GSR2W04

Overview

The GSR2W04 is a single-phase fast recovery bridge rectifier manufactured by Good-Ark Semiconductor. It features a maximum average forward current of 2.0 A and a maximum repetitive peak reverse voltage of 400 V. The device utilizes glass passivated die construction with silver-plated copper leads for enhanced reliability. Key electrical characteristics include a maximum forward voltage drop of 1.3 V at 2.0 A, a peak forward surge current rating of 50 A, and a maximum DC reverse current of 500 µA at rated blocking voltage. The component operates within a junction temperature range of -55°C to +125°C and offers a typical thermal resistance of 40 °C/W.

Feature Summary

• Glass passivated die construction ensures high reliability and stable performance under varying conditions.
• Low profile WOB package design facilitates efficient space utilization in compact circuit layouts.
• Silver plated copper leads provide superior conductivity and solderability for robust connections.

Applications

• High-frequency switching power supplies requiring fast recovery characteristics
• DC-DC converter circuits demanding low forward voltage drop

Procurement Notes

Verify the specific part number GSR2W04 against official Good-Ark Semiconductor documentation to confirm technical specifications. Ensure compliance with RoHS standards as indicated in the manufacturer's ordering information. Cross-reference datasheet parameters such as voltage ratings and thermal resistance with system requirements before integration.

Selection Notes

Select the GSR2W04 when a 400 V reverse voltage rating and 2.0 A continuous current capacity are required. Consider the 1.3 V forward voltage drop and 500 µA leakage current for efficiency calculations. Evaluate the 50 A surge current capability against potential transient loads in the application environment.

Part Context

The GSR2W04 belongs to the GSR2W series of fast recovery bridge rectifiers from Good-Ark Semiconductor. This series covers reverse voltage ratings from 50 V to 1000 V, sharing common physical dimensions and packaging styles. The WOB package variant provides a standardized form factor suitable for various through-hole mounting applications across different voltage classes.

Replacement Considerations

Compatible substitutes include other 400 V, 2 A fast recovery bridge rectifiers in similar packages. Verify that replacement components meet or exceed the original 1.3 V forward voltage drop and 50 A surge current specifications. Ensure thermal resistance and operating temperature ranges align with the existing design constraints.
