1N3670

Single Diodes Overview

The 1N3670 is a silicon power rectifier diode manufactured by Microchip Technology (formerly Microsemi). It features a DO-203AA (DO-4) stud mount package. The device has a maximum DC reverse voltage of 700 V and an average rectified current rating of 22 A. It is classified as a standard recovery rectifier with a reverse recovery time exceeding 500 ns.

Single Diodes Feature Summary

• High voltage blocking capability for power applications
• Robust stud mount construction for thermal management
• Standard recovery characteristics suitable for general rectification

Single Diodes Applications

• Industrial power supplies
• Battery charging circuits
• General purpose rectification in high voltage systems

Single Diodes Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Microsemi before its acquisition by Microchip. Confirm the specific suffix (e.g., AR) if precise specifications are required, as variations may exist between original Microsemi and current Microchip production runs. Ensure the DO-4 stud package compatibility matches the intended heatsink or mounting hardware.

Single Diodes Selection Notes

Select this component when a high-current, high-voltage rectifier with standard recovery speed is required. The 22 A average current and 700 V reverse voltage ratings define its operational limits. Consider the physical size and thermal requirements associated with the stud mount package compared to surface-mount alternatives.

Single Diodes Part Context

The 1N3670 belongs to the family of standard silicon power rectifiers. It is functionally similar to other DO-4 packaged diodes like the 1N2260 series. These components are designed for robust performance in environments requiring reliable DC conversion and high surge current handling capabilities.

Single Diodes Replacement Considerations

Direct substitutes include the 1N2260 and 1N3670A. Verify pinout and mechanical dimensions when replacing with equivalent part numbers from different manufacturers.
