Needs validationlow risk
A potential pin-compatible alternative from Nexperia in the same SOT-323 package with a higher voltage rating.
Best Alternatives to BAV70W
The BAV70W is a popular fast-switching dual diode in a compact SOT-323 package. When searching for replacements, focus on candidates with the same package, common cathode configuration, and similar or better electrical ratings.
AI replacement insight
Package riskmedium
Similar packages like SOT-23 have different footprints.
Electrical risklow
Many alternatives offer superior or matching electrical specs.
Can it be replaced directly?
Direct replacement for BAV70W should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Cross-reference to other manufacturers' BAV70W variants in the SOT-323 package, like Nexperia BAV70W,115.
Main risk
The main risk is assuming pin-compatibility without datasheet verification, or selecting a part with a different package or internal configuration.
