Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required reliability level (JAN, JANTX, JANTXV, or JANS) and voltage tolerance. Confirm RoHS compliance status if applicable, noting that commercial versions may differ from military specifications. Ensure the package type aligns with the design requirements before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for designs requiring strict adherence to MIL-PRF-19500/533 standards. Consider the thermal resistance values when calculating power derating curves for your specific mounting conditions. Verify that the 8.2 V breakdown voltage fits the circuit's regulatory needs without exceeding the maximum surge current limits.
