1N4936GH

Overview

The 1N4936GH is a fast recovery rectifier manufactured by Taiwan Semiconductor Corporation. It features a single configuration housed in the DO-41 through-hole package. The device supports a maximum average forward rectified current of 1 A and withstands a repetitive peak reverse voltage of 400 V. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 30 A, a maximum DC reverse leakage current of 5 uA at rated voltage, and a typical forward voltage drop of 1.2 V at 1 A. The unit operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Glass-passivated junction structure for high reliability
• Fast switching capability for high efficiency
• Low leakage current performance
• High forward surge current capability

Applications

• General purpose rectification in electronic circuits
• Power supply input stages
• Freewheeling diode applications in inductive loads

Procurement Notes

Verify the specific suffix GH against official manufacturer documentation to confirm exact packaging and environmental compliance status. Confirm RoHS directive alignment and lead-free solderability requirements prior to integration. Ensure the component meets MIL-S-19500 standards if required for the target application environment.

Selection Notes

Select this component when a standard 1 A fast recovery rectifier with 400 V blocking capability is required in a DO-41 package. Consider the 175°C maximum junction temperature rating for high-temperature environments. Evaluate the 150 ns reverse recovery time against circuit switching frequency requirements to ensure adequate performance.

Part Context

This part belongs to the 1N493x series of glass-passivated fast recovery rectifiers. These components are designed for general-purpose use where fast switching and low leakage are necessary. The series utilizes a Superectifier structure to provide cavity-free junction protection and high reliability under demanding conditions.

Replacement Considerations

Cross-reference with other manufacturers' 1N4936 equivalents such as Vishay or onsemi parts. Verify that substitute components match the DO-41 package dimensions and meet the same 1 A, 400 V, and 150 ns reverse recovery specifications.
