S2M is a 1000V 2A SMA general rectifier. The closest catalog candidate found is S3MA, but pinout and datasheet checks are still required.

AI replacement insight

Electrical riskmedium

1000V candidates lack 1.1x margin.

Package risklow

SMA package is listed.

Firmware risklow

No firmware interface.

Sourcing riskmedium

Lifecycle fields are sparse.

Can it be replaced directly?

No verified pin-compatible replacement is confirmed from the provided fields.

Best replacement path

Review S3MA first; verify polarity, package drawing, and ratings.

Main risk

Pinout evidence and voltage margin are incomplete.
