SDT23C24L02-AT

Brightking · ESD And Surge Protection (TVS/ESD) · SOT-23

SDT23C24L02-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 Bidirectional ESD-protected I/O line 1, clamped to pin 3 (GND) with VRWM 24V, leakage max 1 µA at VR=24V and CJ max 40 pF to GND.
2 I/O2 passive Bidirectional ESD-protected I/O line 2, clamped to pin 3 (GND) with VRWM 24V, leakage max 1 µA at VR=24V and CJ max 40 pF to GND.
3 GND power_in Common ground reference shared by both TVS diode paths; protects against ±15kV contact and ±25kV air ESD.
