1N6620E3/TR

Overview

The Microchip Technology 1N6620E3/TR is a single fast recovery rectifier designed for through-hole mounting in an A-Package-2 (DO-41) axial leaded configuration. It features a maximum repetitive reverse voltage of 200 V and supports a continuous forward current of 2 A. The device exhibits a typical forward voltage drop of 1.6 V at rated current and a maximum reverse leakage current of 500 nA. Key performance metrics include a fast recovery time of 45 ns and a peak non-repetitive surge current capability of 20 A. It operates within a junction temperature range of -65°C to +150°C and is supplied in bulk packaging.

Feature Summary

• Fast recovery characteristics with a 45 ns switching speed suitable for high-frequency applications
• High thermal stability with a maximum operating junction temperature of +150°C
• Robust surge handling capability with a 20 A peak forward surge rating

Applications

• General-purpose rectification in power supply circuits
• Free-wheeling diodes in inductive load switching applications
• DC-AC inversion stages requiring fast recovery performance

Procurement Notes

Verify the specific suffix 'E3' indicates lead-free compliance and 'TR' denotes tape-and-reel packaging, as standard '1N6620' variants may differ in termination finish or container type. Confirm that the A-Package-2 designation aligns with your PCB footprint requirements. Ensure the 200V reverse voltage rating meets the peak inverse voltage demands of your target circuit design before finalizing procurement.

Selection Notes

Select this component when a 2A axial rectifier with fast recovery properties is required. The 200V rating distinguishes it from lower-voltage counterparts like the 1N6620 (often 200V but verify exact datasheet limits) or higher-voltage series members. Consider the 45 ns recovery time against slower standard recovery diodes if minimizing switching losses is critical. Verify RoHS compliance status via official documentation if environmental regulations apply to the end product.

Part Context

This part belongs to the 1N662x series of fast recovery rectifiers manufactured by Microchip Technology. The series offers various voltage ratings ranging from 200V to 1100V while maintaining consistent current handling capabilities. The 'E3' suffix typically signifies lead-free construction, adhering to modern environmental standards. This specific variant provides a balance of moderate voltage blocking and fast switching speeds in a traditional axial package.

Replacement Considerations

Direct substitutes include other 1N6620 equivalents from different manufacturers provided they match the 200V Vr, 2A If, and 45 ns trr specifications. Verify pinout compatibility and package dimensions (A-Package-2/DO-41) to ensure mechanical fit. Cross-reference thermal resistance and reverse leakage characteristics to guarantee equivalent electrical performance under identical operating conditions.
