PESD2CAN from DOWO, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	I/O1	passive	Protected data/transmission line 1. Bi-directional TVS clamp between pin 1 and pin 3 (common), 24V VRWM, 28.5V typical breakdown, clamps at ~35V typ. at 1A (8/20µs).
2	I/O2	passive	Protected data/transmission line 2. Bi-directional TVS clamp between pin 2 and pin 3 (common), 24V VRWM, 28.5V typical breakdown, clamps at ~35V typ. at 1A (8/20µs).
3	COM	passive	Common cathode/anode node of the bi-directional TVS array. Both diode pairs return to this pin; typically tied to GND on a CAN/data-line protection network.
