ZMM2V4
by ST(先科)For voltage-reference and limiting circuits, ZMM2V4 is a surface-mount Zener diode from ST(先科). Its LL-34 package uses two terminals, with anode and cathode orientation relevant to both schematic connections and PCB placement. The files originated in a real ProtoFlow import and were converted and checked in the editor. Available for free download, the KiCad assets include a two-pin symbol and the LL-34_L3.5-W1.5-RD footprint with two pads. A 3D model is also supplied for viewing the package in the assembled board. This diode can be opened directly in ProtoFlow for schematic capture and layout.
