GBPC1202W-E4/51

Overview

The GBPC1202W-E4/51 is a glass passivated single-phase bridge rectifier from Vishay General Semiconductor. It belongs to the GBPC12 series, rated for a maximum average forward rectified output current of 12 A and a maximum repetitive peak reverse voltage of 200 V. The component features wire leads (indicated by the 'W' suffix) and utilizes a GBPC-W plastic package with an isolated case connection. Key electrical parameters include a maximum instantaneous forward drop of 1.1 V at 6.0 A, a typical reverse leakage current of less than 0.3 μA, and a peak non-repetitive forward surge current capability of 200 A. It operates within a junction temperature range of -55 °C to +150 °C.

Feature Summary

• Universal terminal design supporting snap-on, wire wrap-around, or PCB mounting configurations
• High surge current capability combined with low thermal resistance for efficient heat dissipation
• Glass passivation provides excellent stability and reliability under various operating conditions

Applications

• General purpose AC/DC bridge full wave rectification in power supplies
• Rectification circuits for home appliances and office equipment
• Industrial automation control systems requiring robust diode bridges

Procurement Notes

Verify that the ordering suffix matches the required lead type; the 'W' designation specifically indicates wire leads rather than faston lugs. Confirm compliance requirements such as RoHS status and UL recognition file number E54214. Ensure the selected voltage rating aligns with the circuit's peak inverse voltage demands to prevent breakdown during operation.

Selection Notes

Select this component when a 12 A continuous current rating and 200 V blocking voltage are required. The GBPC-W package is suitable for applications needing wire termination instead of panel mounting. Evaluate the thermal environment to ensure the junction temperature remains within the specified -55 °C to +150 °C range under maximum load conditions.

Part Context

This part is a member of the Vishay GBPC12 family of single-phase bridge rectifiers. The series offers various voltage ratings from 50 V to 1000 V while maintaining a consistent 12 A current capacity. The GBPC1202 variant specifically addresses applications requiring 200 V reverse voltage handling within a compact, high-current bridge configuration.

Replacement Considerations

Cross-reference with other GBPC12 series parts like GBPC1204 or GBPC1206 if higher voltage ratings are needed. Verify pinout compatibility and physical dimensions before substituting. Ensure the replacement maintains the same wire lead configuration if the existing board layout requires it.
