Needs validationlow risk
The base BAV99 is a widely sourced alternative with the same package and configuration, offering better current handling.
Best Alternatives to BAS70-04
BAS70-04 is a 70V, 70mA dual series switching diode in a SOT-23 package. Common alternatives include parts from the widely available BAV99 family, which typically offer similar or improved electrical characteristics in the same package.
AI replacement insight
Electrical risklow
Most alternatives offer higher current/voltage ratings, providing more design margin.
Package risklow
SOT-23 is a standard package, ensuring mechanical compatibility.
Sourcing risklow
The BAV99 family is a multi-source, high-volume commodity part, making it easier to source than the target.
Can it be replaced directly?
Direct replacement for BAS70-04 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
Use a BAV99 from a reputable manufacturer like onsemi, Nexperia, or Diodes Inc.
Main risk
The primary risk is a subtle difference in pinout, although SOT-23 series diodes are highly standardized. Always verify the datasheet.
