1N5614US/TR

Overview

The Microchip Technology 1N5614US/TR is a standard recovery rectifier diode designed for surface-mount applications. It features a maximum DC reverse voltage of 200 V and an average forward current rating of 1 A. The device exhibits a typical forward voltage of 1.3 V at 3 A and a reverse leakage current of 500 nA at 200 V. Its junction temperature range spans from -65°C to +200°C, with a reverse recovery time of 2 µs. The component is supplied in a reel package configuration.

Feature Summary

• Hermetically sealed voidless-glass construction utilizing internal metallurgical bonding for high reliability
• Surface-mount SQ MELF package design suitable for automated assembly processes
• Military qualification compliant with MIL-PRF-19500/427 standards

Applications

• High-reliability aerospace systems requiring hermetic sealing
• Military-grade power supply circuits
• Harsh environment electronics where failure is not tolerated

Procurement Notes

Verify the specific suffix TR indicates tape-and-reel packaging distinct from bulk variants. Confirm military qualification status and RoHS exemption requirements prior to ordering. Ensure compatibility with surface-mount assembly equipment specifications. Validate that the 200V rating meets circuit peak inverse voltage demands. Check for any recent product change notifications affecting assembly sites or labeling.

Selection Notes

Select this component when surface-mount implementation is required for military-specified rectifiers. Compare against through-hole equivalents if board space allows alternative mounting styles. Consider the 2 µs recovery time suitability for standard frequency applications rather than high-speed switching. Evaluate thermal management needs given the wide operating temperature range up to 200°C junction.

Part Context

This part belongs to the 1N5614 series of standard recovery glass rectifiers manufactured by Microchip Technology. The US suffix denotes the surface-mount MELF package variant, while the TR suffix specifies reel packaging. These devices are engineered for critical applications demanding long-term stability and resistance to environmental stressors common in defense and aerospace sectors.
