TS0512PMX

Shenzhen JingYang · ESD And Surge Protection (TVS/ESD) · SOT-143

TS0512PMX from Shenzhen JingYang, 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 reference pin for the two protected data lines (bottom-left position in the SOT-143 top view), per the datasheet pin configuration.
2 IO1 bidirectional Protected data line 1 (bottom-right position in the SOT-143 top view); the device clamps transients on this I/O to GND, with 5.0 V nominal reverse working voltage and 3.5 pF typical capacitance at 0 V.
3 IO2 bidirectional Protected data line 2 (top-right position in the SOT-143 top view); the device clamps transients on this I/O to GND, with 5.0 V nominal reverse working voltage and 3.5 pF typical capacitance at 0 V.
4 VCC power_in Supply-side pin (top-left position in the SOT-143 top view) listed in the datasheet pin configuration; the datasheet gives no separate voltage limit or function for this pin.
