1N3911

Single Diodes Overview

The Microchip Technology 1N3911 is a high-reliability fast recovery rectifier qualified per MIL-PRF-19500/308. It features a peak working reverse voltage of 200 V and an average forward current rating of 50 A at a case temperature of 100°C. The device operates with a junction temperature range from -65°C to 150°C and utilizes a DO-203AB (DO-5) stud mount package.

Single Diodes Feature Summary

• Qualified for high reliability applications under MIL-PRF-19500/308 standards
• Fast recovery performance with specified reverse recovery time characteristics
• Capable of handling high surge forward currents during transient conditions

Single Diodes Applications

• High reliability power conversion systems
• Industrial rectification circuits requiring military qualification
• Power supplies operating in extreme thermal environments

Single Diodes Procurement Notes

Verify the specific revision level and manufacturing origin against the latest datasheet T4-LDS-0144. Confirm that the component meets the exact MIL-PRF-19500/308 requirements for your application. Ensure proper mounting torque is applied to the stud terminal to maintain thermal resistance specifications.

Single Diodes Selection Notes

Select this component when a 200 V reverse voltage rating and 50 A continuous current are required. Consider the DO-203AB package for stud mounting applications. Evaluate the thermal management needs given the 0.8 °C/W junction-to-case thermal resistance and the 150°C maximum junction temperature limit.

Single Diodes Part Context

This part belongs to the 1N39xx series of fast recovery rectifiers, which includes variants with different voltage ratings ranging from 50 V to 400 V. The series is designed for high-reliability environments and offers consistent performance across multiple voltage levels within the same physical package family.

Single Diodes Replacement Considerations

Compatible substitutes include 1N3911A, 1N3911R, and 1N3911AR, which share the same core electrical ratings but may differ in specific qualification levels or packaging suffixes.
