AI Summary

MMSZ4680T1 by onsemi: Zener Diode 2.2 V 500 mW ±5% Surface Mount SOD-123.

This is the official, direct, and active RoHS-compliant replacement part from onsemi. It offers identical electrical parameters and the same physical pin assignment, making it a seamless drop-in alternative.

  • Direct RoHS-compliant replacement from the original manufacturer (onsemi)
  • Identical electrical characteristics: 2.2V nominal Zener voltage, 500mW power rating, and 4 µA reverse leakage at 1V
  • Perfect pin-for-pin drop-in compatibility (Pin 1: Cathode, Pin 2: Anode)

This is the automotive-grade version of the direct RoHS-compliant replacement. It is highly recommended for designs requiring AEC-Q101 qualification or operating in harsh environments.

  • AEC-Q101 qualified for high-reliability and automotive applications
  • Provides PPAP capability and enhanced quality controls
  • Identical electrical specs and pin assignments to the original part
  • Typically has a higher unit cost compared to standard commercial-grade parts.

You searched one part. Parter watches your whole BOM.

  1. All your BOM, at once

    Parter maps every line to live stock, lead time, lifecycle and compliance data across the entire market — not part by part.

  2. Hear about problems before they hit production

    Allocation, EOL and last-time-buy notices surface the moment they appear, not when your buyer's PO bounces.

  3. Qualified replacements in minutes, not days

    Every at-risk line gets form-fit-function matches like the ones above — deltas flagged, evidence attached. Review, push to your BOM, and Parter starts watching the new part too.

Frequently asked questions

Yes. The onsemi MMSZ4680T1 is marked obsolete, so the manufacturer has discontinued it and any remaining supply is limited to distributor stock. The qualified second sources on this page are active parts you can design in today.
