Single Zener Diodes Procurement Notes

Verify the specific qualification level (JAN, JANTX, JANTXV, or JANS) required for your application, as the base part number covers multiple reliability grades. Confirm RoHS compliance status if applicable, noting that compliant versions are typically commercial grade only. Ensure the ordering suffix matches the desired tolerance and packaging configuration.

Single Zener Diodes Selection Notes

Select this component when a precise 8.2 V reference with tight ±1% tolerance is needed in a ruggedized environment. The low dynamic impedance of 0.5 Ohms makes it suitable for stable regulation under varying load conditions. Consider the thermal derating curve for power dissipation limits above 25°C lead temperature.

Single Zener Diodes Part Context
