BAV99T-7-F is a popular 85V dual switching diode in a compact SOT523 package. Finding a direct drop-in replacement requires matching the package, pinout, and key electrical ratings.

AI replacement insight

Electrical riskhigh

Candidates have lower voltage or different diode technology.

Package riskhigh

One candidate has a different package, requiring a PCB redesign.

Firmware risklow

Not applicable for this discrete component.

Can it be replaced directly?

Direct replacement for BAV99T-7-F should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

No direct replacement found. For a new layout, BAV199-7-F is a functional match. For an existing layout, BAT54ST-7-F is a high-risk option only if the circuit voltage is well below 30V.

Main risk

The primary risks are package incompatibility and insufficient voltage rating in proposed alternatives.
