GBPC2504W

Overview

The onsemi GBPC2504W is a single-phase bridge rectifier from the GBPC25 series, rated for a maximum repetitive reverse voltage of 400 V and an average rectified forward current of 25 A at a case temperature of 55°C. It features a non-repetitive peak forward surge current capability of 300 A. The device utilizes a wire lead structure (suffix W) within a GBPC-W package, providing an isolated voltage from case to lead exceeding 2500 V. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 12.5 A and a maximum reverse current of 5 µA at 25°C.

Feature Summary

• Integrally molded heat sink design provides very low thermal resistance for efficient heat dissipation.
• Offers high surge overload ratings up to 300 A for robust transient handling.
• Provides electrical isolation between the case and leads with a rating over 2500 V.

Applications

• General-purpose AC to DC power supply circuits
• Battery charging systems
• Industrial motor drive rectification

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct terminal configuration. Confirm that the component meets all required environmental standards and regulatory certifications relevant to the target application before finalizing procurement specifications.

Selection Notes

Select this component based on the 400 V reverse voltage requirement and 25 A continuous current capacity. Ensure the PCB layout accommodates the GBPC-W package dimensions and allows for adequate airflow or heatsinking to maintain junction temperatures within the specified -55°C to +150°C operating range.

Part Context

This part belongs to the onsemi GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers. The 'W' suffix specifically denotes a wire lead structure variant, distinguishing it from standard solder pin versions. These devices are designed for general-purpose applications requiring reliable rectification in compact packages.

Replacement Considerations

Direct replacements must match the 400 V rating, 25 A current capacity, and GBPC-W package form factor. Verify that any substitute component maintains equivalent thermal resistance and surge current capabilities to ensure circuit reliability without redesigning the mounting or cooling infrastructure.

FAQ

What does the 'W' suffix indicate in the GBPC2504W part number?

The 'W' suffix indicates that the device features a wire lead structure, as opposed to the standard solder pin configuration found in other variants of the GBPC series.

What is the maximum isolation voltage between the case and the leads?

The device provides an isolated voltage from the case to the leads of over 2500 V, ensuring safety and electrical separation in high-voltage applications.

What is the thermal resistance from junction to case?

The thermal resistance from junction to case is 1.5 °C/W when mounted with a heatsink, facilitating effective heat dissipation under load.
