ESDCAN04-2BLY 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 | IO1 | bidirectional | CAN line 1 (e.g. CAN_H) protection I/O; bidirectional TVS to GND with 25.5 V stand-off (VRM), 27.5 V min breakdown (VBR), 43 V max clamping at 3 A (8/20 µs), 17 pF typ junction capacitance. |
| 2 | GND | power_in | Common ground reference for both TVS diode stacks; max leakage 0.05 µA at VRM = 25.5 V (Tamb = 25 °C). |
| 3 | IO2 | bidirectional | CAN line 2 (e.g. CAN_L) protection I/O; bidirectional TVS to GND with the same 25.5 V stand-off / 27.5 V breakdown ratings as IO1; capacitance variation ΔC between IO1 and IO2 vs. GND is 19 pF max. |
