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

TPESD0514M-1 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 | ESD-protected I/O data line 1 (steering diodes to Vcc and GND), 0.3pF typ line-to-line capacitance, 5V max reverse working voltage. |
| 2 | NC | unconnected | No connection. |
| 3 | Vcc | power_in | Power line / positive rail connection of the TVS array, protected by the internal diode structure; 5V reverse working voltage. |
| 4 | Line 3 | passive | ESD-protected I/O data line 3 (steering diodes to Vcc and GND), 0.3pF typ line-to-line capacitance, 5V max reverse working voltage. |
| 5 | NC | unconnected | No connection. |
| 6 | Line 4 | passive | ESD-protected I/O data line 4 (steering diodes to Vcc and GND), 0.3pF typ line-to-line capacitance, 5V max reverse working voltage. |
| 7 | NC | unconnected | No connection. |
| 8 | GND | power_in | Ground reference for the TVS diode array. |
| 9 | Line 2 | passive | ESD-protected I/O data line 2 (steering diodes to Vcc and GND), 0.3pF typ line-to-line capacitance, 5V max reverse working voltage. |
| 10 | NC | unconnected | No connection. |
