GBPC1504T

Overview

The GBPC1504T is a single-phase glass-passivated silicon bridge rectifier rated for a maximum average forward rectified current of 15 A and a repetitive peak reverse voltage of 400 V. It features a maximum instantaneous forward voltage drop of 1.1 V per leg and supports a peak forward surge current of 300 A under single sine-wave conditions. The device operates within a junction temperature range of -55 °C to 150 °C, with a typical thermal resistance of 1.9 °C/W. It utilizes the GBPC-T package, which includes an integrally molded heat sink and universal three-way terminals compatible with snap-on, wire-around, or PCB mounting.

Feature Summary

• Glass passivated junctions provide stable electrical characteristics and protection against external stress.
• Integrally molded heat sink design ensures low thermal resistance for efficient heat dissipation.
• Universal three-way terminal configuration allows flexible installation via snap-on, wire-around, or PCB mounting methods.

Applications

• High-temperature soldering applications requiring reliability at 260°C for 10 seconds
• Bolt-down mounting on heat sinks using silicone thermal compound
• General purpose AC to DC conversion in power supply circuits

Procurement Notes

Verify that the ordered component matches the specific GBPC-T package variant rather than the W variant, as terminal configurations differ. Confirm the manufacturer datasheet specifies the 400 V rating for the 1504 designation. Ensure compliance with RoHS directives if required by the application environment. Check terminal plating specifications against JESD22-B102 standards for solderability requirements.

Selection Notes

Select this component when a 15 A continuous current capacity and 400 V blocking voltage are required in a compact form factor. The GBPC-T package is suitable for applications needing robust mechanical mounting options beyond standard through-hole leads. Consider the 1.9 °C/W thermal resistance for heatsink sizing calculations. Verify that the 300 A surge capability meets the inrush current demands of the specific load circuit.

Part Context

The GBPC1504T belongs to the GBPC series of single-phase bridge rectifiers, which typically spans voltage ratings from 50 V to 800 V while maintaining a consistent 15 A current rating. This series is characterized by its glass passivation technology and integrated heat sink construction. The 'T' suffix denotes the specific terminal style associated with the GBPC-T package format.

Replacement Considerations

Cross-reference with other manufacturers offering GBPC1504 equivalents. Verify that substitute components match the 15 A IO, 400 V VRRM, and 1.1 V VF specifications. Ensure the replacement package maintains compatible mounting dimensions and terminal types for direct interchangeability.
