ESDA14V2L from STMicroelectronics, 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 I/O line 1; internal unidirectional TVS diode cathode, clamps positive transients and diverts negative transients to pin 3 (common); VBR 14.2-15.8V typ. for ESDA14V2L. |
| 2 | I/O2 | passive | Protected I/O line 2; internal unidirectional TVS diode cathode, clamps positive transients and diverts negative transients to pin 3 (common); VBR 14.2-15.8V typ. for ESDA14V2L. Connecting pin 1 and pin 2 together allows the device to be used as a bidirectional suppressor. |
| 3 | COM | power_in | Common node shared by the anodes of both internal TVS diodes (functions as the ground/return reference for the ESD clamp paths from pins 1 and 2). |
