KBPC5002W

Overview

The GeneSiC Semiconductor KBPC5002W is a single-phase silicon bridge rectifier designed for through-hole mounting. It features a maximum average forward rectified current (IO) of 50 A and a repetitive peak reverse voltage (VRRM) of 200 V. The device supports a peak forward surge current (IFSM) of 400 A under standard half-sine wave conditions. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V per leg at Tc = 25 °C and IF = 25.0 A. Thermal resistance from junction to ambient (RΘJA) is rated at 2.5 °C/W. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Utilizes a metal case encapsulated within the bridge structure for mechanical stability.
• Features high efficiency operation with low power loss characteristics.
• Constructed with non-ESD sensitive silicon junctions.

Applications

• General purpose AC to DC rectification in industrial power supplies
• Battery charging circuits requiring 50 A continuous current
• DC power supply units utilizing screw-mount heat sinks

Procurement Notes

Verify the specific datasheet revision when sourcing, as manufacturing sources may vary. Confirm that the W suffix corresponds to the KBPC-W package variant rather than the T variant. Ensure thermal management plans account for the specified RΘJA values during installation. Cross-reference terminal configurations against the official mechanical drawings before PCB layout finalization.

Selection Notes

Select this component for applications requiring 50 A continuous current handling with a 200 V blocking capability. The KBPC-W package allows for direct screw mounting, simplifying integration into systems needing robust thermal dissipation via external heatsinks. Consider derating the current by 20% if the load is capacitive to ensure reliable operation within the specified thermal limits.

Part Context

This part belongs to the KBPC5000 series, which includes variants ranging from 50 V to 400 V reverse voltage ratings. All members share the same 50 A current rating and similar thermal profiles. The KBPC5002W specifically addresses mid-range voltage requirements within this high-current family, offering a standardized footprint for scalable power design architectures.

Replacement Considerations

Direct substitutes include other manufacturers' KBPC5002 equivalents meeting identical 50 A/200 V specifications. Verify pinout compatibility and thermal resistance values when swapping brands. Generic replacements must support the same #10 screw mounting configuration to maintain mechanical integrity.
