Single Diodes Procurement Notes

Verify the manufacturer designation carefully, as the 1N459A series is produced by multiple vendors including onsemi and Microchip. Confirm that the specific suffix matches the required package and tape-and-reel specifications. Cross-reference datasheets to ensure electrical parameters align with your circuit requirements before finalizing procurement.

Single Diodes Selection Notes

Select this component when hermetic sealing and double plug construction are required for harsh environments. The tight forward voltage tolerance makes it suitable for precision signal processing. Ensure the through-hole DO-35-2 package fits the PCB layout constraints and thermal management needs of the target application.

Single Diodes Part Context

This part belongs to the JEDEC registered 1N457A through 1N459A series. These diodes are characterized by their diffused silicon planar technology and robust mechanical construction. The series is widely recognized for its reliability in critical electronic systems requiring stable switching characteristics.

Single Diodes Replacement Considerations

Direct substitutes include other manufacturers' versions of the 1N459A, such as those from onsemi or New Jersey Semi-Conductor Products. Verify pinout compatibility and ensure equivalent thermal and electrical ratings before substitution.
