1N1301

Single Diodes Overview

The Microchip Technology 1N1301 is a silicon power rectifier diode designed for general-purpose applications. It features a standard recovery speed and is housed in a DO-5 axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 50V and a continuous forward current of 37A. Key electrical characteristics include a maximum DC forward voltage drop of 1.19V at 90A and a maximum non-repetitive surge current capability of 400A. These specifications define its operational limits within electronic circuits.

Single Diodes Procurement Notes

Verify the manufacturer origin, as the 1N1301 designation has been produced by multiple entities including Microsemi and New Jersey Semiconductor. Confirm that the specific unit received matches the required DO-5 package style and meets the specified 50V/37A ratings. Ensure documentation confirms compliance with the original JEDEC standards associated with this part number to guarantee functional equivalence in critical designs.

Single Diodes Selection Notes

Select this component when a high-current, low-voltage rectifier is required in an axial package. Compare the 37A continuous rating against circuit load requirements. Consider the 1.19V forward voltage drop for thermal management calculations. Ensure the operating junction temperature range aligns with the system's environmental constraints before finalizing the design choice.

Single Diodes Part Context

This component belongs to the legacy 1N series of silicon rectifiers, originally standardized by JEDEC. While historically associated with Microsemi Corporation, Microchip Technology acquired Microsemi's assets. The 1N1301 represents a standard high-current variant within this family, distinguished by its specific 50V voltage rating and substantial current handling capacity compared to lower-rated counterparts.

Single Diodes Replacement Considerations

Equivalent parts include the NJG1N1301 from New Jersey Semiconductor Products Inc. Verify pinout compatibility and ensure the substitute maintains the same DO-5 package dimensions and electrical ratings.
