Overview
The Microchip Technology 1N6858-1 is a Schottky Barrier Diode designed for high-reliability applications. It features a hermetically sealed glass case conforming to MIL-PRF-19500/444 standards. The device operates with a maximum repetitive peak reverse voltage of 50V and a maximum average forward rectified current of 75mA. It utilizes a DO-204AH (DO-35) through-hole package with copper clad steel leads finished in tin/lead.
Feature Summary
- Hermetically sealed glass construction ensuring environmental stability
- Schottky barrier technology enabling fast switching capabilities
- Compliance with MIL-PRF-19500/444 military reliability standards
Applications
- High-reliability military aerospace circuits
- Low-voltage signal switching applications
- Small-signal rectification in harsh environments
Procurement Notes
Verify the specific suffix designation, as variants such as JANTX or JAN may exist with identical electrical characteristics but different qualification levels. Confirm that the required lead finish and hermetic sealing meet the specific project's environmental stress screening requirements before finalizing procurement.
Selection Notes
Select this component when military-grade reliability and hermetic sealing are mandatory for low-current, low-voltage operations. Ensure the application does not exceed the 75mA average forward current limit. Consider the DO-35 package constraints for PCB layout and thermal management in confined spaces.
Part Context
This part belongs to the 1N6858 series of small-signal Schottky diodes manufactured by Microchip Technology. It is distinct from general commercial equivalents due to its adherence to MIL-PRF-19500 specifications, offering superior consistency and durability for defense and space-oriented electronic systems requiring certified components.
Replacement Considerations
Direct substitutes include other MIL-PRF-19500/444 qualified Schottky diodes from authorized manufacturers. Verify pinout compatibility and ensure the replacement maintains the same hermetic seal rating and lead material specifications to preserve assembly integrity.
