1N1402

Single Diodes Overview

The Microchip Technology 1N1402 is a silicon power rectifier diode designed for general-purpose applications. It features a DO-8 (DO-205AA) package with screw-type mounting, providing robust mechanical stability for high-power environments. The device is rated for a repetitive peak reverse voltage of 500V and a maximum average forward rectified current of 100A. Key electrical characteristics include a maximum DC forward voltage drop of 1.2V at rated current and a low reverse leakage current of 50µA. These specifications ensure efficient AC-to-DC conversion in demanding industrial and power supply circuits.

Single Diodes Procurement Notes

Verify the specific manufacturer source, as the 1N1402 designation is used by multiple producers including Microsemi and Solid State Inc. Confirm that the received component matches the required DO-8 package dimensions and terminal configuration. Ensure the datasheet aligns with the intended thermal and electrical requirements for your specific circuit design before finalizing procurement.

Single Diodes Selection Notes

Select this component when high current handling and mechanical durability are prioritized over compact footprint. The screw-terminal interface requires appropriate mounting hardware and torque specifications. Consider thermal management solutions given the 100A current rating. Verify compatibility with existing PCB or chassis mounting structures that accommodate the DO-8 form factor.

Single Diodes Part Context

The 1N1402 belongs to the family of standard silicon power rectifiers utilizing the DO-8 axial leaded package. This package type is distinct from surface-mount alternatives, offering higher current capacity through direct chassis or heatsink mounting. It serves as a legacy but reliable solution for high-power discrete rectification tasks where board space is less constrained than current density.

Single Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N1402 equivalents such as those from Microsemi or Solid State Inc. Ensure pinout and physical dimensions match exactly. Verify that alternative sources meet the same 500V/100A ratings and DO-8 package standards.
