GBPC1005-E4/51

Overview

The Vishay GBPC1005-E4/51 is a glass passivated single-phase bridge rectifier in the GBPC1 package. It provides a maximum average forward rectified output current of 3.0 A at a case temperature of 60 °C and 2.0 A at an ambient temperature of 25 °C. The device features a maximum repetitive peak reverse voltage (VRRM) of 50 V, with a corresponding maximum RMS bridge input voltage of 35 V and maximum DC blocking voltage of 50 V. Peak forward surge current capability is rated at 60 A for a single sine wave superimposed on rated load. The typical instantaneous forward voltage drop per diode is 1.0 V at an IF of 1.5 A, while the maximum DC reverse current is 5.0 μA at 25 °C. Operating junction and storage temperatures range from -55 to +150 °C.

Feature Summary

• Glass passivation provides stable electrical characteristics and high reliability under varying conditions.
• High surge current capability ensures robustness against transient overcurrent events.
• Silver-plated leads offer excellent solderability compliant with J-STD-002 standards.

Applications

• AC/DC bridge full-wave rectification for switching power supplies
• Power circuits in home appliances
• Rectification stages in office equipment
• Control and power modules in industrial automation

Procurement Notes

Verify component authenticity by checking the manufacturer's marking code and physical dimensions against the official datasheet specifications. Confirm RoHS compliance status via the supplier's documentation, as the E4 suffix indicates lead-free construction. Ensure that the procurement channel provides traceable manufacturing data to validate the product origin and quality assurance protocols.

Selection Notes

Select this component when a low-voltage (50 V) bridge rectifier is required for applications demanding up to 3 A continuous current. Evaluate thermal management requirements carefully, as the current rating drops significantly at higher ambient temperatures. Compare the GBPC1 package size against available PCB space and verify that the mounting torque limits are respected during assembly to prevent mechanical stress on the terminals.

Part Context

This part belongs to the Vishay GBPC1 series of glass passivated bridge rectifiers, which share identical mechanical footprints and general electrical profiles but differ primarily in their voltage ratings. The GBPC1005 variant specifically addresses low-voltage AC-to-DC conversion needs within this family, offering a standardized solution for compact power supply designs requiring reliable full-wave rectification.

Replacement Considerations

Direct replacements must match the 50 V VRRM, 3 A IF(AV), and GBPC1 package dimensions. Verify that substitute components maintain equivalent surge current ratings and thermal resistance characteristics to ensure circuit performance remains unchanged without redesigning the cooling infrastructure.

FAQ

What is the polarity configuration of the GBPC1005?

Polarity is marked on the side of the case, with the positive lead identified by a beveled corner.

How does the forward current rating change with temperature?

The device supports 3.0 A at a case temperature of 60 °C, but the rating decreases to 2.0 A at an ambient temperature of 25 °C when mounted on a PCB.

Is the component suitable for high-temperature environments?

Yes, the operating junction and storage temperature range extends up to +150 °C.
