Single Zener Diodes Procurement Notes

Verify the specific reliability level (JAN, JANTX, JANTXV, or JANS) required for the application, as these levels are available per MIL-PRF-19500/435. Confirm RoHS compliance status if applicable, noting that compliant versions are available on commercial grade only. Ensure the ordering suffix matches the desired qualification and packaging configuration.

Single Zener Diodes Selection Notes

Select based on the required Zener voltage tolerance, which is available in 5%, 2%, and 1% options. Consider the operating temperature range and power dissipation requirements, ensuring linear derating is applied above 50°C lead temperature. Verify noise density specifications if low-noise performance is critical for the circuit design.
