RLST143A053LV

RUILON(Shenzhen Ruilongyuan Elec) · ESD Protection Devices · SOT-143

RLST143A053LV from RUILON(Shenzhen Ruilongyuan Elec), 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 Connects to the anode of the avalanche TVS diode and the lower steering-diode rail, serving as the ground/reference pin of the array (VRWM 5 V, VBR min 6 V at 1 mA).
2 I/O passive Protected line pin of the steering-diode array, rated for ±8 kV contact and ±15 kV air ESD per IEC61000-4-2 with 3 pF typical capacitance.
3 I/O passive Protected line pin of the steering-diode array, rated for ±8 kV contact and ±15 kV air ESD per IEC61000-4-2 with 3 pF typical capacitance.
4 VCC/TVS cathode power_in Connects to the upper steering-diode rail and the cathode of the avalanche TVS diode, which clamps at 9.8 V (VC at 1 A) with 5 V working voltage.
