1N3673

Single Diodes Overview

The Microchip Technology 1N3673 is a single-element standard recovery silicon rectifier diode designed for high-power applications. It features a maximum repetitive reverse voltage of 1000 V and an average forward rectified current rating of 22 A at a case temperature of 50 °C. The device exhibits a maximum forward voltage drop of 1.2 V and a non-repetitive peak surge current capability of 250 A. It operates within a junction temperature range from -65 °C to +200 °C, with a maximum reverse leakage current of 10 µA. The component utilizes the DO-203AA (DO-5) axial leaded package configuration.

Single Diodes Feature Summary

• High thermal stability enabling operation up to 200 °C junction temperature
• Robust surge current handling capability for transient protection
• Low thermal impedance design for efficient heat dissipation in stud mount configurations

Single Diodes Applications

• Industrial power supply rectification
• Battery charging circuits
• Welding equipment power stages

Single Diodes Procurement Notes

Verify the specific manufacturer source, as Vishay also produces equivalent part numbers like VS-1N3673RA with different electrical ratings. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations. Ensure the ordering suffix matches the required package and terminal finish specifications for your assembly process.

Single Diodes Selection Notes

Select this component when high voltage blocking and significant continuous current are required in a single-diode configuration. The 1000 V rating suits mains-frequency rectification, while the 22 A current capacity supports heavy-duty loads. Consider the DO-203AA package constraints for board space and mounting hardware requirements compared to lower-current alternatives.

Single Diodes Part Context

This device belongs to the general category of medium-power silicon rectifier diodes. It serves as a fundamental building block for converting alternating current to direct current in industrial and commercial power electronics systems where reliability under high thermal stress is critical.

Single Diodes Replacement Considerations

The Vishay VS-1N3673RA is a documented alternative but specifies a lower 12 A average forward current rating. Verify if the reduced current capacity meets the application's thermal and load requirements before substitution.
