Single Zener Diodes Procurement Notes

Verify component authenticity and datasheet revision status before procurement. Confirm that the specific ordering suffix matches required plating specifications, as standard variants may differ from lead-free or tin/lead options. Check for End-of-Life notices regarding availability and last-time buy dates. Ensure compliance with environmental regulations applicable to the intended deployment region.

Single Zener Diodes Selection Notes

Select this component when a 110 V Zener reference is required in a DO-35 package. Consider the 750 Ω impedance and positive temperature coefficient for thermal stability requirements. Evaluate the 500 mW power rating against expected operating currents. Verify that the axial lead configuration fits the target PCB layout constraints.
