Single Zener Diodes Procurement Notes

Verify the specific suffix and manufacturing source when procuring, as variants such as JAN or JANTX may exist with different qualification standards. Confirm RoHS compliance status directly with the manufacturer, as certain military-grade versions may not meet standard environmental directives. Ensure the ordering part number matches the required package and tolerance specifications for your design.

Single Zener Diodes Selection Notes

Select this component when a reliable 8.2 V reference is needed in a small surface-mount footprint. Consider the 500 mW power rating and 200 Ohm impedance for circuit stability. Verify that the -65°C to +175°C temperature range meets your operational requirements compared to lower-grade alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N4101 series of Zener diodes manufactured by Microchip Technology. It shares the base 1N4101 designation but is packaged in the DO-213AA SMD format rather than traditional axial leads. This series is commonly used in industrial and aerospace electronics requiring robust voltage regulation.
