GBPC50005W

Overview

The GeneSiC Semiconductor GBPC50005W is a single-phase glass-passivated silicon bridge rectifier designed for high-temperature applications. It features a maximum average forward rectified current of 50.0 A and a repetitive peak reverse voltage of 50 V. The device utilizes the GBPC-W package with an integrally molded heat sink to ensure low thermal resistance. Key electrical parameters include a peak forward surge current of 400 A, a maximum instantaneous forward voltage drop of 1.2 V per leg, and a typical junction capacitance of 360 pF. The component supports an operating temperature range from -55°C to +150°C.

Feature Summary

• Integrally molded heat sink provides low thermal resistance for maximum heat dissipation
• Universal 3-way terminals allow snap-on, wire-around, or P.C board mounting
• High surge current capability with void-free junction soldering by vacuum process

Applications

• Power supply circuits requiring 50A continuous current handling
• Industrial equipment operating in high-temperature environments up to 150°C
• General-purpose AC to DC conversion in resistive or inductive loads

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm terminal type and packaging configuration. Ensure that the procurement specifications match the required electrical ratings, particularly the 50V reverse voltage and 50A forward current limits. Confirm compliance with RoHS directives if applicable to the target market. Cross-reference the datasheet revision date to ensure the most recent mechanical and electrical data is utilized for design integration.

Selection Notes

Select this component when a 50A single-phase bridge rectifier with a 50V rating is required. The GBPC-W package offers universal mounting options suitable for bolt-down heat-sink applications. Consider the 1.2V forward voltage drop for power loss calculations at full load. Verify that the application does not exceed the 400A peak surge current limit during startup or fault conditions. Ensure adequate thermal management is provided given the 1.2°C/W junction-to-case thermal resistance.

Part Context

The GBPC50005W belongs to the GBPC-T/W series of single-phase bridge rectifiers manufactured by GeneSiC Semiconductor. This series includes variants with different reverse voltage ratings, such as 100V, 200V, and 400V, while maintaining the same 50A current capacity. The GBPC-W variant specifically denotes the package style with universal terminal configurations. These components are standard industrial-grade silicon rectifiers used in general power electronics applications.

Replacement Considerations

Compatible substitutes include other manufacturers' GBPC50005 equivalents, such as those from Taiwan Semiconductor or onsemi, provided they meet the 50A/50V specification and utilize the GBPC package footprint. Verify that any replacement part maintains the same 1.2V forward voltage drop and 400A surge current rating to ensure circuit compatibility.
