Single Zener Diodes Procurement Notes

Verify the specific suffix code on the component marking to confirm the exact package type and tolerance level, as the base part number covers multiple variants. Confirm RoHS compliance status based on the manufacturer's current production batch, as older or military-grade versions may differ. Ensure the selected variant matches the required thermal management capabilities for the intended operating environment.

Single Zener Diodes Selection Notes

Select the appropriate package style based on the board layout constraints, choosing between surface mount DO-213AB or through-hole DO-7 configurations. Evaluate the circuit's thermal requirements to ensure the 500 mW power rating is sufficient under worst-case conditions. Consider the 75 V Zener voltage and its temperature coefficient when designing precision reference applications requiring stability over wide temperature ranges.
