Package: SOD-123FYangjie TechnologyTVS - DiodesSeries: SMFPackage: Tape & Reel (TR)Type: ZenerVoltage - Reverse Standoff (Typ): 6VVoltage - Breakdown (Min): 6.67V

SMF6.0A is a widely available 200W, 6V unidirectional TVS diode in a compact SOD-123FL package, used for protecting sensitive electronics from voltage transients.

AI replacement insight

Package riskhigh

Selecting a non-SOD-123FL part requires a PCB redesign.

Electrical riskhigh

Incorrect polarity or voltage will lead to circuit malfunction or damage.

Sourcing risklow

The part is widely multi-sourced, making it easy to find.

Can it be replaced directly?

Direct replacement for SMF6.0A should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Source SMF6.0A from an alternate manufacturer like Littelfuse, Vishay, or GOODWORK.

Main risk

The main risk is selecting a part with a different package (e.g., SMB, SMA) or incorrect polarity (bidirectional), which would not be a drop-in replacement.
