Is there a pin-compatible replacement for S3BB-13-F?

S3MB-13-F shares the same SMB package, pinout, and key electrical ratings, making it a likely pin-compatible replacement. Always verify the datasheet for your specific layout.

What risks should I check before replacing S3BB-13-F?

Key risks include mismatched diode technology (e.g., Schottky vs. standard), which affects reverse leakage and recovery time, and insufficient current or voltage ratings.

S3BB-13-F Alternatives, Datasheet & Cross Reference | Diodes Incorporated

S3BB-13-F is a 3A, 100V standard rectifier in a common SMB package, used for general-purpose rectification. Finding a suitable replacement involves matching the package, current, and voltage ratings.

AI replacement insight

Electrical risklow

Low if sticking to standard rectifiers with equal or better ratings.

Package risklow

Low, as SMB is a standard package.

Can it be replaced directly?

Yes, S3MB-13-F is a strong candidate for direct replacement, sharing the same package, current, and manufacturer family.

Best replacement path

S3MB-13-F offers a near-identical profile with an upgraded voltage rating, representing the lowest-risk path.

Main risk

The primary risk when substituting is using a diode with a different technology, like Schottky, which can increase reverse leakage current.

Recommended alternatives
