1N3899R

Single Diodes Overview

The Microchip Technology 1N3899R is a standard recovery rectifier diode designed for high-current applications. It features a maximum DC reverse voltage (Vr) of 50 V and an average forward rectified current (Io) of 20 A. The device utilizes a DO-203AB (DO-5) stud mount package, suitable for panel mounting. Key electrical parameters include a maximum reverse leakage current of 50 µA at 50 V and a typical forward voltage drop of 1.4 V at 63 A. The junction temperature range spans from -65°C to +150°C, with a reverse recovery time (trr) of 200 ns.

Single Diodes Feature Summary

• High current handling capability with a 20 A average forward rectified current rating.
• Robust thermal performance supporting junction temperatures up to +150°C.
• Standard recovery characteristics optimized for general-purpose rectification tasks.

Single Diodes Procurement Notes

Verify the specific manufacturing date code and lot traceability upon receipt, as this component may not comply with RoHS directives. Confirm that the DO-203AB stud mount configuration matches your thermal management and mechanical assembly requirements. Ensure that the 50 V reverse voltage rating provides sufficient margin for your circuit's peak inverse voltage conditions to prevent breakdown.

Single Diodes Selection Notes

Select this component when a robust, high-current rectifier is required for low-voltage applications. The DO-203AB package facilitates efficient heat dissipation through direct mounting to a heatsink or chassis. Consider the 200 ns reverse recovery time for switching frequency limitations in your design. This part is suitable for environments requiring wide operating temperature ranges.

Single Diodes Part Context

The 1N3899R belongs to the 1N38xx series of standard recovery rectifiers manufactured by Microchip Technology.
