Brightking · ESD And Surge Protection (TVS/ESD) · SOT-23
SDT23C05L02-AT from Brightking, 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/O1 | passive | First protected bidirectional I/O line (TVS diode to pin 3 GND); 5V reverse stand-off voltage, 5 µA max leakage at VR=5V, 150 pF max capacitance to GND. |
| 2 | I/O2 | passive | Second protected bidirectional I/O line (TVS diode to pin 3 GND); 5V reverse stand-off voltage, 5 µA max leakage at VR=5V, 150 pF max capacitance to GND. |
| 3 | GND | power_in | Common ground reference for both TVS diodes; the I/O pins are protected against ESD of ±30kV contact and ±30kV air discharge relative to it. |
