SMBJ18A
by GOODWORK(固得沃克)
The GOODWORK SMBJ18A is a surface-mount transient voltage suppressor diode used to protect a circuit from voltage transients. Its two-terminal SMB package makes it suitable for a protection position on a PCB. The downloadable KiCad files include a two-pin symbol, the two-pad SMB_L4.4-W3.6-LS5.4-RD footprint, and a 3D model for checking the board layout. Check the diode orientation against the intended circuit when placing it. These files originated in a real ProtoFlow import, and the conversion was checked in the editor. The part can be opened directly in ProtoFlow.
