SP3003-04JTG from Littelfuse, in a SC-70-6. 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/O 1 | passive | ESD-protected signal line with ultra-low-capacitance rail-to-rail diodes and a zener clamp, rated for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 with 0.65 pF typical I/O capacitance. |
| 2 | GND | power_in | Ground reference for the protection diodes; the datasheet specifies no separate limit for this pin. |
| 3 | I/O 2 | passive | ESD-protected signal line with ultra-low-capacitance rail-to-rail diodes and a zener clamp, rated for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 with 0.65 pF typical I/O capacitance. |
| 4 | I/O 3 | passive | ESD-protected signal line with ultra-low-capacitance rail-to-rail diodes and a zener clamp, rated for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 with 0.65 pF typical I/O capacitance. |
| 5 | VCC | power_in | Supply connection for the protection device; the datasheet characterises capacitance at VCC = 3.3 V, 5 V and floating but states no VCC voltage limit. |
| 6 | I/O 4 | passive | ESD-protected signal line with ultra-low-capacitance rail-to-rail diodes and a zener clamp, rated for ±8 kV contact and ±15 kV air discharge per IEC 61000-4-2 with 0.65 pF typical I/O capacitance. |
