LY23BA05UL from Liown, in a SOT-23. 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 line 1 connected to the cathode of the first TVS diode, with a 5V maximum reverse working voltage and ±25kV air / ±20kV contact IEC 61000-4-2 ESD protection. |
| 2 | I/O2 | passive | Protected line 2 connected to the cathode of the second TVS diode, with a 5V maximum reverse working voltage and ±25kV air / ±20kV contact IEC 61000-4-2 ESD protection. |
| 3 | GND | power_in | Common anode of both TVS diodes, connected to ground as the return path for ESD and surge current. |
