Single Zener Diodes Procurement Notes

Verify authenticity through authorized MCC distributors due to counterfeiting risks. Confirm the -TP suffix indicates tape and reel packaging containing 10,000 pieces per reel. Ensure the component meets the specified lead-free and RoHS standards required for your assembly process. Check for any recent datasheet revisions that may affect electrical parameters or mechanical dimensions before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 17.85V reference is needed within a 500mW power dissipation limit. The DO-35 package suits applications requiring axial leads and compact board space. Consider the 21 ohm dynamic impedance for AC signal sensitivity. Verify thermal management capabilities given the 250°C/W junction-to-lead thermal resistance rating under specified lead length conditions.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4125 series of 500mW silicon Zener diodes. All devices in this family share identical mechanical housing and maximum ratings but vary in nominal Zener voltage from 1.8V to 47V. The series utilizes double slug construction and offers standard ±5% voltage tolerance across the entire range.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering 1N4617 equivalents in DO-35 packages. Ensure replacement parts match the 17.85V nominal voltage, 500mW power rating, and ±5% tolerance. Verify compatibility with existing PCB footprint and lead spacing requirements.
