Single Zener Diodes Procurement Notes

Verify the specific manufacturer designation, as this component is produced by multiple entities including Microsemi and Tak Cheong under similar part numbers. Confirm lead material composition and RoHS compliance status directly with the supplier, as variations exist between tin/lead and lead-free versions. Ensure the DO-35 package and hermetic seal requirements match the application specifications before procurement.

Single Zener Diodes Selection Notes

Select this component when a 18 V Zener reference with low leakage and high thermal stability is required. The DO-35 package supports through-hole mounting, while the 500 mW rating allows for moderate power handling. Verify that the 21 Ω impedance meets the noise and regulation requirements of the target circuit design.

Single Zener Diodes Part Context
