2W02G

Overview

The 2W02G is a glass-passivated single-phase bridge rectifier manufactured by onsemi. It features a silicon construction with a round plastic epoxy package (Case WOG) and four terminals. The device supports a maximum average forward rectified current of 2.0 A at a case temperature of 75 °C. It offers selectable repetitive peak reverse voltages, including 100 V, 200 V, and 400 V configurations. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 60 A and a typical reverse leakage current below 0.5 μA. The component is rated for operation up to a maximum junction temperature of 150 °C.

Feature Summary

• Glass passivation provides high reliability and protection against mechanical stress and moisture.
• Integrally molded heat-sink design facilitates efficient thermal dissipation.
• High surge current capability ensures robustness during transient overload conditions.

Applications

• Printed circuit board mounting in AC-DC power supply units.
• General-purpose rectification in low-to-medium power electronic devices.
• Adapter circuits requiring compact bridge rectifier solutions.

Procurement Notes

Verify the specific voltage suffix corresponding to the required reverse voltage rating, as the base part number covers multiple voltage variants. Confirm RoHS compliance status and packaging format directly with the manufacturer or authorized distributors. Ensure the selected variant matches the application's peak inverse voltage requirements to prevent breakdown.

Selection Notes

Select the 2W02G variant based on the specific peak reverse voltage needed for the circuit, such as 100 V, 200 V, or 400 V. Consider the 2.0 A average current limit and the 150 °C maximum junction temperature when designing thermal management. The WOG package is suitable for PCB mounting where space constraints exist.

Part Context

The 2W02G belongs to the Vishay General Semiconductor family of glass-passivated single-phase bridge rectifiers, now distributed by onsemi. This series includes various voltage ratings ranging from 50 V to 1000 V within the same physical WOG package outline. The component is designed for applications requiring reliable rectification in compact form factors.

Replacement Considerations

Direct replacements include other 2 A, 400 V bridge rectifiers in the WOG package, such as the 2W04G for higher voltage tolerance. Generic equivalents from manufacturers like Littelfuse or Diodes Inc. may be used if pinout and thermal characteristics match.
