DDTC123ECAQ-7-F

Diodes Incorporated · Digital Transistors · SOT-23-3

DDTC123ECAQ-7-F from Diodes Incorporated, in a SOT-23-3. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Base input through built-in series resistor R1 (2.2 kΩ nom). Input voltage range -10 V to +12 V. Drives the NPN base via R1 with R2 (2.2 kΩ) shunting base-to-emitter for defined off-state.
2 GND passive Emitter / common ground reference (labeled GND(0) on the device schematic). Return for both the input bias network (R2) and the output collector current.
3 OUT output Open-collector output. Absolute max VCC (pin 3 to pin 2) = 50 V; max output/collector current IC = 100 mA. Pulls low toward VO(on) ≈ 0.1 V (max 0.3 V) when input is asserted.
