KBPC3504W

Overview

The GeneSiC Semiconductor KBPC3504W is a single-phase silicon bridge rectifier designed for high-current applications. It features a maximum average forward rectified current (IO) of 35 A and a repetitive peak reverse voltage (VRRM) of 400 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 (VF) of 1.1 V per leg at 17.5 A and a typical junction capacitance (Cj) of 300 pF. The component operates within a temperature range of -55 °C to +150 °C, with a typical thermal resistance (RΘJC) of 1.4 °C/W.

Feature Summary

• High efficiency silicon junction construction
• Metal case encapsulation for robust mechanical stability
• Not sensitive to electrostatic discharge (ESD)
• Universal mounting options including hole for #10 screw

Applications

• General-purpose AC to DC power supply conversion
• Industrial equipment requiring high surge current tolerance
• Battery charging circuits in automotive or marine environments

Procurement Notes

Verify the specific manufacturer source when ordering, as GeneSiC Semiconductor has undergone corporate restructuring and asset acquisitions. Confirm that the datasheet revision date and electrical parameters match the required design specifications. Ensure the package variant corresponds to the intended PCB footprint, distinguishing between T and W suffixes if necessary for mechanical compatibility.

Selection Notes

Select this component for designs requiring 35 A continuous current handling with 400 V blocking capability. Consider the 1.4 °C/W thermal resistance for heatsink calculations, noting that derating is required for capacitive loads by 20%. Verify that the operating environment stays within the -55 °C to +150 °C junction temperature range to ensure reliability and prevent premature failure.

Part Context

The KBPC3504W belongs to the KBPC35005T/W through KBPC3504T/W series, representing a family of single-phase silicon bridge rectifiers. This series covers voltage ratings from 50 V to 400 V while maintaining a consistent 35 A current rating. The W suffix typically denotes the KBPC-W package variant, which shares similar electrical characteristics with the T package but may differ in physical dimensions or terminal configuration.

Replacement Considerations

Cross-reference with other manufacturers offering KBPC3504 equivalents. Verify pinout compatibility and thermal resistance values before substitution. Ensure the replacement part meets the same 400 V VRRM and 35 A IO requirements.
