1N4933G R0G

Overview

The 1N4933G R0G is a fast recovery rectifier diode manufactured by Taiwan Semiconductor Corporation. It features a single silicon die in a DO-204AL (DO-41) package with an average forward current rating of 1 A and a repetitive peak reverse voltage of 50 V. The device supports a surge peak forward current of 30 A and operates within a junction temperature range of -55 to +150 °C. Electrical characteristics include a maximum forward voltage of 1.2 V at 1 A, a maximum reverse current of 5 µA at rated voltage and 25°C, and a typical reverse recovery time of 200 ns.

Feature Summary

• Fast switching capability for high efficiency applications
• High reliability construction with low leakage current
• High surge current handling capability

Applications

• DC to DC converter circuits
• Switching mode power supplies and inverters
• General purpose rectification tasks

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm packaging type and quantity. Confirm RoHS compliance and halogen-free status requirements match project specifications. Ensure the component meets AEC-Q101 qualification if automotive application standards are required, as indicated by the 'H' suffix variant in the datasheet.

Selection Notes

Select this component for designs requiring a 50 V reverse voltage rating with a 1 A continuous current capacity. Consider the thermal resistance and derating curves for high ambient temperature environments. Verify that the 200 ns reverse recovery time aligns with the switching frequency requirements of the target circuit topology.

Part Context

This part belongs to the 1N4933G through 1N4937G series of fast recovery rectifiers from Taiwan Semiconductor. The series covers voltage ratings from 50 V to 600 V while maintaining a consistent 1 A forward current rating across all variants. The components share identical mechanical dimensions and electrical performance profiles except for their specific reverse voltage breakdown capabilities.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4933 equivalents in the DO-41 package. Verify that substitute parts meet the same 50 V reverse voltage, 1 A forward current, and 200 ns reverse recovery time specifications.
