SS1045CG is a 45V, 10A Schottky rectifier in an SMC package. Finding a replacement requires matching the package and current, while carefully checking the forward voltage (Vf) to manage power dissipation.

AI replacement insight

Electrical riskmedium

Higher Vf increases power loss. Requires thermal validation.

Package risklow

Candidates share the same SMC package footprint.

Can it be replaced directly?

No direct drop-in replacement is confirmed. All suitable candidates have a higher forward voltage (Vf), which impacts efficiency and thermal performance.

Best replacement path

Upgrade to a 60V rated part like SS1060 or SK106C. This provides a voltage margin, but you must validate the higher forward voltage in your design.

Main risk

Increased power dissipation and heat due to higher forward voltage (Vf) in all available alternatives.
