UDT26A05L05 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 | Protected I/O line (note 1: I/O pins are 1, 3, 4 and 6) with reverse working voltage of 5 V max to ground and 0.8 pF max capacitance to ground. |
| 2 | GND | power_in | Ground reference of the TVS array, shown in the pin schematic as the common return of the I/O steering diodes and the central TVS diode. |
| 3 | IO2 | passive | Protected I/O line (note 1: I/O pins are 1, 3, 4 and 6) with 5 V max reverse working voltage and clamping voltage of 15 V max at IPP = 1A. |
| 4 | IO3 | passive | Protected I/O line (note 1: I/O pins are 1, 3, 4 and 6) with 0.4 pF max capacitance between I/O pins and 20 V max clamping at IPP = 3A. |
| 5 | VCC | power_in | Power line protected by the central TVS diode, per the features stating up to 4 data lines and one power line are protected; the schematic shows it as the upper rail. |
| 6 | IO4 | passive | Protected I/O line (note 1: I/O pins are 1, 3, 4 and 6) with 0.5 µA max reverse leakage at VRWM = 5 V and ESD protection of ±30 kV air / ±25 kV contact. |
