The SEMIKRON SKD60/08 is a three-phase diode bridge rectifier module combining six fast-recovery diodes in a full-wave bridge topology within a single isolated baseplate package. Rated for 60A DC output current and an 800V repetitive peak reverse voltage (VRRM), this module delivers reliable and thermally efficient AC-to-DC rectification. The SKD package format features industry-standard mounting dimensions, an electrically isolated copper baseplate, and screw terminals that simplify integration into existing drive and converter architectures. It is designed to operate across a wide temperature range, making it well-suited for demanding industrial environments.

The SKD60/08 is widely deployed in the front-end rectifier stages of industrial variable frequency drives (VFDs), servo amplifiers, and DC bus power supplies where robust three-phase rectification is required. It also finds application in welding power sources, uninterruptible power supplies (UPS), electrochemical processing equipment, and crane and hoist drive systems. The module's compact footprint and integrated construction reduce component count and PCB real estate compared to discrete diode assemblies, while the isolated baseplate allows direct heatsink mounting without additional isolation hardware in most standard configurations.

Key Features of the SKD60/08:

• 60A average rectified output current (I_DAV) with 800V repetitive peak reverse voltage (V_RRM) for high-reliability three-phase rectification
• Full three-phase bridge topology (6-pulse) integrating six diodes in a single compact module, reducing assembly complexity and potential failure points
• Electrically isolated copper baseplate enables direct mounting to a heatsink without additional isolation pads in standard installations, simplifying thermal management
• Industry-standard SKD package footprint ensures drop-in compatibility with existing drive platforms and simplifies board-level replacement
• Low thermal resistance junction-to-case (R_thJC) supports efficient heat dissipation in high-cycle and continuous-duty industrial applications
• Screw-terminal connections accommodate heavy-gauge wiring appropriate for 60A continuous current service in harsh industrial environments

The SKD60/08 carries a factory lead time of approximately 37 weeks for new production from SEMIKRON, placing it firmly in the long lead time category that can stall drive repair, OEM production lines, and MRO programs. Procurement teams supporting legacy equipment or managing production schedules cannot afford to rely solely on standard distribution channels for parts with this kind of lead time. ATI Accurate Technology actively sources hard-to-find and long lead time SEMIKRON power modules through established supply chain networks, helping customers secure inventory ahead of scheduled maintenance windows or production requirements.

ATI Accurate Technology is headquartered in Palmetto, Florida, and specializes in IGBTs, thyristors, diodes, and rectifier modules—including obsolete and long lead time parts.
