The SEMIKRON SKKD15/14 is a dual diode bridge module delivering 15A average output current at a 1400V repetitive peak reverse voltage (VRRM). Built on SEMIKRON's proven SKKD platform, this module integrates rectifier diodes in a compact, isolated base package that simplifies heatsink mounting and bus-bar connection. The high voltage rating makes it particularly suited for applications operating from 480V to 690V three-phase mains, where transient overvoltages demand robust blocking capability. Its low forward voltage drop contributes to improved system efficiency across the full load range.

The SKKD15/14 is widely deployed in industrial AC drives, servo amplifiers, UPS systems, DC power supplies, and welding equipment where compact, reliable front-end rectification is critical. The module format reduces assembly complexity compared to discrete diode configurations and provides a consistent thermal interface for predictable junction temperature management. Field service engineers replacing aging rectifier stages in legacy variable-speed drives and industrial power conversion equipment will find the SKKD15/14 a direct, interchangeable solution that restores original performance without redesign.

Key Features of the SKKD15/14:

• 1400V VRRM rating provides robust margin against line-side transients on 480V–690V mains
• 15A average forward current (IFAV) with low forward voltage drop for reduced conduction losses
• Isolated copper base plate enables direct heatsink mounting without additional insulation hardware
• Dual diode configuration in a single module reduces component count and PCB footprint
• SEMIKRON SKKD package format ensures dimensional interchangeability with existing designs and retrofits
• Designed for full-wave bridge rectification in both single-phase and mid-point circuit topologies

With a factory lead time currently exceeding 99 weeks for new production, the SKKD15/14 presents a serious procurement challenge for maintenance teams managing unplanned downtime or scheduled overhauls. SEMIKRON's SKKD series modules are found throughout legacy industrial installations worldwide, meaning replacement demand consistently outpaces standard distribution inventory. ATI Accurate Technology specializes in sourcing exactly these long-lead-time and hard-to-find power semiconductors, maintaining independent stock to bridge the gap between factory schedules and your operational reality. Procuring now against forecasted demand is strongly advisable given current market conditions.
