2W04G-E4/51

Overview

The Vishay 2W04G-E4/51 is a single-phase bridge rectifier utilizing glass-passivated silicon die. It provides an average forward current of 2 A and a repetitive peak reverse voltage of 400 V. The device features a WOG-4 through-hole package with solder pin termination. Key electrical parameters include a maximum non-repetitive peak forward surge current of 60 A, a typical reverse leakage current below 0.5 μA, and a maximum junction temperature of +150 °C. The component operates within a temperature range of -55 °C to +150 °C.

Feature Summary

• Glass-passivated die for enhanced environmental stability
• High case dielectric strength for reliable operation
• UL recognized (File Number E54214) for safety compliance

Applications

• Printed circuit board mounting in power supplies
• General-purpose AC to DC conversion circuits
• Industrial control systems requiring robust rectification

Procurement Notes

Verify the specific suffix E4/51 against the manufacturer datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure compatibility with RoHS directives if required by the end application. Cross-reference the Mouser number 625-2W04G-E4 for accurate distributor identification.

Selection Notes

Select this component when a 2 A continuous current rating and 400 V blocking voltage are required in a compact through-hole format. Compare the 1.1 V forward voltage drop at full load against alternative bridge rectifiers to assess thermal management needs. Confirm that the WOG-4 package dimensions fit the available PCB real estate.

Part Context

This part belongs to the Vishay General Semiconductor 2W series of single-phase bridge rectifiers. The series includes variants with different reverse voltage ratings such as 50 V, 100 V, 200 V, 600 V, 800 V, and 1000 V. All members share the same WOG-4 package style and 2 A current capability, differing primarily in their peak inverse voltage specifications.

Replacement Considerations

Direct substitutes within the same Vishay family include 2W02G, 2W06G, and 2W08G, provided the voltage requirements align. Other manufacturers offering equivalent 2 A, 400 V bridge rectifiers in WOG-4 packages should be evaluated for matching electrical characteristics and mechanical footprint.
