GBPC1204W-E4/51

Overview

The GBPC1204W-E4/51 is a glass-passivated single-phase bridge rectifier from Vishay General Semiconductor, rated for a maximum average forward rectified output current of 12 A and a maximum repetitive peak reverse voltage of 400 V. It features a quad circuit configuration in a GBPC-W package with wire leads. Key electrical parameters include a typical reverse leakage current of 5 μA at rated DC blocking voltage, a maximum instantaneous forward drop of 1.1 V per diode at 6 A, and a peak forward surge current capability of 200 A. The device operates within a junction temperature range of -55 °C to +150 °C and exhibits a typical thermal resistance of 1.9 °C/W.

Feature Summary

• Glass passivation provides long-term stability and protection against mechanical stress.
• Universal terminal design supports snap-on, wire wrap-around, or PCB mounting configurations.
• High surge current capability ensures robustness during transient load conditions.

Applications

• General purpose AC/DC bridge full wave rectification
• Power supply circuits
• Home appliances
• Office equipment
• Industrial automation applications

Procurement Notes

Verify the specific ordering suffix to confirm lead frame material and compliance status. The E4 suffix indicates RoHS compliance and halogen-free construction. Confirm the W suffix denotes wire leads rather than faston lugs. Ensure the /51 package code matches the required paper box delivery mode. Cross-reference the document number 88612 for the latest revision date before finalizing procurement specifications.

Selection Notes

Select this component when a 12 A continuous current rating and 400 V reverse voltage are required. The GBPC-W package is suitable for applications needing wire termination instead of panel mounting. Verify that the 1.1 V forward voltage drop aligns with efficiency targets. Ensure the operating environment stays within the specified -55 °C to +150 °C junction temperature range. Consider the 200 A surge rating for inrush current handling capabilities.

Part Context

This part belongs to the GBPC series of single-phase bridge rectifiers manufactured by Vishay General Semiconductor. The series includes variants with different current ratings (12 A, 15 A, 25 A, 35 A) and voltage ratings (50 V to 1000 V). The GBPC1204W-E4/51 specifically combines the 12 A current rating with the 400 V voltage rating in a wire-lead package format.

Replacement Considerations

Direct substitutes within the same family include GBPC1202W-E4/51 (200 V), GBPC1206W-E4/51 (600 V), and GBPC1208W-E4/51 (800 V). Other manufacturers may offer equivalent 12 A, 400 V bridge rectifiers in similar packages, but pinout and thermal characteristics must be verified.
