DRDC3105F-7

Diodes Incorporated · Gate Drive ICs · SOT-23

DRDC3105F-7 from Diodes Incorporated, 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 IN input Logic-level drive input to the internal BJT; the output is guaranteed on above 1.5V and off below 400mV, with 6.0V maximum forward input voltage and -0.5V reverse.
2 GND power_in Ground reference for the driver, which returns the output sink current up to 500mA continuous.
3 OUT output Open-collector output that sinks up to 500mA continuous from the relay coil, with an internal zener clamping at 6.6V (6.2V to 7.0V at 10mA).
