SP1305-02HTG 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 | passive | Protected line 1 (Pin1 to Pin3) with 5V reverse standoff, 6V min/7V max breakdown at 1mA, and ±30kV contact/air ESD withstand per IEC 61000-4-2. |
| 2 | I/O2 | passive | Protected line 2 (Pin2 to Pin3) with 5V reverse standoff, 6V min/7V max breakdown at 1mA, and ±30kV contact/air ESD withstand per IEC 61000-4-2. |
| 3 | GND | power_in | Common reference pin to which Pin1 and Pin2 are measured; I/O-to-GND capacitance is 30pF typ (40pF max) at 0V bias, 1MHz. |
