GBPC2504

Overview

The onsemi GBPC2504 is a single-phase bridge rectifier from the GBPC series, rated for an average forward current of 25 A at a case temperature of 55°C. It features a maximum repetitive reverse voltage (VRRM) of 400 V and a maximum RMS bridge input voltage of 280 V. The device utilizes glass-passivated die construction within a plastic GBPC package with screw mount terminals. Key electrical parameters include a non-repetitive peak forward surge current of 300 A, a maximum forward voltage drop of 1.1 V at 12.5 A, and a reverse current of 5 µA at 25°C. Thermal characteristics specify a junction-to-case thermal resistance of 1.5°C/W and a power dissipation of 83.3 W.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for maximum heat dissipation.
• Glass passivated die construction ensures high reliability and surge overload capability.
• Isolated voltage from case to lead exceeds 2500 V.

Applications

• Power supply circuits requiring single-phase rectification.
• Industrial equipment utilizing screw-mount bridge rectifiers.
• Applications demanding high surge current handling capabilities.

Procurement Notes

Verify component authenticity by checking the marking code against official datasheet specifications. Confirm RoHS compliance status as indicated in ordering information. Ensure mounting torque does not exceed 20 in-lbs during installation to prevent mechanical damage. Validate that the package type matches the required PCB or chassis mounting configuration.

Selection Notes

Select this component when a 25 A continuous current rating and 400 V reverse voltage are required. Consider the GBPC-W variant if wire leads are preferred over screw mounts. Evaluate thermal management requirements based on the 1.5°C/W junction-to-case resistance. Ensure the application environment stays within the -55°C to +150°C operating temperature range.

Part Context

The GBPC2504 belongs to the GBPC 12, 15, 25, 35 Series of bridge rectifiers manufactured by onsemi. This series offers various current ratings and voltage options within the same physical footprint. The GBPC package design allows for efficient heat transfer through the integrated heatsink structure, making it suitable for high-power density applications.

Replacement Considerations

Compatible alternatives within the same series include GBPC2502 (200 V), GBPC2506 (600 V), and GBPC2508 (800 V). For wire-lead versions, consider GBPC2504W. Verify that substitute parts meet the same 25 A current and 400 V voltage ratings.
