SM24.N from BORN, 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 | 1 | bidirectional | Protected line of the ESD diode array, rated for 24 V reverse stand-off (VRWM) with 26.7 to 34.0 V breakdown (VBR at 1 mA), and junction capacitance of 30 typ / 35 max pF to pin 3 at VR = 0 V, 1 MHz. |
| 2 | 2 | bidirectional | Protected line of the ESD diode array, rated for 24 V reverse stand-off (VRWM) with 26.7 to 34.0 V breakdown (VBR at 1 mA), and junction capacitance of 30 typ / 35 max pF to pin 3 at VR = 0 V, 1 MHz. |
| 3 | 3 | passive | Common terminal of the diode array; the datasheet specifies the junction capacitance as pin 1 and pin 2 to pin 3, and does not name it as ground. |
