1N1345C

Single Diodes Overview

The Microchip Technology 1N1345C is a standard silicon power rectifier diode housed in the DO-203AA (DO-4) axial leaded package. It features a maximum repetitive peak reverse voltage of 300V and an average rectified forward current rating of 16A. The device utilizes glass passivation for environmental protection and offers a high surge current capability, making it suitable for general-purpose power supply applications requiring robust rectification.

Single Diodes Feature Summary

• Glass passivated die construction for enhanced reliability
• Low forward voltage drop characteristics
• High surge current rating capability

Single Diodes Applications

• General purpose power rectification
• AC to DC converter circuits
• Power supply input stages

Single Diodes Procurement Notes

Verify the manufacturer origin, as historical data indicates production by Microsemi Corporation prior to its acquisition by Microchip Technology. Confirm that the component meets RoHS compliance standards if required for your specific assembly process. Ensure the package matches the DO-203AA specification to guarantee mechanical fitment on the printed circuit board.

Single Diodes Selection Notes

Select this component when a 16A continuous current capacity and 300V blocking voltage are required in a traditional axial leaded form factor. Consider the thermal management requirements associated with high-current rectification in enclosed spaces. Evaluate the surge rating against potential inrush currents in the target application to ensure long-term operational stability.

Single Diodes Part Context

This part belongs to the family of standard silicon power rectifiers manufactured by Microchip Technology. It serves as a legacy component often used in industrial equipment and consumer electronics where reliable, high-current rectification is necessary. The DO-4 package provides a robust mechanical connection suitable for through-hole mounting techniques commonly found in older or heavy-duty designs.

Single Diodes Replacement Considerations

Check for direct equivalents from other manufacturers offering identical electrical ratings and pin configurations. Verify that any substitute maintains the same DO-203AA package dimensions and lead spacing to ensure compatibility with existing footprints.
