The SEMIKRON SKD100GAL123D is a three-phase diode bridge rectifier module engineered for demanding industrial power conversion applications. Rated at 100A average output current and a 1200V repetitive peak reverse voltage (VRRM), this module integrates a full three-phase bridge rectifier into a single isolated baseplate package. Its thermally optimized design supports reliable operation across a wide temperature range, making it well-suited for environments where consistent, high-current DC rectification is non-negotiable. The SKD package format simplifies integration into existing drive and converter platforms.

The SKD100GAL123D sees widespread use in AC variable frequency drives, industrial servo systems, UPS platforms, welding power supplies, and DC bus rectifier stages in renewable energy inverters. Anywhere a three-phase mains input must be converted to a stable high-voltage DC bus—at current levels that demand a robust, thermally capable module rather than discrete components—this part delivers. Its isolated copper baseplate allows direct mounting to heatsinks without additional insulation hardware, reducing assembly complexity in OEM and retrofit designs alike.

Key Features of the SKD100GAL123D:

• 1200V VRRM rating provides robust voltage margin above 480V and 690V three-phase mains inputs, accommodating transient overvoltage events common in industrial environments.
• 100A average rectified output current (IFAV) supports high-power DC bus applications without paralleling discrete diodes or multiple modules.
• Isolated copper baseplate construction enables direct heatsink mounting, simplifying thermal management and reducing insulation hardware requirements.
• Industry-standard SKD package format ensures dimensional and pin compatibility with established drive platforms, supporting drop-in replacement scenarios.
• Low forward voltage drop across the diode bridge minimizes conduction losses, contributing to overall system efficiency in continuous duty rectifier stages.
• Designed and qualified to SEMIKRON's rigorous manufacturing standards, ensuring consistent electrical and thermal parameters across production lots—critical for high-volume OEM procurement.
