GBPC3508/1

Overview

The GBPC3508/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features an average forward current of 35 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a glass passivated junction for environmental stability and is housed in a GBPC module package with screw mounting terminals. Key electrical parameters include a maximum non-repetitive peak forward surge current of 400 A, a maximum RMS input voltage of 560 V, and a maximum DC blocking voltage of 800 V. Thermal performance is characterized by a junction-to-case thermal resistance of 1.5°C/W and a power dissipation rating of 83.3 W. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Glass passivated junction construction ensures high reliability and resistance to environmental variations.
• Integrally molded heatsink design facilitates efficient thermal management during operation.
• Solderable terminals compliant with MIL-STD-202 standards provide robust mechanical connections.

Applications

• General purpose AC to DC conversion in power supplies
• Battery charging circuits
• DC motor drive systems

Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm terminal configuration and marking details. Ensure that the procurement source provides documentation confirming compliance with RoHS directives where applicable. Cross-reference the part number with authorized distributors to validate authenticity and traceability before finalizing acquisition.

Selection Notes

Select this component when a 35 A continuous current rating and 800 V blocking voltage are required for single-phase rectification. Evaluate the thermal resistance and power dissipation capabilities against the expected ambient temperature and cooling conditions. Confirm that the GBPC package dimensions and screw mounting requirements align with the target PCB or chassis layout constraints.

Part Context

This component belongs to the GBPC series of bridge rectifiers from Vishay, designed for general-purpose applications. The series offers various current ratings and voltage options within a standardized package footprint. The GBPC3508 variant specifically addresses mid-power requirements, balancing current handling capacity with compact physical dimensions suitable for industrial and commercial equipment.

Replacement Considerations

Direct substitutes include the VS-GBPC3508A from Vishay, which shares identical electrical specifications and pinout configuration. Other compatible alternatives may include parts from ON Semiconductor or Fairchild within the same GBPC form factor, provided they meet the 35 A and 800 V criteria.
