# UCLAMP0501H-TP

**TECH PUBLIC** · ESD Protection Devices · SOD-523

UCLAMP0501H-TP from TECH PUBLIC, in a SOD-523. 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 | K | passive | Cathode, the marked-bar end of the 1-line uni-directional TVS diode, connects to the protected data or power line (5V max reverse working voltage, 6V min breakdown at 1mA). |
| 2 | A | passive | Anode of the uni-directional TVS diode, normally connected to ground, with clamping of 8V at 1A and 14V max at 22A (8x20µs). |
