# SC1333-01ETG

**Littelfuse** · ESD And Surge Protection (TVS/ESD) · SOD-882

SC1333-01ETG from Littelfuse, in a SOD-882. 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 | bidirectional | One side of the back-to-back TVS diode pair, rated for 3.3 V reverse standoff, 8 kV contact ESD per IEC 61000-4-2 (datasheet ESD rating ±30 kV), and 8 pF typical capacitance I/O to I/O. |
| 2 | I/O | bidirectional | Other side of the back-to-back TVS diode pair, providing symmetrical ESD protection for data lines with a 5 A 8/20 µs surge rating and 0.3 Ω typical dynamic resistance (TLP). |
