**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-363

RCLAMP0504FATCT from TECH PUBLIC, in a SOT-363. 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 | IO | passive | Data line I/O with TVS protection (ESD ±30kV air / ±25kV contact per IEC61000-4-2), 0.3pF typical I/O to I/O. |
| 2 | GND | power_in | Ground reference for the TVS array; clamping voltage I/O-GND is 16V max at IPP=4.5A (8/20µs). |
| 3 | IO | passive | Data line I/O with TVS protection (ESD ±30kV air / ±25kV contact per IEC61000-4-2), 0.3pF typical I/O to I/O. |
| 4 | IO | passive | Data line I/O with TVS protection (ESD ±30kV air / ±25kV contact per IEC61000-4-2), 0.3pF typical I/O to I/O. |
| 5 | VCC | power_in | Power line protection pin with 5V max reverse working voltage; clamping voltage Vcc-GND is 17V max at IPP=15A (8/20µs). |
| 6 | IO | passive | Data line I/O with TVS protection (ESD ±30kV air / ±25kV contact per IEC61000-4-2), 0.3pF typical I/O to I/O. |
