KBPC2508W

Overview

The GeneSiC Semiconductor KBPC2508W is a single-phase silicon bridge rectifier rated for a maximum average forward rectified current of 25 A at a case temperature of 55 °C. It features a repetitive peak reverse voltage of 800 V and a DC blocking voltage of 800 V. The device supports a peak forward surge current of 350 A under half-sine-wave conditions. Electrical characteristics include a maximum instantaneous forward voltage of 1.1 V per leg and a typical junction capacitance of 300 pF. Thermal resistance from junction to case is 1.9 °C/W. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Encapsulated in the KBPC-W package with a metal case design for efficient thermal dissipation.
• Constructed using silicon junction technology suitable for high-efficiency rectification applications.
• Features mounting provisions via a hole designed for a #10 screw.

Applications

• General-purpose AC to DC conversion circuits
• Power supply units requiring 800 V isolation
• Industrial equipment operating within standard temperature ranges

Procurement Notes

Verify the manufacturer designation, as some distributor listings associate this part number with Navitas Semiconductor or GeneSiC Semiconductor. Confirm the specific package variant (KBPC-W) matches the mechanical requirements. Ensure the datasheet version aligns with the required electrical tolerances for the 800 V rating before finalizing procurement orders.

Selection Notes

Select the KBPC2508W when an 800 V reverse voltage rating and 25 A continuous current capacity are required. Consider the 1.9 °C/W thermal resistance for heatsink calculations. Derate the forward current by 20% if the load is capacitive rather than resistive or inductive. Verify that the through-hole mounting style fits the PCB layout constraints.

Part Context

This component belongs to the KBPC2506T/W through KBPC2510T/W series of single-phase bridge rectifiers. The series covers voltage ratings from 600 V to 1000 V while maintaining a consistent 25 A current capability. The KBPC2508W specifically addresses the 800 V segment of this lineup.

Replacement Considerations

The KBPC2508T is the through-hole variant within the same series sharing identical electrical specifications. Other models in the KBPC2506T/W to KBPC2510T/W family offer different voltage ratings but maintain the same current and package form factor.
