Littelfuse · ESD And Surge Protection (TVS/ESD) · SOT-23-3
SM05-02HTG from Littelfuse, in a SOT-23-3. 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 | bidirectional | Protected line that clamps to pin 3 at 9.8 V at 1 A and 13.0 V at 10 A (8/20 µs) for SM05, with a 5.0 V reverse standoff and ±30 kV IEC 61000-4-2 ESD withstand. |
| 2 | I/O2 | bidirectional | Protected line that clamps to pin 3 at 9.8 V at 1 A and 13.0 V at 10 A (8/20 µs) for SM05, with a 5.0 V reverse standoff and ±30 kV IEC 61000-4-2 ESD withstand. |
| 3 | GND | power_in | Common reference for both protected lines; the SM05 clamp conditions are specified from pin 1 or pin 2 to pin 3, with a maximum peak pulse current of 24.0 A (8/20 µs). |
