1N4744A
by onsemi(安森美)
For discrete voltage limiting and simple reference circuits, the onsemi 1N4744A is a Zener diode in an axial through-hole package. Its two-terminal arrangement requires attention to anode and cathode orientation when moving from the schematic to the board. Free KiCad files provide a 2-pin symbol and the DO-41_BD2.4-L4.7-P8.70-D0.9-RD footprint, which has 2 pads for the leads. A 3D model is also included for viewing the mounted component alongside surrounding parts. Real-design use supports the conversion: 1 ProtoFlow engineer has used it in their designs. The complete part can be opened directly in ProtoFlow.
