The 1SS355 is a popular 80V, 100mA fast switching diode in a SOD-323 package, used in high-speed signal applications. Several pin-compatible alternatives like the BAS316 and 1N4148WS exist with similar or better performance.

AI replacement insight

Electrical risklow

Low when using pin-compatible parts like BAS316, but high if a slower diode is chosen.

Package risklow

All strong candidates use the same SOD-323 package, ensuring form and fit compatibility.

Sourcing risklow

Strong alternatives like BAS316 and 1N4148WS are common, multi-sourced components.

Can it be replaced directly?

Direct replacement for 1SS355 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

BAS316 offers a direct upgrade path with higher voltage and current ratings while matching the critical package and switching speed.

Main risk

The main risk is selecting a part with a slower reverse recovery time (Trr), which can degrade performance in high-speed switching applications.
