# RLST236A052LV

**RUILON Shenzhen Ruilongyuan Elec** · ESD And Surge Protection (TVS/ESD) · SOT-23-6L

RLST236A052LV from RUILON Shenzhen Ruilongyuan Elec, in a SOT-23-6L. 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 | I/O1 | passive | Protected line 1 (internally tied to pin 6), steered by diodes to the TVS for 5V VRWM, 90 W 8/20μs peak pulse power per line and ±15kV air / ±8kV contact ESD. |
| 2 | GND | power_in | Common ground, connected to the anode of the internal TVS diode and the lower steering diodes in the electrical symbol. |
| 3 | I/O2 | passive | Protected line 2 (internally tied to pin 4), steered by diodes to the TVS for 5V VRWM, 1.2 pF typical capacitance and ±8kV contact ESD. |
| 4 | I/O2 | passive | Protected line 2 (internally tied to pin 3), clamping at 13 V at 1 A (8/20μs). |
| 5 | VP | passive | Upper rail node connected to the cathode of the internal TVS diode and the upper steering diodes, with 6 V minimum breakdown at 1 mA; no label is given in the datasheet. |
| 6 | I/O1 | passive | Protected line 1 (internally tied to pin 1), with 1 µA maximum reverse leakage at VRWM = 5 V. |
