Single Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, or JANTXV) required for your application, as these levels dictate the strictness of manufacturing controls and testing. Confirm that the tape-and-reel packaging suffix matches your automated assembly equipment specifications. Ensure compliance with the specified lead material and finish requirements for your soldering process.

Single Diodes Selection Notes

Select this component when hermetic sealing and wide thermal operation are mandatory. The 70V reverse voltage rating suits low-voltage signal processing tasks. Evaluate the 500mW power dissipation limit against your circuit's thermal management capabilities. Consider the copper-clad steel leads for mechanical strength and compatibility with standard through-hole mounting techniques.

Single Diodes Part Context

This part belongs to the Microchip switching diode family characterized by metallurgical bonding and hermetic sealing. It is distinct from commercial equivalents due to its adherence to MIL-PRF-19500/118 standards. The device utilizes a DO-213AA outline case, providing a robust physical structure suitable for demanding aerospace and defense environments where failure is not an option.

Single Diodes Replacement Considerations

Direct replacements must match the MIL-PRF-19500/118 qualification and DO-213AA outline. Verify that substitute parts maintain the same 70V reverse voltage and 500mW power dissipation ratings. Ensure the replacement offers equivalent thermal impedance and hermetic seal integrity to preserve system reliability.
