W04G/1

Overview

The W04G/1 is a single-phase bridge rectifier manufactured by Vishay General Semiconductor - Diodes Division. It utilizes silicon technology and features four internal elements configured for full-wave rectification. The device supports a maximum average forward output current of 2 A and offers a repetitive peak reverse voltage rating of 400 V. 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 forward voltage drop of 1 V at the rated current. It operates within a junction temperature range up to 150 °C and is housed in the WOG plastic epoxy package.

Feature Summary

• Glass passivated chip junctions provide high reliability and environmental stability.
• High case dielectric strength ensures robust performance under electrical stress.
• UL recognized component (File Number E54214) facilitates compliance in end-product designs.
• Designed specifically for efficient mounting on printed circuit boards.

Applications

• Printed circuit board mounted power supply circuits
• General purpose AC to DC conversion
• Bridge rectifier configurations in low-to-medium power electronics

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact packaging and lead times. Ensure the procurement specification matches the required voltage and current ratings for the target application. Cross-reference the UL recognition file number E54214 if regulatory compliance documentation is required for the final assembly.

Selection Notes

Select this component when a 2 A bridge rectifier with 400 V reverse voltage capability is required for PCB mounting. Consider the 60 A surge current rating for applications involving inrush currents. Verify that the 150 °C maximum junction temperature aligns with the thermal management strategy of the host system. Compare the 1 V forward voltage drop against efficiency requirements relative to alternative rectifier technologies.

Part Context

This component belongs to the Vishay 2W0x series of glass-passivated 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, while maintaining a consistent 2 A forward current capacity and WOG package style. This standardization allows for design flexibility across various voltage requirements.

Replacement Considerations

Direct functional substitutes within the same Vishay family include the 2W04G, which shares identical electrical characteristics and package dimensions. Other manufacturers offering equivalent 2 A, 400 V bridge rectifiers in the WOG or similar through-hole packages may serve as alternatives, provided their surge current and thermal ratings meet or exceed the original specifications.
