GBPC1504-E4/51

Overview

The GBPC1504-E4/51 is a glass passivated single-phase bridge rectifier from the Vishay GBPC15 series. It features a maximum average forward rectified output current of 15 A and a maximum repetitive peak reverse voltage of 400 V. The device supports a peak forward surge current of 300 A for non-repetitive half-sine wave conditions lasting between 1 ms and 8.3 ms. Electrical characteristics include a typical instantaneous forward drop of 1.1 V at 7.5 A and a maximum reverse DC current of 5 μA at 25 °C. Operating junction and storage temperatures range from -55 °C to +150 °C, with a typical thermal resistance of 1.9 °C/W.

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer part number against 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 a 400 V blocking voltage and 15 A continuous current rating are required. Verify that the application environment remains within the specified -55 °C to +150 °C operating temperature range. Consider the 1.9 °C/W thermal resistance for heatsink sizing calculations if the ambient temperature exceeds standard ratings. Ensure the mechanical mounting method aligns with the universal terminal capabilities.

Part Context

This component belongs to the Vishay GBPC15 series, which encompasses bridge rectifiers rated for 15 A average forward current. The series includes variants with different voltage ratings ranging from 50 V to 1000 V. All members share the same GBPC package outline and general thermal characteristics, differing primarily in their peak reverse voltage and corresponding RMS voltage specifications.

Replacement Considerations

Direct replacements must match the 15 A current rating, 400 V reverse voltage, and GBPC package dimensions. Verify that alternative components offer equivalent surge current capabilities and thermal resistance values to ensure identical circuit performance without requiring layout modifications.

FAQ
