks for new production orders, which is typical of high-current SEMIKRON thyristor modules in the current semiconductor supply environment. For maintenance teams managing aging drives or OEMs needing scheduled production inventory, this lead time makes early procurement planning essential. ATI Accurate Technology actively sources long lead time and hard-to-find SEMIKRON modules, helping engineers and buyers bridge gaps between urgent repair needs and factory availability. Inquire early to avoid costly downtime waiting on production queues.
