2W04G

Overview

The 2W04G is a silicon single-phase bridge rectifier manufactured by onsemi, formerly Vishay General Semiconductor. It features an average forward current rating of 2 A and a maximum repetitive reverse voltage of 400 V. The device utilizes glass passivation for junction protection and is housed in the WOG case style, which is suitable for printed circuit board mounting. Key electrical parameters include a maximum non-repetitive peak forward surge current of 60 A and a typical reverse leakage current of less than 0.5 μA. The unit operates within a temperature range of -65 °C to 150 °C junction temperature.

Feature Summary

• Glass passivated junctions provide stable performance and long-term reliability under varying thermal conditions.
• High surge current capability allows the device to withstand transient overloads during power-up or fault conditions.
• Designed specifically for efficient surface-mount integration onto printed circuit boards using the WOG package.

Applications

• General-purpose AC to DC conversion in low-power power supply circuits.
• Bridge rectification in consumer electronics requiring compact PCB-mounted solutions.
• DC power supplies for small appliances and industrial control systems.

Procurement Notes

Verify the manufacturer origin carefully, as the component was originally produced by Vishay before being acquired by onsemi. Confirm that the specific ordering suffix matches the required packaging format, such as tape and reel or tube, as these do not alter the electrical function but affect handling. Ensure compliance with relevant safety standards like UL recognition if required for end-product certification.

Selection Notes

Select this component when a 2 A continuous current and 400 V blocking voltage are sufficient for the application. Consider the WOG package dimensions for PCB layout constraints. Evaluate thermal management requirements based on the 150 °C maximum junction temperature limit. Compare against other voltages in the 2W0xG series if different reverse voltage ratings are needed.

Part Context

The 2W04G belongs to the 2W0xG family of glass-passivated single-phase bridge rectifiers from onsemi. This series includes variants with reverse voltage ratings ranging from 50 V to 1000 V, all sharing the same 2 A current rating and WOG package. The family is designed for cost-effective, reliable rectification in space-constrained electronic designs.

Replacement Considerations

Direct substitutes within the same family include 2W01G (50 V), 2W02G (200 V), 2W06G (600 V), 2W08G (800 V), and 2W10G (1000 V). Cross-manufacturer replacements must match the 2 A current, 400 V voltage, and WOG package footprint. Verify pinout compatibility and thermal characteristics before substitution.
