TECH PUBLIC · ESD And Surge Protection (TVS/ESD) · SOT-143
UET14A05L03-BK-TP from TECH PUBLIC, in a SOT-143. 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 | GND | power_in | Ground reference at the common anode of the steering diodes and the TVS zener (junction capacitance specified IO to GND, 0.8 pF typ, 0.9 pF max). |
| 2 | IO1 | bidirectional | Protected data/IO line between the steering diode pair, clamped to 10 V max at 1 A and 15 V max at 6 A (8x20 µs), with 0.3 pF typ IO-to-IO capacitance. |
| 3 | IO2 | bidirectional | Protected data/IO line between the second steering diode pair, with 5 V reverse working voltage max, ±30 kV air/contact ESD per IEC 61000-4-2 and 6 A peak pulse current (8/20 µs). |
| 4 | VCC | power_in | Positive rail at the common cathode of the steering diodes and the TVS zener, with 5 V max reverse working voltage and 6.5 V min breakdown at 1 mA. |
