ElecSuper · ESD And Surge Protection (TVS/ESD) · SOT-143
PRTR5V0U2X-ES from ElecSuper, 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 | Connect to GND; this is the ground reference for the two-line ESD clamp. |
| 2 | IO | bidirectional | I/O line for the protected high-speed data line; the datasheet gives 0.6 to 0.8 pF I/O-to-I/O junction capacitance (VR=0V, f=1MHz) and a reverse stand-off voltage of 5.0 V. |
| 3 | IO | bidirectional | I/O line for the second protected high-speed data line; the datasheet gives 1.2 to 1.6 pF I/O-to-GND junction capacitance (VR=0V, f=1MHz) and a reverse stand-off voltage of 5.0 V. |
| 4 | Vcc | power_in | Connect to Vcc; the datasheet gives a reverse stand-off voltage of 5.0 V (VRWM) for the protected rail. |
