RCLAMP0502BATCT-MS from MSKSEMI, 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 | Protected data line 1 (unidirectional TVS diode to common pin 3), reverse stand-off 5 V max working voltage, 0.7 pF typ. capacitance. |
| 2 | I/O2 | passive | Protected data line 2 (unidirectional TVS diode to common pin 3), reverse stand-off 5 V max working voltage, 0.7 pF typ. capacitance. |
| 3 | GND | power_in | Common anode of both TVS diodes, connected to ground as the return for ESD and surge current (3.5 A peak pulse, 8/20 μs). |
