Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required qualification level and tolerance. Confirm RoHS compliance status as it varies by commercial grade availability. Ensure the ordering suffix correctly indicates tape and reel packaging if automated assembly is required. Cross-reference datasheet electrical limits against system operating conditions before procurement.

Single Zener Diodes Selection Notes

Select this component when a 25 V Zener reference with low dynamic impedance is required. The axial-lead DO-35 package facilitates through-hole mounting. Consider the positive temperature coefficient above 5.6 V for thermal stability analysis. Verify that the 500 mW power dissipation rating meets the thermal requirements of the target application environment.

Single Zener Diodes Part Context

This component belongs to the 1N4099-1 through 1N4135-1 series of 500 mZener diodes manufactured by Microchip Technology. The series offers voltages from 1.8 V to 100 V with various tolerance options.
