Littelfuse · ESD And Surge Protection (TVS/ESD) · SOT-23
SM24CANB-02HTG from Littelfuse, 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 | Pin 1 (CAN line I/O) | bidirectional | Protected CAN bus line; clamps to Pin 3 with a 24.0 V reverse standoff voltage, 26.7 V minimum breakdown at 1 mA, and 50 V clamp at 10 A (8/20 µs). |
| 2 | Pin 2 (CAN line I/O) | bidirectional | Protected CAN bus line; clamps to Pin 3 with a 24.0 V reverse standoff voltage, 26.7 V minimum breakdown at 1 mA, and 50 V clamp at 10 A (8/20 µs). |
| 3 | GND | power_in | Common reference pin to which Pin 1 and Pin 2 are clamped; the datasheet specifies all clamp, leakage and capacitance parameters as Pin 1 or Pin 2 to Pin 3. |
