Single Zener Diodes Procurement Notes

Verify authenticity by purchasing directly from Micro Commercial Components or authorized distributors to avoid counterfeit parts. Confirm that the specific suffix matches the required packaging format, such as tape and reel or bulk, as these affect handling and quantity per unit. Ensure compliance with RoHS standards if applicable to the project requirements.

Single Zener Diodes Selection Notes

Select this component based on the required 28.5V nominal breakdown voltage and the 500mW power dissipation limit. Consider the DO-35 through-hole package constraints and the operating temperature range up to 175°C. Evaluate the dynamic impedance and leakage current specifications against circuit sensitivity 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 voltage range from 1.8V to 47V, all sharing similar mechanical and thermal characteristics within the DO-35 package family.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N4120 equivalents in the DO-35 package. Verify that replacement parts meet the same 500mW power rating, 28.5V nominal voltage, and ±5% tolerance specifications.
