# SP1233-01ETG

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

SP1233-01ETG 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 | PIN 1 | passive | Pin 1 is shown on the pinout diagram of the bidirectional TVS diode, which protects each I/O pin against ESD at ±30kV contact discharge per IEC 61000-4-2. |
| 2 | PIN 2 | passive | Pin 2 is shown on the pinout diagram of the bidirectional TVS diode, which protects each I/O pin against ESD at ±30kV contact discharge per IEC 61000-4-2. |
