TPAZC199-04S from TECH PUBLIC, in a SOT-23-6. 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 | IO1 | passive | I/O protected data line 1 (Note 1: I/O pins are 1, 3, 4 and 6); reverse working voltage 5V max to ground, 0.3pF typ between I/O pins. |
| 2 | GND | power_in | Ground reference pin connected to the TVS diode in the center of the schematic; I/O pins are rated to this pin with VRWM 5V max. |
| 3 | IO2 | passive | I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); reverse working voltage 5V max to ground, 0.8pF max to ground. |
| 4 | IO3 | passive | I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); clamping voltage 15V max at IPP=1A (8x20µs). |
| 5 | VCC | power_in | Center pin of the schematic connected to the TVS diode cathode, which the features list calls the power line protected; the datasheet does not name it explicitly. |
| 6 | IO4 | passive | I/O protected data line (Note 1: I/O pins are 1, 3, 4 and 6); clamping voltage 20V max at IPP=4A (8x20µs). |
