LY23BA05UL

Liown · ESD Protection Devices · SOT-23

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.
