• Overvoltage protection

Single Zener Diodes Procurement Notes

Verify the specific suffix R1 against official documentation to confirm reel packaging specifications. Confirm RoHS compliance status through manufacturer datasheets or certificates. Ensure the ordering part number matches the exact electrical parameters required for the design, as variations exist within the series.

Single Zener Diodes Selection Notes

Select this component when a 20 V Zener voltage is required in a compact SMD form factor. The 200 mW power rating suits low-power signal conditioning tasks. Verify that the 25 Ohm impedance meets circuit requirements. Consider thermal derating curves if operating near maximum junction temperatures.

Single Zener Diodes Part Context

This part belongs to the MMSZ5229AS series, which covers Zener voltages from 4.3 V to 51 V. All devices in this series share identical mechanical dimensions and power dissipation ratings while varying in electrical breakdown characteristics. The AS suffix indicates the specific SOD-323 package variant.

Single Zener Diodes Replacement Considerations

MMSZ5250AS_R2_00001 is a verified substitute offering identical electrical specifications but packaged on a 12K reel instead of a 5K reel.
