The SEMIKRON SKD33/16 is a 3-phase diode bridge rectifier module rated for 33A average output current and 1600V repetitive peak reverse voltage. Built around SEMIKRON's proven SKD platform, this module integrates a full three-phase bridge rectifier topology within a single isolated-base housing, reducing board space and simplifying thermal management. It is optimized for use in uncontrolled front-end rectifier stages where stable DC bus voltage, low forward drop, and robust transient blocking are critical to system reliability and uptime.

The SKD33/16 is widely deployed in industrial variable-speed drives, servo amplifiers, UPS systems, welding power supplies, and DC motor controllers operating from 3-phase mains. Its 1600V voltage class provides the design margin required when rectifying 690V AC lines or operating in environments with significant voltage transients. The module's isolated copper baseplate enables direct mounting to a heatsink without supplemental isolation hardware, making it a preferred choice for system integrators and OEM drive manufacturers requiring repeatable, high-density power conversion building blocks.

Key Features of the SKD33/16:

• Full 3-phase bridge topology with six integrated diodes in a single compact module package
• 1600V V_RRM rating delivers robust blocking margin for 480V and 690V 3-phase mains applications
• 33A I_FAV continuous output current suitable for industrial drive front-end rectifier stages
• Isolated copper baseplate construction allows direct heatsink mounting without additional insulating hardware
• SEMIKRON SKD platform offers low thermal resistance junction-to-case for efficient heat dissipation at rated load
• Screw-terminal connections provide secure, low-impedance interface to bus bars and high-current PCB designs

The SKD33/16 carries a factory lead time of approximately 28 weeks for new production, placing it firmly in the long lead time category. For maintenance engineers facing unplanned downtime or procurement teams managing MRO and capital equipment spares, waiting seven months for OEM production is rarely an option. ATI Accurate Technology maintains an active sourcing network specifically targeting hard-to-find and extended lead time SEMIKRON components. Whether you need a single replacement module or buffer stock for a fleet of drives, ATI can assess availability, verify authenticity, and move quickly to protect your production schedule.
