1N5420/TR

Overview

The Microchip Technology 1N5420/TR is a single fast recovery rectifier designed for through-hole mounting in the B-SQ-MELF-2 package. It supports a continuous forward current of 3 A and withstands a maximum repetitive reverse voltage of 600 V. The device features a low forward voltage drop of 1.5 V at rated current and a maximum reverse leakage current of 1 uA. Key performance metrics include a peak forward surge current capacity of 80 A and a typical reverse recovery time of 400 ns. It operates reliably within a junction temperature range of -65°C to +175°C.

Feature Summary

• Fast recovery rectification with 400 ns reverse recovery time
• High thermal stability operating up to +175°C junction temperature
• Robust surge current handling capability of 80 A
• Low leakage current ensuring efficient high-voltage blocking

Applications

• High-frequency power supply circuits
• Free-wheeling diode applications in inductive loads
• DC-DC converter output rectification
• General-purpose high-voltage rectification

Procurement Notes

Verify the specific ordering suffix and reel quantity requirements directly with the manufacturer or authorized distributors before placing orders. Confirm that the B-SQ-MELF-2 package dimensions match your PCB footprint constraints. Ensure compliance with relevant environmental regulations applicable to your region, as RoHS status may vary by production batch. Check current lead times due to potential supply chain variability.

Selection Notes

Select this component when a 600 V rating and 3 A continuous current are required in a compact MELF-style axial package. Consider the 400 ns recovery time suitability for your switching frequency. Compare against standard DO-201AD packages if higher mechanical robustness is needed, noting the size difference. Verify thermal management requirements for the specific application environment.

Part Context

This part belongs to the 1N54xx series of fast recovery rectifiers manufactured by Microchip Technology. It shares functional similarities with other industry-standard fast recovery diodes but offers specific packaging and reliability characteristics defined by Microchip's manufacturing processes. The /TR suffix indicates tape and reel packaging for automated assembly.

Replacement Considerations

Direct substitutes include JAN1N5420/TR for military-grade specifications. Other compatible replacements must match the 600 V reverse voltage, 3 A forward current, and similar recovery time characteristics. Verify pinout compatibility and package dimensions before substitution.
