Single Zener Diodes Procurement Notes

Verify the specific manufacturer source, as this part number appears in listings from multiple vendors including Microchip and onsemi. Confirm RoHS compliance status and exact datasheet revision before procurement, as specifications may vary between manufacturers offering equivalent part numbers. Ensure the package type matches the required PCB footprint.

Single Zener Diodes Selection Notes

Select this component when a 3.9 V reference is needed in a through-hole configuration. Consider the 500 mW power limit and 23 Ohm impedance for circuit stability. Verify thermal management requirements given the wide operating temperature range. Compare against alternative manufacturers if supply chain diversity is required.

Single Zener Diodes Part Context

This component belongs to the standard 1N52xx series of Zener diodes, widely used for voltage regulation. The DO-35 package is a common industry standard for low-power axial components. Equivalent parts exist from various semiconductor manufacturers, often sharing identical electrical parameters but differing in packaging or screening levels.

Single Zener Diodes Replacement Considerations

Direct substitutes include 1N5228B from Microchip Technology and MV1N5228BTR-1 from Microsemi. These alternatives share the same 3.9 V Zener voltage and DO-35 package form factor. Verify pinout compatibility and thermal ratings before substitution.
