Best Alternatives to SI2306

Package: SOT-23GOODWORKMOSFETs - SingleDrain-Source Voltage (VDS): 30 VContinuous Drain Current (ID): 3.16 ADrain-Source On-Resistance (RDS(on)): 47 mΩ @ 10VGate-Threshold Voltage (VGS(th)): 1.0 V - 3.0 VTotal Power Dissipation (PD): 0.75 W

SI2306 alternatives should be checked as 30V N-channel SOT-23 MOSFETs. Pinout evidence is missing, so review is required before use.

AI replacement insight

Electrical riskmedium

30V candidates lack extra voltage margin.

Package risklow

kept candidates are SOT-23.

Firmware risklow

discrete MOSFET; no firmware.

Sourcing riskmedium

AO3400A lifecycle data conflicts.

Can it be replaced directly?

No verified pin-compatible replacement is proven from the provided fields.

Best replacement path

Start with AO3400A, AO3400C, or AO3480C, then verify pinout and gate-drive losses.

Main risk

Unverified pinout plus equal or lower voltage margin.
