KBPC3502-G

Overview

The KBPC3502-G is a single-phase silicon bridge rectifier manufactured by Comchip Technology. It features a maximum average forward rectified current of 35 A and a maximum repetitive peak reverse voltage of 200 V. The device utilizes a GBPC package with screw mount terminals for through-hole installation. Key electrical specifications include a maximum non-repetitive peak forward surge current of 400 A, a maximum DC forward voltage drop of 1.2 V at rated current, and a maximum RMS isolation voltage of 2500 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• High thermal stability with an extended operating junction temperature range up to 150 °C
• Robust surge current handling capability of 400 A for transient protection
• Isolated flange design enabling direct mounting to heatsinks

Applications

• AC-DC power supply circuits requiring 35 A output
• Battery charging systems
• General-purpose rectification in industrial equipment

Procurement Notes

Verify the specific manufacturer designation when sourcing, as the KBPC3502 part number is utilized by multiple semiconductor vendors including Vishay, onsemi, and Yangjie. Confirm that the suffix "-G" corresponds to Comchip Technology's standard packaging and material specifications. Ensure the procurement documentation explicitly lists the GBPC package type and screw-mount terminal configuration to match the required PCB footprint and mechanical assembly constraints.

Selection Notes

Select this component for applications demanding a 35 A continuous current rating with a 200 V reverse voltage withstand capability. The GBPC form factor is suitable for designs requiring high current density and efficient heat dissipation via chassis mounting. Verify that the system's peak reverse voltage does not exceed the 200 V limit under all operating conditions and transient scenarios.

Part Context

This component belongs to the general-purpose single-phase bridge rectifier category. It is designed for use in environments where reliable AC-to-DC conversion is necessary. The device integrates four silicon diodes in a single encapsulated unit, simplifying circuit layout compared to discrete diode arrangements.

Replacement Considerations

Direct functional substitutes include the KBPC3502 from Vishay and the GBPC3502 from onsemi. These alternatives share identical electrical ratings and the GBPC package outline. Verify pin compatibility and mounting hole dimensions before substitution.
