1N2285

Single Diodes Overview

The Microchip Technology 1N2285 is a general-purpose silicon power rectifier diode designed for high-current applications. It features a maximum average forward rectified current of 40 A and a repetitive peak reverse voltage of 600 V. The device utilizes a stud mount configuration within the DO-203AB (DO-5) package, facilitating efficient thermal dissipation through direct mounting to heatsinks. This component is engineered for robust performance in industrial power conversion systems requiring reliable unidirectional current flow.

Single Diodes Procurement Notes

Verify the manufacturer origin, as this part number has been produced by multiple entities including Microsemi and Microchip. Confirm the specific datasheet version matches your design requirements. Ensure the physical package matches the DO-203AB stud mount specification. Check for any ordering suffixes that may indicate variations in packaging or testing standards before finalizing procurement.

Single Diodes Selection Notes

Select this component when designing circuits requiring high surge current tolerance and significant heat dissipation capabilities. The stud mount option is preferred over leaded packages for higher power densities. Evaluate the thermal resistance characteristics against your heatsink solution. Ensure the operating junction temperature range aligns with your environmental constraints.

Single Diodes Part Context

This component belongs to the standard silicon rectifier diode family, historically associated with the 1N series designations. Originally developed by Microsemi Corporation, production rights and inventory have transitioned to Microchip Technology. It serves as a legacy replacement for older discrete rectifier designs in established industrial equipment architectures.

Single Diodes Replacement Considerations

Direct substitutes include other 40 A, 600 V stud-mount silicon rectifiers from manufacturers such as Vishay or Littelfuse. Verify pinout compatibility and thermal interface dimensions. Cross-reference datasheets for forward voltage drop and recovery time differences to ensure circuit stability.
