KBPC3502T

Overview

The GeneSiC Semiconductor KBPC3502T is a single-phase silicon bridge rectifier designed for high-efficiency power conversion. It features a maximum average forward rectified current of 35 A and a repetitive peak reverse voltage of 200 V. The device utilizes the KBPC-T package, which includes a metal case for direct mounting to heatsinks via a screw hole. Key electrical parameters include a maximum instantaneous forward voltage of 1.1 V per leg at 25 °C and a typical thermal resistance of 1.4 °C/W. It supports a wide operating temperature range from -55 °C to +150 °C and withstands a peak forward surge current of 400 A.

Feature Summary

• Utilizes a metal encapsulation case that allows direct mechanical mounting to external heat sinks using a standard screw hole.
• Constructed with silicon junction technology to ensure stable performance across a wide temperature range without ESD sensitivity.

Applications

• High-current AC to DC power supply circuits
• Industrial motor drive rectification stages
• General-purpose bridge rectification in heavy-duty equipment

Procurement Notes

Verify the specific manufacturer designation on the component marking, as GeneSiC assets have been acquired by Navitas Semiconductor. Confirm the package variant matches the required thermal management strategy, as the T suffix indicates a through-hole configuration suitable for screw-mounting. Ensure the datasheet version aligns with the intended operational voltage and current derating requirements.

Selection Notes

Select this component when a 35 A continuous current rating and 200 V blocking capability are required in a robust, thermally conductive package. The low forward voltage drop minimizes conduction losses, while the high surge current rating accommodates inrush conditions. Consider the physical dimensions and screw-mount requirement for PCB layout and chassis integration compared to surface-mount alternatives.

Part Context

This part belongs to the KBPC35 series of single-phase bridge rectifiers, which offers various voltage ratings from 50 V to 400 V. The KBPC3502T specifically addresses applications requiring 200 V reverse voltage. The series is characterized by its standardized KBPC-T package, providing a reliable solution for medium-to-high power applications where efficient heat dissipation is critical for long-term reliability.

Replacement Considerations

Compatible substitutes include the KBPC3502W (same electrical specs, different package variant) or equivalents from other manufacturers such as Vishay or Yangjie, provided they match the 35 A current, 200 V voltage, and KBPC form factor.
