RLST23A712C from RUILON Shenzhen Ruilongyuan Elec, in a SOT-23. 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/O | bidirectional | Protected I/O line of the bidirectional surge/ESD clamp (+12 V to -7 V line class), rated 350 W peak pulse power per line at tp = 8/20 µs and ±30 kV contact/air ESD per IEC61000-4-2. |
| 2 | I/O | bidirectional | Protected I/O line of the bidirectional surge/ESD clamp (+12 V to -7 V line class), rated 350 W peak pulse power per line at tp = 8/20 µs and ±30 kV contact/air ESD per IEC61000-4-2. |
| 3 | GND | power_in | Common GND reference of the clamp; the datasheet specifies the clamping limits between Pin3 and Pin1/Pin2 in both directions (reverse stand-off 12 V and 7 V, peak clamp 20 V and 10 V at 5 A). |
