What risks should I check before replacing SS26T3G?

The main risk is substituting a standard or 'ultrafast' diode for the Schottky type, which causes much higher forward voltage (Vf) and power loss. Always verify the substitute's Vf and reverse leakage current (Ir) are acceptable for your circuit.

SS26T3G Alternatives, Datasheet & Cross Reference | onsemi

SS26T3G is a 60V, 2A Schottky rectifier in a standard SMB package, valued for its low forward voltage and efficiency. Finding a replacement requires matching the Schottky technology and key electrical ratings to ensure thermal stability and performance.

AI replacement insight

Electrical riskhigh

Using a part with higher Vf will increase power dissipation and may lead to thermal failure.

Package risklow

The SMB (DO-214AA) package is standardized, making physical replacement straightforward.

Can it be replaced directly?

Direct replacement for SS26T3G should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Use a Schottky diode in an SMB package with ratings of at least 60V and 2A. MBRS360BT3G is an excellent upgrade path from the same manufacturer.

Main risk

The primary risk is substituting with a non-Schottky (e.g., 'Ultrafast') diode, which will have a much higher forward voltage (Vf), causing overheating.

Recommended alternatives

An upgrade from the same manufacturer with a higher 3A current rating and matching package and voltage.
