LM-SM712 from Leiditech, in a SOT-23. 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 | PIN1 | passive | Protected line (I/O) per the datasheet's Pin1-or-Pin2-to-Pin3 ratings: reverse stand-off 12.0 V, breakdown 13.3 to 16.3 V at IR = 1 mA, reverse leakage 1.0 uA at VRWM = 12 V, and clamping voltage 24.0 V at IPP = 17 A. |
| 2 | PIN2 | passive | Protected line (I/O) with the same Pin1-or-Pin2-to-Pin3 limits: reverse stand-off 12.0 V, breakdown 13.3 to 16.3 V at IR = 1 mA, reverse leakage 1.0 uA at VRWM = 12 V, and clamping voltage 24.0 V at IPP = 17 A. |
| 3 | PIN3 | passive | Common terminal for the clamp ratings: reverse stand-off 7.0 V (Pin3-to-Pin1 or Pin2), breakdown 7.5 to 9.8 V at IR = 1 mA, reverse leakage 1.0 uA at VRWM = 7 V, and clamping voltage 18.0 V at IPP = 22 A. |
