GBPC3504-E4/51

Overview

The Vishay GBPC3504-E4/51 is a glass-passivated single-phase bridge rectifier from the GBPC35 series. It provides a maximum average forward rectified output current of 35 A and a maximum repetitive peak reverse voltage of 400 V. The device features a peak forward surge current capability of 400 A for non-repetitive sine-wave pulses exceeding 1 ms. Electrical characteristics include a typical instantaneous forward drop of 1.1 V at 17.5 A and a maximum reverse DC current of 5 μA at rated blocking voltage. Thermal resistance (junction-to-case) is specified at 1.4 °C/W, supporting operation within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation ensures long-term stability and reliability under various operating conditions.
• Universal terminal design supports snap-on, wire wrap-around, or PCB mounting configurations.
• High surge current capability accommodates transient load demands without failure.
• Low thermal resistance facilitates efficient heat dissipation in compact power supply designs.

Applications

• General purpose AC/DC bridge full wave rectification
• Power supply circuits for home appliances
• Office equipment power conversion
• Industrial automation control systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number with official Vishay documentation. Confirm RoHS compliance status through the specific ordering suffix and material categorization details provided in the datasheet. Ensure that the procurement channel sources directly from authorized distributors to guarantee adherence to Vishay's quality standards and traceability requirements.

Selection Notes

Select this component when an application requires a 35 A continuous current rating with a 400 V reverse voltage withstand capability. Evaluate the thermal management strategy based on the 1.4 °C/W junction-to-case thermal resistance value. Consider the 400 A surge current rating for circuits experiencing high inrush currents. Verify that the mechanical mounting constraints align with the universal terminal options available for the GBPC package.

Part Context

This component belongs to the Vishay GBPC35 series of single-phase bridge rectifiers, which are designed for general-purpose power applications. The series encompasses various voltage ratings ranging from 50 V to 1000 V while maintaining a consistent 35 A current capacity. The GBPC3504 variant specifically addresses 400 V applications, fitting into the broader family alongside models like GBPC3506 and GBPC3508.

Replacement Considerations

Compatible substitutes within the same series include GBPC3506-E4/51 (600 V), GBPC3508-E4/51 (800 V), and GBPC3510-E4/51 (1000 V). These alternatives share identical current ratings and physical dimensions but offer higher reverse voltage capabilities. Ensure the replacement voltage rating meets or exceeds the original circuit requirements.
