1N4934GH

Overview

The Taiwan Semiconductor Corporation 1N4934GH is a silicon planar fast recovery rectifier diode designed for high-speed switching applications. It features a peak repetitive reverse voltage of 100 V and a maximum average forward rectified current of 1 A. The device utilizes a DO-204AL (DO-41) axial leaded package, ensuring robust mechanical stability. Key electrical characteristics include a low forward voltage drop and minimal leakage current, with a specified peak reverse recovery time of 50 ns. It operates reliably within a junction temperature range from -65°C to +175°C.

Feature Summary

Fast recovery performance optimized for high-frequency switching circuits
Low forward voltage drop for improved energy efficiency
High surge current capability for transient protection
Molded plastic case with UL flammability classification

Applications

High frequency rectification in power supplies
Free wheeling diodes in inductive load circuits
Snubber circuits for voltage spike suppression
General purpose fast switching applications

Procurement Notes

Verify the specific suffix 'GH' against the manufacturer's official datasheet to confirm exact packaging configuration and compliance status. Ensure the selected variant matches the required DO-204AL package dimensions and lead specifications for your PCB layout. Cross-reference the part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when a 100 V rating and 1 A continuous current are sufficient for the circuit requirements. Consider the 50 ns reverse recovery time for compatibility with the target switching frequency. Evaluate thermal management needs based on the 175°C maximum junction temperature limit and the thermal resistance characteristics of the DO-41 package under expected operating conditions.

Part Context

This component belongs to the 1N493x series of fast recovery rectifiers, which offers various voltage ratings ranging from 50 V to 600 V while maintaining a consistent 1 A current capacity. The series is widely used in general-purpose electronics requiring reliable high-speed switching. The 1N4934 variant specifically provides the 100 V breakdown voltage option within this standardized family.
