| FFF Compatibility | Features the identical Mini MELF (SOD-80) surface mount package with the same footprint and pin configuration (Cathode band / Anode).The physical dimensions and package type match the original SOD-80 / Mini MELF outline precisely.Shares the identical 12V Zener voltage and 500mW power rating, while offering superior leakage specifications. | Shares the identical SOD-80 / Mini MELF surface mount pattern and anode/cathode polarity markings.Standard Mini MELF glass package dimensions are functionally identical.Meets the 12V nominal Zener breakdown and 500mW dissipation ceiling with enhanced electrical parameters. | ||
 AI Summary | DL5242B by Diodes Incorporated: Zener Diode 12 V 500 mW ±5% Surface Mount Mini MELF. | The TZMC12-GS08 is an excellent, highly reliable active alternative from Vishay. It matches the original 12V zener voltage and 500mW power ratings while improving the leakage current spec to 100 nA max. It is AEC-Q101 qualified for enhanced reliability.
| The BZV55C12 L0G is a drop-in replacement that features lower dynamic impedance (20 Ohms vs 30 Ohms) and much tighter reverse leakage limits, making it a robust alternative for voltage regulation.

You searched one part. Parter watches your whole BOM.
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.
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.
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 Diodes Incorporated DL5242B 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.
The closest qualified second sources for the Diodes Incorporated DL5242B are the TZMC12-GS08 (Vishay General Semiconductor - Diodes Division) and the BZV55C12 L0G (Taiwan Semiconductor Corporation), out of 3 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Not always. The alternatives to the DL5242B are matched on function but can differ in package, pinout or a key parameter, so review the fit/form/function notes in the table and the datasheet before designing one in.
The DL5242B (Diodes Incorporated) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
