1N3611E3/TR

Single Diodes Overview

The Microchip Technology 1N3611E3/TR is a standard recovery rectifier diode rated for 200V working peak reverse voltage and 1.0A average rectified forward current. It features a voidless hermetically sealed glass package with tungsten slugs and copper/tin-lead axial leads. Qualified to MIL-PRF-19500/228, the device operates within a junction temperature range of -65°C to +175°C. Electrical characteristics include a maximum forward voltage of 1.1V at 1A pulsed and a maximum reverse current of 1.0µA at VRWM.

Single Diodes Feature Summary

• Military qualified to MIL-PRF-19500/228 for high-reliability applications
• Voidless hermetically sealed glass construction with internal metallurgical bonds
• Inherently radiation hard design
• Robust construction with controlled avalanche capability

Single Diodes Applications

• Military and aerospace systems requiring high reliability
• General rectifier circuits including bridges and half-bridges
• Catch diode applications in power conversion
• High forward surge current environments

Single Diodes Procurement Notes

Verify that the specific ordering suffix matches the required military qualification level (JAN, JANTX, or JANTXV) as defined in the datasheet. Confirm the tape and reel packaging option aligns with EIA-296 standards if automated assembly is planned. Ensure the component meets RoHS exemptions for leaded terminations if applicable to your manufacturing process.

Single Diodes Selection Notes

Select this component when a standard recovery time is sufficient for the application frequency. The 1N3611 variant specifically suits circuits requiring a 200V blocking capability. Consider the thermal resistance of 38°C/W and derating requirements when designing for ambient temperatures above 100°C. Verify lead length constraints against the specified 3/8 inch measurement for thermal calculations.

Single Diodes Part Context

This device belongs to the 1N3611 through 1N3613 series of industry-recognized 1.0 Amp rectifiers. It shares similar ratings with the 1N5614 through 1N5622 series but utilizes an axial leaded package rather than surface mount MELF configurations. The product line is designed for applications where failure cannot be tolerated, offering robust performance across extreme temperature ranges.

Single Diodes Replacement Considerations

Surface mount equivalents are available in square end-cap MELF configurations by adding a 'US' suffix, such as those found in the 1N5614US through 1N5622US series. Direct pin-to-pin replacements must maintain the same voltage rating and hermetic sealing requirements.
