STTH112A is a 1200V, 1A ultrafast SMA rectifier. The reviewed candidates do not prove a direct pin-compatible replacement.

AI replacement insight

Electrical riskhigh

Most candidates are below 1200V or lack trr.

Package risklow

Several candidates share SMA.

Firmware risklow

No firmware interface.

Sourcing riskmedium

PDF checks are pending.

Can it be replaced directly?

No direct replacement is verified from the provided evidence.

Best replacement path

Use an equal or higher 1200V ultrafast SMA rectifier with confirmed trr and Tj.

Main risk

Lower voltage or missing recovery data can cause failure in high-voltage switching circuits.
