# RLST236A054LV

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

RLST236A054LV 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 | ESD/TVS-protected line 1 (steering diode pair to the central TVS), 5V working voltage, 1.5pF typical capacitance. |
| 2 | GND | power_in | Common ground connected to the anode of the central TVS diode in the electrical symbol; the datasheet gives no text label for this pin. |
| 3 | I/O2 | passive | ESD/TVS-protected line 2 (steering diode pair to the central TVS), 5V working voltage, 1.5pF typical capacitance. |
| 4 | I/O3 | passive | ESD/TVS-protected line 3 (steering diode pair to the central TVS), 5V working voltage, 1.5pF typical capacitance. |
| 5 | VCC/TVS cathode | power_in | Common rail connected to the cathode of the central TVS diode (VRWM 5V, VBR 6V min at 1mA); the datasheet gives no text label for this pin. |
| 6 | I/O4 | passive | ESD/TVS-protected line 4 (steering diode pair to the central TVS), 5V working voltage, 1.5pF typical capacitance. |
