KBPC2508T

Overview

The GeneSiC Semiconductor KBPC2508T is a single-phase silicon bridge rectifier rated for a repetitive peak reverse voltage of 800 V and a maximum average forward rectified current of 25 A. It utilizes the KBPC-T through-hole package with solder pin termination. Key electrical parameters include a maximum instantaneous forward voltage of 1.1 V per leg, a peak forward surge current capability of 350 A, and a typical junction capacitance of 300 pF. The device operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• High efficiency rectification using silicon junction technology
• Robust metal case encapsulation for mechanical stability
• Designed for mounting via hole for #10 screw

Applications

• General purpose AC to DC power conversion circuits
• Industrial power supply units requiring high surge tolerance
• Resistive or inductive load applications at 60 Hz

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer marking on the case with the official datasheet specifications. Confirm the specific package variant (KBPC-T) matches the required mounting configuration. Check for discontinuation status as distributor records may indicate end-of-life notifications. Ensure thermal management design accounts for the specified thermal resistance values under actual operating conditions.

Selection Notes

Select this component when an 800 V blocking voltage and 25 A continuous current rating are required. Compare the 350 A surge current capability against expected inrush currents in the target circuit. Evaluate the thermal resistance of 1.9 °C/W to determine appropriate heatsinking requirements. Consider the -55 °C to +150 °C operating range for environmental compatibility.

Part Context

The KBPC2508T belongs to the KBPC25 series of single-phase bridge rectifiers from GeneSiC Semiconductor. This series includes variants with different voltage ratings ranging from 600 V to 1000 V while maintaining a consistent 25 A current rating and physical footprint. The KBPC-T package denotes a specific through-hole mounting style distinct from surface-mount alternatives.

Replacement Considerations

Compatible substitutes include other 800 V, 25 A bridge rectifiers in the KBPC-T package. Verify that replacement parts match the 1.1 V forward voltage drop and 350 A surge current specifications. Ensure the alternative component supports the same -55 °C to +150 °C operating temperature range.
