SDT23C05L02

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

SDT23C05L02 from UMW, 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 Protected bidirectional I/O line 1, clamped to pin 3 (GND) with 5V working voltage (VRWM) and 9.8V max clamping at IPP=1A.
2 I/O2 passive Protected bidirectional I/O line 2, clamped to pin 3 (GND) with 5V working voltage (VRWM) and 9.8V max clamping at IPP=1A.
3 GND power_in Common ground/reference node for both bidirectional TVS channels; capacitance is specified between the I/O pins and GND.
