MSKSEMI · ESD And Surge Protection (TVS/ESD) · SOT-143
PRTR5V0U2X-MS from MSKSEMI, in a SOT-143. 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 | GND | power_in | Ground pin, connected to the anode of the internal avalanche TVS diode and the lower steering-diode rail. |
| 2 | IO1 | passive | Protected data line I/O 1 (steering-diode midpoint), with 0.45pF typical I/O-to-I/O and 0.95pF I/O-to-GND capacitance. |
| 3 | IO2 | passive | Protected data line I/O 2 (steering-diode midpoint), with 0.45pF typical I/O-to-I/O and 0.95pF I/O-to-GND capacitance. |
| 4 | VCC | power_in | Upper steering-diode rail tied to the TVS cathode, with 1.0pF VCC-to-GND capacitance and 5.5V reverse stand-off voltage. |
