Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., -1, BUR) against the datasheet to confirm tolerance and packaging variations. Confirm RoHS compliance status as standard versions may not meet current directives. Validate that the required operating temperature range aligns with the component's specified limits before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when an 82 V regulation point is required in a through-hole design. Ensure the circuit current does not exceed the 500 mW power dissipation limit at the expected ambient temperature. Consider the 330 Ohm impedance for noise-sensitive applications requiring tighter regulation stability.
