1N5620US

Overview

The Microchip Technology 1N5620US is a standard recovery rectifier designed for surface-mount applications. It features an 800 V maximum repetitive reverse voltage and supports a continuous forward current of 1 A. The device utilizes the SQ-MELF package, specifically the A-Package-2 configuration. Key electrical characteristics include a forward voltage of 1.3 V at rated current, a peak surge current capability of 30 A, and a low reverse leakage current of 500 nA. The component exhibits a reverse recovery time of 2 µs and operates within a junction temperature range of -65°C to +200°C.

Feature Summary

• Hermetically sealed construction using void-less glass technology for enhanced reliability in harsh environments.
• Internal metallurgical bond ensures structural integrity and long-term stability under thermal stress.
• Qualified to MIL-PRF-19500/406 standards, meeting rigorous military specifications for high-reliability circuits.

Applications

• High-reliability aerospace power supply systems
• Military-grade electronic equipment requiring hermetic sealing
• Avionics components subject to extreme temperature variations

Procurement Notes

Verify that the specific ordering suffix matches the required qualification level (e.g., JAN) as commercial variants may differ in testing or packaging. Confirm RoHS status, as military-qualified versions often carry non-compliance markings. Ensure the SQ-MELF footprint aligns with PCB design constraints before finalizing procurement orders.

Selection Notes

Select this component when high-voltage isolation and hermetic sealing are critical requirements. The 800 V rating suits medium-to-high voltage rectification tasks. Consider the SQ-MELF package for automated surface-mount assembly while maintaining through-hole equivalent performance metrics. Validate thermal management strategies given the wide operating temperature range.

Part Context

This part belongs to the 1N56xx series of standard recovery rectifiers manufactured by Microchip Technology. It shares core electrical parameters with other members of the family but differs in package type and qualification level. The US suffix typically denotes the surface-mount SQ-MELF variant, distinguishing it from axial leaded counterparts like the 1N5620.

Replacement Considerations

Direct substitutes include the 1N5620US/TR for reel-packaged equivalents. Verify pinout compatibility and thermal resistance values when considering alternative manufacturers. Ensure any replacement maintains the same MIL-PRF-19500/406 qualification if used in regulated defense or aerospace applications.
