Single Zener Diodes Procurement Notes

Verify the authenticity of the component by checking for authorized distributor sourcing. Confirm the specific suffix (TP) corresponds to tape and reel packaging containing 10,000 pieces per reel. Ensure compliance with RoHS3 standards and check for any relevant PCN regarding manufacturing changes or obsolescence status before finalizing procurement plans.

Single Zener Diodes Selection Notes

Select this component when a 47V Zener voltage with tight ±5% tolerance is required in a through-hole DO-35 package. Consider the 500mW power dissipation limit and the 175°C maximum junction temperature for thermal management. Verify that the 250 Ohm maximum dynamic impedance meets the circuit's noise and stability requirements.

Single Zener Diodes Part Context

This part belongs to the 1N4614 through 1N4125 series of 500mW Silicon Zener Diodes manufactured by Micro Commercial Components. The series covers a wide Zener voltage range from 1.8V to 47V. All devices in this family share the same DO-35 glass package and mechanical construction specifications.
