BAT54CLT1G is a SOT-23 dual common-cathode Schottky diode. Alternatives must match topology, pinout, and low VF behavior.

AI replacement insight

Electrical riskhigh

Schottky VF behavior is critical.

Package risklow

Kept options are SOT-23.

Firmware risklow

Passive diode array.

Sourcing riskmedium

No verified drop-in listed.

Can it be replaced directly?

No direct pin-compatible replacement is verified from the provided data.

Best replacement path

Look for BAT54C-family Schottky parts with confirmed SOT-23 pinout.

Main risk

Using silicon switching diodes can raise clamp voltage.
