DDTC144VE-7-F

Diodes Incorporated · Digital Transistors · SOT-523

DDTC144VE-7-F from Diodes Incorporated, in a SOT-523. 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 Input pin (base of the built-in bias network via R1); the datasheet gives an input voltage range of -15 to +40 V for DDTC144VE, referenced to pin 2.
2 GND power_in Ground / common reference pin (0 V) to which the supply voltage (3)-(2) and input voltage (1)-(2) are specified.
3 OUT output Open-collector output; the supply voltage (3) to (2) is rated at 50 V maximum and the output current is rated at 30 mA maximum for DDTC144VE.
