Find and compare replacements for the SMF6.0A-MS, a 6.0V unidirectional TVS diode in a SOD-123FL package. This guide helps you evaluate alternatives based on critical parameters like polarity, voltage, and current ratings.

AI replacement insight

Electrical riskhigh

Using a bidirectional part or one with incorrect voltage/current ratings can lead to circuit failure.

Package risklow

Most alternatives use the same SOD-123FL package, ensuring physical compatibility.

Can it be replaced directly?

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

Best replacement path

KPTVS6V0S1UR by KUU is the strongest candidate, matching the package, unidirectional polarity, 6.0V standoff voltage, and 19.4A peak current rating.

Main risk

The primary risk is selecting a bidirectional part (like an 'SMF6.0CA') instead of the required unidirectional 'SMF6.0A'. This can affect circuit behavior.
