| FFF Compatibility | This is the direct Pb-free drop-in replacement in the identical SOT-23-3 package with the exact same common cathode pinout (Pin 1: Anode 1, Pin 2: Anode 2, Pin 3: Common Cathode).The SOT-23 package dimensions and mounting footprint are 100% identical.All electrical parameters, including the 50V breakdown voltage, 200mA rectified current, and 4ns switching speed, match the obsolete target part. | The part uses the standard SOT-23-3 package with the identical common cathode pinout (Pin 1: Anode 1, Pin 2: Anode 2, Pin 3: Common Cathode).The package and mechanical landing pattern are completely identical to the target.The critical reverse voltage (50V) and switching speed (4ns) match, while the current limit is slightly improved to 215mA. | ||
 AI Summary | BAV74 by Infineon Technologies: Diode Array 1 Pair Common Cathode 50 V 200mA Surface Mount TO-236-3, SC-59, SOT-23-3. | The BAV74LT1G is onsemi's direct lead-free (Pb-free) equivalent to the obsolete BAV74. It is currently active, widely stocked, and offers identical electrical ratings and physical SOT-23 pinout compatibility with zero redesign effort.
| Nexperia's BAV74,215 is an active, high-reliability direct second-source alternative for the BAV74. It maintains the identical electrical profile and physical footprint with a minor improvement in current capacity.

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 Infineon Technologies BAV74 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 Infineon Technologies BAV74 are the BAV74LT1G (onsemi) and the BAV74,215 (Nexperia USA Inc.), out of 5 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 BAV74 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 BAV74 (Infineon Technologies) is a part in the Diodes category. This page lists qualified, cross-referenced replacements for it with a side-by-side comparison.
