| FFF Compatibility | Pinout and footprint are identical, featuring the standard SOT-23 dual series configuration.Utilizes the standard SOT-23-3 (TO-236AB) surface mount package matching the original's dimensions.Meets or exceeds all electrical parameters, providing a higher forward current (300mA vs 215mA) and matching 75V reverse voltage. | The physical footprint and the standard 3-pin configuration are a direct match.Standard SOT-23 package with identical mechanical drawing dimensions.Upgrades the maximum DC reverse voltage to 100V while matching the 215mA average rectified current rating. | ||
 AI Summary | BAV99 by onsemi: Diode Array 1 Pair Series Connection 75 V 215mA Surface Mount TO-236-3, SC-59, SOT-23-3. | The BAV99-7-F from Diodes Incorporated serves as an excellent drop-in replacement. It offers a higher rectified forward current rating of 300 mA (compared to the target's 215 mA) while maintaining the identical 75 V DC reverse voltage and 4 ns fast switching speed.
| The onsemi BAV99LT1G is a highly reliable alternative from a top-tier manufacturer. It provides a higher reverse voltage headroom of 100 V, though it has a slightly slower reverse recovery time of 6 ns compared to the original 4 ns.

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 onsemi BAV99 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 onsemi BAV99 are the BAV99-7-F (Diodes Incorporated) and the BAV99LT1G (onsemi), out of 6 matched alternatives in total. Each is compared against the original on fit, form and function in the table above.
Yes. The leading alternatives to the BAV99 are fit-, form- and function-compatible — the same package and pinout with matching key electrical specifications — so they drop in without PCB changes. Always confirm the parameters critical to your design against the alternative's datasheet before committing.
The BAV99 (onsemi) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
