GBPC3501-E4/51

Overview

The GBPC3501-E4/51 is a glass passivated single-phase bridge rectifier from the Vishay GBPC35 series. It provides a maximum average forward rectified output current of 35 A and supports a maximum repetitive peak reverse voltage of 50 V. The device features a peak forward surge current capability of 400 A for non-repetitive sine-wave loads lasting between 1 ms and 8.3 ms. Electrical characteristics include a typical junction capacitance of 160 pF per diode at 4 V and 1 MHz, with a maximum instantaneous forward drop of 1.1 V at an IF of 17.5 A. The unit operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Glass passivation ensures reliable operation under standard electrical conditions
• High surge current capability accommodates transient load demands
• Low thermal resistance facilitates efficient heat dissipation during continuous operation

Applications

• AC/DC bridge full wave rectification in power supplies
• Rectification circuits in home appliances
• Power conversion modules for office equipment
• Industrial automation control systems

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's document number 88612 against official Vishay channels. Confirm that the ordering suffix matches the specific package configuration required for the target assembly. Ensure compliance with RoHS directives as indicated by the E4 designation before finalizing procurement orders.

Selection Notes

Select this component when applications require a 35 A continuous current rating with a 50 V blocking voltage threshold. Evaluate the thermal management requirements based on the specified 1.4 °C/W junction-to-case thermal resistance. Verify that the mounting torque does not exceed the maximum limit of 20 inches-lbs to prevent mechanical damage to the housing or terminals.

Part Context

This part belongs to the Vishay GBPC35 family of high-current bridge rectifiers. The series encompasses variants ranging from 12 A to 35 A with reverse voltage ratings spanning 50 V to 1000 V. All members share the standardized GBPC plastic case outline and utilize identical glass passivation techniques for junction protection across the product line.

Replacement Considerations

Direct replacements must match the 35 A current rating, 50 V minimum reverse voltage, and GBPC physical footprint. Verify that alternative components support the same 400 A surge current requirement and maintain compatibility with the existing thermal interface design.
