MMBT2222ALT1G
by onsemi(安森美)The MMBT2222ALT1G from onsemi is an NPN bipolar transistor for general-purpose switching and amplification. It fits discrete stages such as a logic-controlled load switch or a signal buffer, where a base drive network sets the operating point. The surface-mount SOT-23 package keeps the device practical for compact boards. Free downloadable KiCad files include a three-pin symbol, the three-pad SOT-23-3_L2.9-W1.3-P1.90-LS2.4-BR footprint, and a 3D model. These files come from a real ProtoFlow import that was converted and checked in the editor. Open the part directly in ProtoFlow to place it in a schematic and continue the board design.
