RCLAMP0502BATCT from TECH PUBLIC, in a SOT-523. 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	TVS I/O line 1 protected by a steering diode to pin 3, with 5V max reverse working voltage and 0.6pF max capacitance to ground.
2	I/O2	passive	TVS I/O line 2 protected by a steering diode to pin 3, with 5V max reverse working voltage and 0.6pF max capacitance to ground.
3	GND	power_in	Common ground connection of the 2-line TVS array, shared by both diodes.

Symbol: RCLAMP0502BATCT
Footprint: Package_TO_SOT_SMD:SOT-523
3D model: SOT-523, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
3D model files: rclamp0502batct-etched.step / rclamp0502batct-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rclamp0502batct.step / rclamp0502batct.glb are the bare package body.
