Single Zener Diodes Procurement Notes

Verify that the specific order includes the JANS or JAN prefix if military qualification is required, as standard commercial variants lack this certification. Confirm RoHS status, as military parts often do not comply. Ensure the DO-41 through-hole package matches the PCB footprint requirements. Validate the ±1% tolerance requirement against circuit design specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when strict voltage accuracy and military reliability are mandatory. The DO-41 package requires through-hole assembly, which may limit use in high-density surface-mount designs. Consider the 1.5 W power rating for thermal management needs. Verify compatibility with operating temperatures up to 175°C for extreme environment applications.
