SMF150A from SUNMATE Elec, 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 (positive end, marked by color band) of the unidirectional SMF150A TVS, with 150 V stand-off voltage, 167-185 V breakdown at 1.0 mA and 243 V maximum clamping voltage. |
| 2 | A | passive | Anode of the unidirectional SMF150A TVS, the opposite terminal from the banded cathode, for 200 W (10/1000 µs) peak pulse power. |
