UAT36A03L05

YAGEO · ESD And Surge Protection (TVS/ESD) · SOT-363

UAT36A03L05 from YAGEO, in a SOT-363. 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 I/O1 passive Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection.
2 GND power_in Ground connection at the anode of the TVS diode, the return for the steering diodes.
3 I/O2 passive Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection.
4 I/O3 passive Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection.
5 VP power_in Protected power line connection at the TVS diode cathode, with 3.3 V reverse stand-off voltage (VRWM).
6 I/O4 passive Protected high-speed data line input with a low-capacitance steering diode pair (0.5 pF max between I/O and GND at 0 V, 1 MHz) and ±8 kV contact / ±15 kV air ESD protection.
