LY23EA05
Liown · ESD And Surge Protection (TVS/ESD) · SOT-23
LY23EA05 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 uni-directional I/O line 1 (diode cathode), clamped to pin 3 ground with VRWM 5V and 8V max clamping at IPP = 1A. |
| 2 | I/O2 | passive | Protected uni-directional I/O line 2 (diode cathode), clamped to pin 3 ground with VRWM 5V and 14V max clamping at IPP = 23A (8/20µs). |
| 3 | GND | power_in | Common ground connection (diode anodes) to which both I/O pins are clamped. |
