TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-323
D1213A-02WL from TECH PUBLIC, in a SOT-323. 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 | CH1 | passive | ESD-protected line 1 (uni-directional); 3.3V max reverse working voltage, 0.35pF typical to CH2 and 0.7pF max to GND. |
| 2 | CH2 | passive | ESD-protected line 2 (uni-directional); 3.3V max reverse working voltage, 0.35pF typical to CH1 and 0.7pF max to GND. |
| 3 | GND | power_in | Common ground return for both ESD protection channels, shown as the single lead on the opposite side of the package. |
