Overview

The MMBT4401 is a bipolar made by onsemi in a SOT-23 package with 3 pins. -55℃~+150℃ 100nA 250MHz 350mW 400mV 40V 600mA 6V NPN SOT-23 Bipolar (BJT) ROHS.

PCBKit's library has its KiCad symbol (dk_Transistors-Bipolar-BJT-Single:MMBT4401_Obsolete, from Digikey) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C236941).
