MPSA42
by BLUE ROCKET(蓝箭)MPSA42 is a three-lead transistor from BLUE ROCKET for circuits that need a discrete switching or amplification device. This listing uses a through-hole TO-92 form, so the physical lead arrangement matters when moving from schematic to board. The KiCad download contains a three-pin symbol, a three-pad TO-92-3_L4.8-W3.7-P2.54-R footprint, and a 3D model. It originated as a real ProtoFlow import; the conversion was checked in the editor. Check the symbol's pin assignments against your circuit before routing. The part can also be opened directly in ProtoFlow.
