W01G-E4/51

Overview

The Vishay W01G-E4/51 is a single-phase bridge rectifier from the W005G series, designed for general-purpose applications. It features a 50 V repetitive peak reverse voltage (Vrrm) and supports an average forward current (If) of 1.5 A. The device withstands a non-repetitive peak forward surge current (Ifsm) of 50 A. Electrical characteristics include a maximum forward voltage drop (Vf) of 1.0 V and a peak reverse leakage current (Ir) of 5 µA. It operates within a temperature range of -55 °C to +150 °C junction temperature. The component utilizes a through-hole WOG-4 package with solder pin termination.

Feature Summary

• Utilizes glass-passivated junction technology for high reliability and environmental stability
• Features low forward voltage drop to minimize power loss during conduction
• Provides high forward surge capability to handle transient load conditions
• Offers isolated case connection for flexible mounting options

Applications

• Adapters and power supplies
• Battery chargers
• General-purpose rectification in electronic circuits

Procurement Notes

Verify the specific manufacturer part number against official Vishay documentation to ensure compatibility with design requirements. Confirm that the ordering suffix corresponds to the intended packaging configuration. Cross-reference RoHS compliance status with current regulatory standards before finalizing procurement orders.

Selection Notes

Select this component when a 50 V rating is required for single-phase bridge rectification. Ensure the circuit's average current does not exceed 1.5 A and verify that the thermal management system can maintain the junction temperature below 150 °C under maximum load conditions.

Part Context

This part belongs to the Vishay W005G series of single-phase bridge rectifiers. The series includes variants with different voltage ratings, such as the W02G, W04G, W06G, and W08G, which share similar physical dimensions and electrical characteristics except for the peak reverse voltage specification.

Replacement Considerations

Compatible substitutes include other Vishay W005G series parts like W02G-E4/51 or W04G-E4/51 if higher voltage ratings are acceptable. Verify pinout compatibility and thermal performance before substituting.
