1N4934G R0G

Overview

The 1N4934G R0G is a fast recovery rectifier diode from the Taiwan Semiconductor 1N4933G–1N4937G series. It features a single silicon die in a DO-204AL (DO-41) package with an average forward current of 1 A and a repetitive peak reverse voltage of 100 V. The device supports a surge peak forward current of 30 A and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum forward voltage of 1.2 V at 1 A, a typical reverse recovery time of 200 ns, and a maximum reverse current of 5 µA at 25°C.

Feature Summary

• Fast switching capability for high efficiency applications
• High reliability with low leakage current
• High surge current capability
• RoHS compliant and halogen-free construction

Applications

• DC to DC converters
• Switching mode converters and inverters
• General purpose rectification

Procurement Notes

Verify that the specific ordering code matches the required packaging format, as the datasheet lists options such as Tape & Reel or Ammo box. Confirm whether the 'H' suffix for AEC-Q101 qualification is necessary for the target application, as the base part number does not inherently imply automotive qualification. Ensure the component meets environmental standards like UL 94V-0 flammability ratings if required by the design specifications.

Selection Notes

Select this component when a 100 V reverse voltage rating and 1 A continuous forward current are required. Consider the 200 ns reverse recovery time for switching frequencies where standard rectifiers may exhibit excessive losses. Evaluate the thermal resistance of 65 °C/W for heat dissipation requirements in the intended enclosure. Verify compatibility with pure tin plated leads for soldering processes per J-STD-002 standards.

Part Context

This device belongs to the 1N4933G through 1N4937G series, which shares identical physical dimensions and thermal characteristics but varies in voltage ratings from 50 V to 600 V. The 1N4934G specifically targets the 100 V segment of this family. All members utilize the same DO-204AL plastic encapsulation and offer similar forward voltage and reverse recovery performance profiles optimized for general-purpose fast recovery applications.

Replacement Considerations

Cross-reference with other manufacturers offering 1N4934 equivalents in the DO-41 package. Verify that substitute parts maintain the 100 V VRRM, 1 A IF, and comparable trr specifications. Check for any differences in lead plating materials or mechanical mounting constraints.
