SD103AWS-TP is a 40V, 350mA Schottky diode in a compact SOD-323 package, widely used for fast switching and rectification. This page reviews and compares potential alternatives to help you find a suitable replacement.

AI replacement insight

Electrical riskmedium

Many alternatives have higher reverse leakage (Ir) or different forward voltage (Vf) curves.

Package risklow

SOD-323 is a standard package, but watch for flat-lead (F) variants that may have a different footprint.

Sourcing risklow

This is a common diode type available from many manufacturers, reducing single-source dependency.

Can it be replaced directly?

Yes, parts like SD103AWS from other manufacturers and BAT48JFILM are strong candidates for a pin-compatible replacement after datasheet verification.

Best replacement path

For a direct replacement, use other SD103AWS variants or BAT48JFILM. For higher power, SK16D3 is an option but requires reviewing its higher leakage.

Main risk

The main risk when substituting is an increase in reverse leakage current (Ir) or forward voltage drop (Vf), which can affect power efficiency and circuit behavior.
