1N1346C

Single Diodes Overview

The 1N1346C is a standard silicon rectifier diode manufactured by Microchip Technology. It features a single-phase, one-element configuration housed in the DO-203AA (DO-4) axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 400V and supports an average forward rectified current of 16A. This component is designed for general-purpose power supply applications requiring robust voltage blocking and moderate current handling capabilities.

Single Diodes Procurement Notes

Verify the manufacturer origin, as the part was originally associated with Microsemi before acquisition by Microchip Technology. Confirm RoHS compliance status, as sources indicate conflicting information regarding environmental compliance. Ensure the package type matches the required DO-203AA/DO-4 specification for your PCB layout or chassis mounting needs.

Single Diodes Selection Notes

Select this component when a 400V reverse voltage rating and 16A continuous current capacity are required. The DO-4 package offers specific thermal and mechanical characteristics suitable for through-hole mounting. Consider the silicon material properties for standard switching speeds and forward voltage drops typical of general-purpose rectifiers.

Single Diodes Part Context

This part belongs to the family of standard rectifier diodes used in industrial and commercial electronics. Originally produced by Microsemi Corporation, it is now distributed under the Microchip Technology brand. The DO-4 package is a legacy form factor often found in older equipment designs or specific high-reliability applications requiring axial leads.

Single Diodes Replacement Considerations

Cross-reference with other 16A 400V DO-4 rectifiers from manufacturers like Vishay or Littelfuse. Verify pinout compatibility and thermal resistance values to ensure equivalent performance in the target circuit without redesigning the heat sinking or mounting structure.
