Best Alternatives to MDD2302

Package: SOT-23MDD(Microdiode Semiconductor)MOSFETs - SingleDrain-Source Voltage (VDS): 20 VContinuous Drain Current (ID): 4 ARDS(on) @ 4.5V: 25 mΩRDS(on) @ 2.5V: 28 mΩGate Threshold Voltage (VGS(th)): 0.8 V

MDD2302 is a 20V N-channel SOT-23 MOSFET. Available candidates need pinout, voltage margin, and derating checks.

AI replacement insight

Electrical riskhigh

VDS margin and PD must be checked.

Package riskmedium

SOT-23 matches, pinout is missing.

Firmware risklow

Discrete MOSFET; no firmware.

Sourcing riskhigh

Closest candidate is obsolete.

Can it be replaced directly?

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

Best replacement path

Use only N-channel SOT-23 MOSFETs with verified pinout and equal or better VDS, RDS(on), PD, and Qg.

Main risk

Missing pinout and limited voltage or power margin.
