The SKDH115/12 is a SEMIKRON diode bridge module rated for 115A continuous output current and a 1200V repetitive peak reverse voltage, making it well-suited for robust three-phase rectification in high-power industrial environments. This module integrates a full-bridge diode configuration in a compact SKD package, offering low forward voltage drop, high surge current capability, and reliable thermal performance when properly mounted to a heatsink. It is engineered to meet the rigorous demands of continuous-duty power conversion applications.

The SKDH115/12 is widely deployed in AC variable speed motor drives, industrial UPS systems, regenerative braking circuits, welding equipment, and DC bus front-end rectifiers. Its robust 1200V blocking voltage provides the necessary margin for 690V AC three-phase input lines, while the 115A current rating supports mid-to-large frame drive platforms. Power supply designers and OEM equipment manufacturers rely on this module for consistent rectification performance across wide temperature ranges and challenging electrical environments.

Quick Reference: SKDH115/12

Key Features of the SKDH115/12:

• 1200V repetitive peak reverse voltage (VRRM) providing ample margin for 690V AC three-phase rectification
• 115A average output current (I_Fav) supporting mid-to-large frame industrial drive front ends
• Integrated full-bridge diode topology in a single SKD package, reducing PCB real estate and assembly complexity
• High surge current (I_FSM) rating for reliable operation through AC line transients and startup inrush events
• Isolated baseplate construction enabling direct heatsink mounting and simplified thermal management
• SEMIKRON SKD platform with industry-standard footprint for straightforward drop-in replacement in existing designs

The SKDH115/12 carries a factory lead time of approximately 35 weeks for new production, a reality that increasingly affects maintenance schedules and capital project timelines across industrial sectors. SEMIKRON modules in this current and voltage class have become vulnerable to allocation and extended queues as global demand for power semiconductors remains elevated. Procurement teams planning drive refurbishments, equipment overhauls, or spares inventory builds cannot afford to wait until a failure occurs. ATI Accurate Technology actively works the supply chain to locate genuine OEM stock of long lead time SEMIKRON parts, helping customers avoid costly downtime.
