SMF7.5AQ
Yangzhou Yangjie Elec Tech · ESD And Surge Protection (TVS/ESD) · SOD-123FL
SMF7.5AQ from Yangzhou Yangjie Elec Tech, in a SOD-123FL. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | K | passive | Cathode of the unidirectional TVS, marked by the band on the package; connect to the protected positive line (VRWM 7.5 V, breakdown 8.33 V min to 9.21 V max at 1 mA). |
| 2 | A | passive | Anode of the unidirectional TVS, the end opposite the cathode band; connect to ground or the return line (clamping 12.9 V max at IPP 15.50 A). |
