Finding a substitute for the BAS70H,115 Schottky diode involves matching the SOD123F package, 70V reverse voltage, and low forward voltage. Key alternatives exist but require checking electrical differences.

AI replacement insight

Electrical riskmedium

Forward voltage (Vf) and reverse leakage (Ir) can vary significantly between alternatives.

Package risklow

SOD123F is a common package with many available parts.

Sourcing risklow

General-purpose Schottky diodes are widely available from multiple manufacturers.

Can it be replaced directly?

Direct replacement for BAS70H,115 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

The most promising path is BAT46WH,115, which matches the package and diode type while offering improved voltage and current ratings. A review of its higher leakage current is the only major checkpoint.

Main risk

The main risk is substituting with a standard switching diode (like BAS16H/BAS21H) instead of a Schottky, which results in a significantly higher forward voltage and increased power dissipation.
