GBPC1508W-G

Overview

The GBPC1508W-G is a single-phase bridge rectifier manufactured by Comchip Technology. It features an average forward rectified current of 15 A and a maximum repetitive peak reverse voltage of 800 V. The device utilizes a glass passivated junction for enhanced reliability and includes an integrally molded heatsink to provide low thermal resistance for effective heat dissipation. It operates within a junction temperature range of -55°C to +150°C and supports a maximum surge current of 300 A. The component is housed in the GBPC-W package with solder pin termination, designed for through-hole mounting.

Feature Summary

• Glass passivated junction construction ensures high reliability and stability under varying operating conditions.
• Integrally molded heatsink design provides very low thermal resistance for maximum heat dissipation capabilities.
• High surge current capability allows the device to withstand transient overcurrent events effectively.

Applications

• General-purpose power supply circuits requiring reliable AC-to-DC conversion
• Battery charging systems where robust rectification is necessary
• Industrial control equipment utilizing standard bridge rectifier configurations

Procurement Notes

Verify the specific manufacturer part number against official Comchip Technology documentation to ensure authenticity. Confirm that the GBPC-W package variant matches the required PCB footprint and terminal configuration. Check for RoHS compliance status and any relevant environmental directives applicable to the procurement region. Ensure storage conditions adhere to semiconductor handling standards to prevent moisture sensitivity issues before assembly.

Selection Notes

Select this component when an 800 V blocking voltage and 15 A continuous current rating are required in a through-hole bridge rectifier format. The GBPC-W package offers distinct terminal geometry compared to standard GBPC cases; verify mechanical fitment on the target circuit board. Consider the thermal management requirements of the application, as the integrated heatsink aids in dissipating power losses during operation. Ensure the operating environment stays within the specified -55°C to +150°C junction temperature limits.

Part Context

This component belongs to the GBPC series of glass passivated bridge rectifiers from Comchip Technology. The 'W' suffix in the model number typically denotes a specific terminal or packaging variation within the broader GBPC family. These devices are engineered for general-purpose applications, offering a balance of electrical performance and thermal efficiency. The series is widely used in various electronic systems requiring reliable single-phase rectification.

Replacement Considerations

Direct replacements must match the 15 A current rating, 800 V reverse voltage, and GBPC-W package dimensions. Verify that alternative components offer comparable surge current ratings and thermal resistance characteristics. Ensure the replacement also features glass passivation if long-term reliability in harsh environments is required. Cross-reference pinouts to confirm compatibility with existing PCB layouts.
