Single Zener Diodes Procurement Notes

Verify the specific reliability level required, as the part is available in JAN, JANTX, JANTXV, and JANS qualifications. Confirm RoHS compliance status, noting that commercial versions may differ from mil-qualified units. Ensure the metallurgically bonded suffix (-1) is included if required by the design specifications.

Single Zener Diodes Selection Notes

Select this component for applications requiring stable voltage regulation in harsh environments. The low dynamic impedance supports precise regulation. Consider the thermal resistance values when designing heat dissipation strategies. Verify lead plating options against soldering requirements.

Single Zener Diodes Part Context

This device belongs to the 1N4099 through 1N4135 series of 500 mW Zener voltage regulators. The series offers voltages from 1.8 to 100V with various tolerance options. These components are designed for robust performance in demanding electronic systems.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 16V nominal voltage, 0.5W power rating, and DO-35 package. Verify equivalent MIL-PRF-19500/435 qualification levels if high reliability is required.
