GBPC2508W

Overview

The onsemi GBPC2508W is a single-phase bridge rectifier from the GBPC25 series, designed for high-power applications. It features an average forward current of 25 A at a case temperature of 55°C and supports a maximum repetitive reverse voltage of 800 V. The device handles a non-repetitive peak forward surge current of 300 A. Electrical characteristics include a maximum forward voltage drop of 1.1 V at 12.5 A and a reverse leakage current of 5 µA at 25°C. Thermal performance is defined by a power dissipation rating of 83.3 W and a junction-to-case thermal resistance of 1.5°C/W. The component operates within a temperature range of -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides very low thermal resistance for efficient heat dissipation.
• High surge overload capability rated up to 300 A for robust transient protection.
• Offers isolated voltage from case to lead exceeding 2500 V for enhanced safety.
• Features silver-plated wire leads suitable for soldering per MIL-STD-208 standards.

Applications

• Power supply circuits requiring high current rectification
• Industrial motor drive systems
• Battery charging equipment

Procurement Notes

Verify the specific ordering suffix 'W' corresponds to the wire lead structure rather than standard pin terminals. Confirm RoHS compliance status and check for any discontinuation notices regarding this part number before finalizing procurement plans. Ensure packaging details match bulk requirements.

Selection Notes

Select the GBPC2508W when an 800 V reverse voltage rating and 25 A continuous current are required. Consider the GBPC-W package variant specifically for through-hole wire lead mounting configurations. Evaluate thermal management needs based on the 1.5°C/W junction-to-case resistance value.

Part Context

This component belongs to the GBPC 12, 15, 25, and 35 series of glass-passivated bridge rectifiers manufactured by onsemi. The GBPC2508W specifically denotes the 25 A current class with an 800 V voltage rating. The 'W' suffix identifies the wire lead version of the GBPC package.

Replacement Considerations

Direct substitutes within the same series include GBPC2506W (600 V) or GBPC2510W (1000 V). Cross-manufacturer equivalents in the GBPC form factor may be considered if electrical parameters align.
