# SP1001-02JTG

**Littelfuse** · ESD And Surge Protection (TVS/ESD) · SC-70-3

SP1001-02JTG from Littelfuse, in a SC-70-3. 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 | ESD-protected I/O line 1 (Zener diode anode to pin 3 ground), protected to ±15kV contact and ±30kV air per IEC 61000-4-2 with 8pF typical capacitance. |
| 2 | I/O2 | passive | ESD-protected I/O line 2 (Zener diode anode to pin 3 ground), protected to ±15kV contact and ±30kV air per IEC 61000-4-2 with 8pF typical capacitance. |
| 3 | GND | power_in | Common ground connection of the diode array, to which both I/O protection diodes return. |
