ESD12VL2BT-MS from MSKSEMI, 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 bidirectional line 1 (ESD12VL2BT-MS: VRWM 12V max, VB 13.3V min, CT 20pF max) to be clamped against the common pin. |
| 2 | I/O2 | passive | Protected bidirectional line 2 (ESD12VL2BT-MS: VRWM 12V max, VB 13.3V min, CT 20pF max) to be clamped against the common pin. |
| 3 | COMMON | passive | Common reference pin shared by both protection channels, shown as the single top lead in the pin configuration drawing. |
