KBPC2504W

Overview

The GeneSiC Semiconductor KBPC2504W is a single-phase silicon bridge rectifier in the KBPC-T/W package. It features a maximum average forward rectified current (IO) of 25 A and a repetitive peak reverse voltage (VRRM) of 400 V. The device supports a peak forward surge current (IFSM) of 350 A for an 8.3 ms half-sine wave. Electrical characteristics are specified at Tc = 25 °C, with a typical junction capacitance of 300 pF measured at 1 MHz. Thermal resistance (RΘJC) is 1.9 °C/W when mounted on a 300 mm x 300 mm x 1.6 mm copper plate heatsink. Operating and storage temperatures range from -55 °C to +150 °C.

Feature Summary

• High efficiency single-phase rectification using silicon junction technology
• Robust metal case encapsulation designed for mechanical mounting via screw hole
• Non-ESD sensitive construction suitable for standard handling procedures

Applications

• General purpose AC to DC power supply conversion
• Industrial equipment requiring high surge current tolerance
• Resistive or inductive load rectification circuits

Procurement Notes

Verify the specific suffix 'W' against official documentation to confirm physical terminal configuration differences compared to the 'T' variant. Ensure thermal management design accounts for the specified RΘJC value under actual operating conditions. Confirm that the 400 V rating aligns with system peak reverse voltage requirements including transient spikes.

Selection Notes

Select this component for applications requiring 25 A continuous current and 400 V blocking capability. Consider the KBPC-W package dimensions for PCB layout compatibility. Derate current by 20% if used with capacitive loads. Verify ambient temperature constraints relative to the -55 °C to +150 °C junction temperature range.

Part Context

This part belongs to the KBPC25005T/W through KBPC2504T/W series, covering voltages from 50 V to 400 V. The KBPC2504W specifically denotes the 400 V version within the KBPC-W package family. It shares electrical parameters with the KBPC2504T except for potential mechanical differences defined by the package suffix.

Replacement Considerations

Direct substitutes include the KBPC2504T which shares identical electrical specifications. Other manufacturers offering KBPC-2504 equivalents may be considered if package dimensions and pinout configurations match exactly.
