S1B-13-F is a standard 100V, 1A general-purpose rectifier in an SMA package. Finding a replacement involves matching the package and current, ensuring voltage is equal or greater, and checking recovery time and forward voltage.

AI replacement insight

Electrical riskmedium

Mismatched recovery time (trr) or forward voltage (Vf) can cause issues.

Package risklow

All candidates use the same SMA package.

Sourcing risklow

These are common rectifier diodes from a major manufacturer.

Can it be replaced directly?

Yes, S1D-13-F and S1G-13-F are direct, pin-compatible replacements for S1B-13-F with higher voltage ratings.

Best replacement path

Use a higher-voltage part from the same S1 series, like S1D-13-F or S1G-13-F, for a direct drop-in upgrade.

Main risk

The main risk is selecting a substitute with a different recovery speed (e.g., fast or ultra-fast) or a higher forward voltage (Vf), which can affect circuit performance and thermal management.
