1N3212

Single Diodes Overview

The Microchip Technology 1N3212 is a standard recovery rectifier diode designed for high-power applications. It features a maximum DC reverse voltage (Vr) of 400 V and an average forward rectified current (Io) of 40 A. The device utilizes a DO-203AB (DO-5) leaded package with stud mounting capabilities. Key electrical characteristics include a maximum reverse leakage current of 10 µA at 400 V and a typical forward voltage drop of 1.19 V at 90 A. It operates within a junction temperature range of -65°C to +200°C.

Single Diodes Feature Summary

• Standard recovery speed category suitable for general-purpose power conversion
• High thermal stability with extended junction temperature range up to 200°C
• Robust mechanical construction via stud mounting in DO-203AB package

Single Diodes Applications

• Industrial power supply rectification

Single Diodes Procurement Notes

Verify the specific suffix designation, as the provided model number may correspond to variants such as 1N3212R or 1N3212MS. Confirm RoHS compliance status, as historical data indicates some versions may not meet current environmental standards. Ensure the procurement channel provides official datasheets matching the exact part marking to avoid counterfeit components.

Single Diodes Selection Notes

Select this component when designing circuits requiring 400 V blocking capability and 40 A continuous current handling. The DO-203AB stud mount package necessitates compatible heatsinking infrastructure. Evaluate thermal management requirements carefully due to the high forward current and potential power dissipation during operation.

Single Diodes Part Context

This device belongs to the 1N321x series of axial leaded and stud-mounted rectifiers manufactured by Microchip Technology. It serves as a rugged discrete semiconductor solution for medium-to-high power electronics. The series is characterized by standard recovery times and high surge current ratings.

Single Diodes Replacement Considerations

Consult official substitution guides for equivalent parts from other manufacturers. Verify that any replacement matches the 400 V Vr, 40 A Io, and DO-203AB package dimensions.
