1N5617/TR

Overview

The Microchip Technology 1N5617/TR is a single fast recovery rectifier diode designed for through-hole mounting in an A-Package-2 axial leaded configuration. It features a maximum repetitive reverse voltage of 400 V and an average forward current rating of 1 A. The device exhibits a typical forward voltage drop of 1.6 V at 3 A and a maximum reverse leakage current of 500 nA at 400 V. Its fast recovery characteristics include a reverse recovery time of 150 ns and a maximum non-repetitive peak forward surge current of 25 A. The component operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Fast recovery performance with a 150 ns reverse recovery time suitable for high-frequency switching applications
• High thermal stability supporting operation up to a junction temperature of +175°C
• Robust surge handling capability with a 25 A non-repetitive peak forward current rating

Applications

• High-frequency power supply rectification circuits
• Free-wheeling diodes in inductive load switching
• General-purpose rectification in aerospace or military electronic systems

Procurement Notes

Verify the specific suffix /TR indicates tape and reel packaging when ordering, as standard variants may differ in bulk quantity. Confirm RoHS compliance status, as this series often falls outside standard environmental directives. Ensure the procurement channel provides valid traceability documentation required for qualified components. Cross-reference the manufacturer part number with official datasheets to confirm electrical parameters match design requirements before finalizing orders.

Selection Notes

Select this component when a fast recovery characteristic is required rather than standard soft recovery. Compare the 150 ns reverse recovery time against circuit switching frequencies to ensure minimal switching losses. Evaluate the 400 V reverse voltage rating against peak inverse voltages in the application to maintain adequate safety margins. Consider the axial package form factor for compatibility with existing printed circuit board layouts and mounting constraints.

Part Context

This part belongs to the 1N5615 through 1N5623 series of silicon rectifiers manufactured by Microchip Technology. These devices are commonly utilized in demanding environments where reliability is critical. The series offers various voltage ratings from 200 V to 800 V while maintaining consistent current handling capabilities. The 1N5617 variant specifically addresses applications requiring moderate voltage blocking with fast switching speeds.

Replacement Considerations

Direct substitutes include JANTX1N5617 and JANS1N5617 for enhanced qualification levels. Commercial equivalents such as 1N5617 without the military suffix may be considered if environmental ratings allow. Verify pinout compatibility and package dimensions before substituting to ensure mechanical fit.
