**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · MSOP-10

RCLAMP0514M from TECH PUBLIC, in a MSOP-10. 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 | Line 1 | passive | Protected data line 1 (flow-through, pin 1 to pin 10 side pairing not stated); steered by diodes to Vcc and GND, 5V working voltage, 0.3pF typ between I/O pins. |
| 2 | NC | unconnected | No connect. |
| 3 | Vcc | power_in | Power line connection of the diode array, protected line with reverse working voltage 5V max. |
| 4 | Line 3 | passive | Protected data line 3 steered by diodes to Vcc and GND, with 5V working voltage and 6V min breakdown at 1mA. |
| 5 | NC | unconnected | No connect. |
| 6 | Line 4 | passive | Protected data line 4 steered by diodes to Vcc and GND, with ESD protection of ±25kV air and ±20kV contact per IEC 61000-4-2. |
| 7 | NC | unconnected | No connect. |
| 8 | GND | power_in | Ground reference for the array; all I/O pin ratings are specified to ground. |
| 9 | Line 2 | passive | Protected data line 2 steered by diodes to Vcc and GND, with 14V max clamping at 1A and 20V max at 5A (8/20µs). |
| 10 | NC | unconnected | No connect. |
