Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as Microsemi and other entities produce identical part numbers. Confirm RoHS compliance status, noting that some variants like the D suffix may be non-compliant. Ensure the DO-35 package matches the design requirements before procurement.

Single Zener Diodes Selection Notes

Select this component for through-hole designs requiring robust thermal performance up to 200°C. The 8.2 V rating suits mid-range regulation needs. Verify tolerance requirements, as standard versions typically offer 5% or 10% accuracy depending on the specific suffix.

Single Zener Diodes Part Context

This device belongs to the 1N5221 through 1N5267 series of 500 mW Zener diodes. The series offers a wide voltage selection from 2.4 to 75 volts. These components are widely used in general-purpose electronics for their reliability and standardized DO-35 footprint.

Single Zener Diodes Replacement Considerations

Equivalent parts include 1N5237B and 1N5237BT. Check suffixes for tolerance variations and packaging differences such as bulk versus reel configurations.
