1N5807URS/TR

Overview

The Microchip Technology 1N5807URS/TR is a military-qualified ultrafast recovery rectifier diode. It features a working peak reverse voltage of 50 V and an average rectified output current rating of 6.0 A at 75°C case temperature, or 3.0 A at 55°C ambient temperature. The device exhibits a maximum reverse recovery time of 30 ns and a forward surge current capability of 125 A. It utilizes a void-less hermetically sealed glass package with one square and one round end cap (URS configuration).

Feature Summary

• Military qualified per MIL-PRF-19500/477 for high-reliability applications.
• Hermetically sealed void-less glass construction with internal metallurgical bonds.
• Ultrafast recovery characteristics suitable for fast switching power supplies.

Applications

• Military and space electronics requiring high reliability.
• Switching power supplies demanding low forward loss.
• Applications necessitating inherent radiation hardness.

Procurement Notes

Verify the specific ordering suffix to confirm the URS package configuration and tape-and-reel packaging format. Confirm that the required qualification level matches the JAN, JANTX, JANTXV, or JANS designation needed for the target application environment. Ensure compliance requirements are met as RoHS compliant versions are available only on commercial grades.

Selection Notes

Select this component when a 50 V reverse voltage rating and 6.0 A current capacity are required in a surface mount form factor. Consider the 30 ns reverse recovery time for high-frequency switching operations. Evaluate thermal management needs based on the junction-to-end cap thermal resistance provided in the datasheet graphs.
