Single Zener Diodes Procurement Notes

Verify the specific qualification grade (JAN, JANTX, or JANTXV) required for your design, as availability varies by lot. Confirm that the DO-213AA mounting interface matches your thermal management strategy. Ensure compliance with MIL-PRF-19500/124 requirements during acceptance testing to validate performance under specified environmental conditions.

Single Zener Diodes Selection Notes

Select this component when a robust 10 W voltage regulation solution is needed for space-constrained or high-vibration environments. The stud-mount configuration facilitates direct heat sinking to chassis structures. Consider the 4.7 V output level and low impedance characteristics for precise reference applications requiring stable performance over wide thermal ranges.

Single Zener Diodes Part Context

This device belongs to the 1N3993A through 1N3998A series of 10 W Zener diodes manufactured by Microchip Technology. These components are designed for high-reliability applications where standard commercial parts may fail. The series offers various voltage options while maintaining consistent mechanical and electrical specifications across the product line.

Single Zener Diodes Replacement Considerations

Equivalent parts include the JAN1N3995A and JANTXV1N3995A variants, which share identical electrical parameters but differ in qualification levels. Verify pinout compatibility and thermal resistance values before substituting.
