The SEMIKRON SKKH162/14E is a thyristor/diode power module combining a SCR (silicon controlled rectifier) and a fast-recovery diode in a single compact package. Rated at 162A average on-state current and a 1400V repetitive peak off-state voltage (VDRM/VRRM), this module is engineered for high-reliability phase-control and controlled rectifier circuits. The SKKH series package provides isolated base construction, simplifying heatsink mounting and system integration in high-voltage industrial power assemblies where thermal management and electrical isolation are critical design requirements.

The SKKH162/14E is well-suited for industrial DC motor drives, soft-start systems, AC/DC converters, field excitation circuits, and regenerative braking systems. It is commonly deployed in steel mill drives, cranes, elevators, paper machinery, and large HVAC systems where precise power control at medium-to-high current levels is essential. The half-controlled or fully-controlled bridge configurations enabled by this module make it a staple component in legacy and current-generation industrial drive cabinets that demand long service life and high thermal cycling tolerance.

Key Features of the SKKH162/14E:

• 162A average on-state current (IT(AV)) with high surge current capability for robust fault tolerance
• 1400V repetitive peak off-state voltage (VDRM/VRRM) suitable for 690V AC line applications with adequate safety margin
• Integrated thyristor and diode in one isolated-base module, reducing component count and simplifying PCB or busbar layout
• Electrically isolated copper baseplate for direct heatsink mounting without additional isolation hardware
• Low thermal resistance (Rth(j-c)) enabling efficient heat dissipation in high-duty-cycle industrial operation
• Gate trigger characteristics optimized for phase-control firing circuits with standard SCR gate drive requirements

With a factory lead time of approximately 99 weeks for new production, the SKKH162/14E presents a significant procurement challenge for facilities running scheduled maintenance, drive refurbishments, or emergency repairs. SEMIKRON's SKKH-series modules are widely embedded in long-lifecycle industrial equipment, making availability critical when downtime is not an option. ATI Accurate Technology actively sources long-lead-time and allocated SEMIKRON power modules, maintaining relationships across a global supply network to locate genuine OEM inventory when standard distribution channels cannot meet your timeline.
