Single Zener Diodes Procurement Notes

Verify component authenticity by checking for authorized distributor sourcing, as counterfeiting is a noted industry risk. Confirm RoHS compliance status via official documentation, noting that specific suffixes may indicate material variations. Ensure the procurement channel provides full traceability and meets quality standards for handling and storage to guarantee genuine parts.

Single Zener Diodes Selection Notes

Select this component when a precise 62 V regulation point is required in through-hole designs. The DO-41G package accommodates standard PCB mounting techniques. Verify thermal derating requirements if operating above 50°C ambient conditions. Consider the 125 Ω dynamic impedance for noise-sensitive applications requiring stable voltage clamping.

Single Zener Diodes Part Context

This part belongs to the 1N4728 through 1N4761 series of 1 Watt Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V. The 'A' suffix indicates a 5% voltage tolerance, distinguishing it from standard or tighter tolerance variants within the same family.

Single Zener Diodes FAQ

What is the maximum forward voltage drop?

The maximum forward voltage drop is 1.2 V at a forward current of 200 mA.

How is the Zener impedance measured?

It is derived from the 60 Hz AC voltage resulting when an AC current equal to 10% of the DC Zener current is superimposed on the DC bias.
