Single Zener Diodes Procurement Notes

Verify the specific suffix designation when ordering, as variations such as JAN or JANTX indicate different qualification levels under MIL-PRF-19500/115. Confirm that the required package type matches the intended PCB layout, as axial leads are standard for this series. Ensure thermal management strategies account for the specified derating curve above 95°C to maintain safe operating limits during high-power scenarios.

Single Zener Diodes Selection Notes

Select this component when a robust 110 V regulation point is needed in harsh environments. The wide operating temperature range makes it suitable for aerospace or industrial settings where standard commercial parts may fail. Consider the 450 Ohm impedance value for noise sensitivity requirements in the target circuit design. Verify compatibility with existing mounting hardware due to the specific dimensions of the DO-41 package.

Single Zener Diodes Part Context

This part belongs to the 1N3016B-1 through 1N3045B-1 series of 1-watt Zener diodes manufactured by Microchip Technology.
