UDT26A05L05

TECH PUBLIC · Electrostatic And Surge Protection (TVS/ESD) · SOT-23-6

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.
