# SPHV24-01KTG

**Leiditech** · ESD And Surge Protection (TVS/ESD) · DFN1006-2

SPHV24-01KTG from Leiditech, in a DFN1006-2. 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 | 1 | passive | One of the two leadless terminals of the 1-line bi-directional TVS diode, which protects one data or power line with a 24 V working voltage (VRWM) and 300 W peak pulse power (8/20 µs). The datasheet does not name this terminal or state its polarity, as the terminal diagram is not reproduced in the text. |
| 2 | 2 | passive | The second of the two leadless terminals of the 1-line bi-directional TVS diode, which protects one data or power line with a 24 V working voltage (VRWM) and 300 W peak pulse power (8/20 µs). The datasheet does not name this terminal or state its polarity, as the terminal diagram is not reproduced in the text. |
