KBPC5002T

Overview

The GeneSiC Semiconductor KBPC5002T is a single-phase silicon bridge rectifier rated for a maximum average forward rectified current of 50 A. It supports repetitive peak reverse voltages up to 400 V, with specific ratings including a 200 V DC blocking voltage and a 140 V RMS reverse voltage. The device features a typical thermal resistance of 2.5 °C/W per leg and operates within a junction temperature range of -55°C to +150°C. Key electrical parameters include a maximum instantaneous forward voltage of 1.1 V at 25 A and a peak forward surge current capability of 400 A.

Feature Summary

• Utilizes a metal case construction designed for efficient heat dissipation and robust mechanical stability.
• Features glass passivated die construction to ensure low reverse leakage current and high reliability under varying thermal conditions.
• Incorporates an electrically isolated epoxy case that provides maximum heat transfer while maintaining terminal isolation.

Applications

• High-efficiency AC to DC power conversion in industrial power supplies
• Battery charging circuits requiring high surge current tolerance
• General-purpose rectification in equipment operating within extreme temperature ranges

Procurement Notes

Verify the exact manufacturer origin, as GeneSiC branding may appear on components sourced through various distributors or rebranded by third parties. Confirm the suffix 'T' corresponds to the specific KBPC-T package variant detailed in the datasheet. Ensure the component matches the 50 A and 200 V specifications required for your circuit design before finalizing orders.

Selection Notes

Select this component when a 50 A continuous current rating and 200 V reverse voltage are required. The 2.5 °C/W thermal resistance indicates suitability for applications where effective heat sinking is implemented. Consider the 400 A surge capability for inrush current protection. Verify that the mounting hole configuration aligns with the #10 screw requirement specified in the mechanical data.

Part Context

This component belongs to the KBPC5000 series, which includes variants ranging from 50 V to 400 V reverse voltage ratings. All members of this family share the same 50 A current rating and similar thermal characteristics, differing primarily in their peak reverse voltage capabilities. The KBPC5002T specifically addresses mid-range voltage requirements within this high-current bridge rectifier lineup.

Replacement Considerations

Direct replacements must match the 50 A current rating, 200 V minimum reverse voltage, and KBPC-T package dimensions. Verify that substitute parts offer equivalent thermal resistance and surge current ratings to maintain system reliability without redesigning the cooling infrastructure.
