**TECH PUBLIC** · ESD Protection Devices · SOT-23

SM24CANA-02HTG from TECH PUBLIC, 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 | I/O1 | passive | Protected line 1 of the 2-line bi-directional TVS array, with a 24V reverse working voltage (max) and a junction capacitance of 7 pF typ to pin 2. |
| 2 | I/O2 | passive | Protected line 2 of the 2-line bi-directional TVS array, with a 24V reverse working voltage (max) and a junction capacitance of 7 pF typ to pin 1. |
| 3 | COM | passive | Common node of the steering diodes, tied internally to the TVS junction. Capacitance from pin 3 to pin 2 is 10 pF typ and 18 pF max. |
