Single Zener Diodes Procurement Notes

Verify the specific reliability level required (JAN, JANTX, JANTXV, or JANS) as these are distinct part numbers within the series. Confirm RoHS compliance status, noting that commercial versions may differ from military qualifications. Ensure the ordering suffix matches the desired termination plating and packaging configuration before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a stable 82 V reference is needed in harsh environments. The DO-35 package suits through-hole designs requiring robust mechanical mounting. Consider the positive temperature coefficient above 6.8 V for thermal stability requirements. Verify that the 500 mW power dissipation rating aligns with the circuit's thermal management capabilities.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener diodes manufactured by Microchip Technology. These components are JEDEC registered and designed for demanding applications requiring precise voltage regulation. The series offers various voltage options from 1.8 V to 100 V across different tolerance grades.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 82 V Zener voltage, 500 mW power rating, and DO-35 package. Verify equivalent MIL-PRF-19500/435 qualification if radiation hardness or high reliability is critical. Cross-reference dynamic impedance and leakage current specifications to ensure circuit compatibility.
