Single Zener Diodes Procurement Notes

Verify the specific suffix requirements when ordering, as the base model number may correspond to different packaging or qualification levels. Confirm that the DO-213AA package matches your PCB layout constraints. Ensure compatibility with RoHS directives if required by your project specifications, noting that some variants may have specific compliance statuses.

Single Zener Diodes Selection Notes

Select this component when a 56 V reference point is required in a small surface mount form factor. Consider the 500 mW power rating against expected operating conditions. Evaluate the thermal management capabilities of the target application given the wide operating temperature range. Compare impedance characteristics against other Zener diodes in the same voltage class for noise sensitivity requirements.
