1N1613A

Single Diodes Overview

The Microchip Technology 1N1613A is a general-purpose silicon rectifier diode housed in the DO-203AA (DO-4) axial leaded package. It features a maximum repetitive peak reverse voltage of 100 V and an average forward rectified current rating of 5 A at 75°C. The device supports a non-repetitive surge current of up to 150 A for half-cycle sine waves. With a maximum DC forward voltage drop of 1.1 V at rated current, it is designed for high-temperature operation with a maximum junction temperature of 190°C.

Single Diodes Feature Summary

• High thermal stability enabling reliable operation at elevated temperatures up to 190°C
• Robust surge current handling capability for transient load protection
• Standardized axial leaded package configuration for through-hole mounting

Single Diodes Applications

• General-purpose power supply rectification circuits
• Battery charging systems requiring high surge tolerance
• Industrial control equipment power stages

Single Diodes Procurement Notes

Verify the manufacturer marking on the component body to confirm Microchip Technology origin, as this part number is historically associated with multiple vendors including New Jersey Semi-Conductor. Ensure the package matches the DO-203AA specification and check datasheets for specific electrical tolerances relevant to your design requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when a standard 100V, 5A rectifier is required for through-hole assembly. Consider the 190°C maximum junction temperature limit for thermal management calculations. Verify that the 1.1V forward voltage drop meets efficiency targets compared to Schottky alternatives if low loss is critical.

Single Diodes Part Context

This diode belongs to the standard rectifier family often used in legacy and industrial designs. Similar parts include the 1N1613 and 1N1614 series, which vary primarily in reverse voltage ratings. The DO-203AA package remains common for high-current axial applications where board space is less constrained than surface mount options.

Single Diodes Replacement Considerations

Direct substitutes include the 1N1613 from other manufacturers if voltage ratings align. Verify pinout compatibility and thermal resistance characteristics when replacing with equivalent parts from different suppliers to ensure circuit performance remains within specifications.
