DTD143EC is an NPN digital transistor with built-in bias resistors (R1 = R2 = 4.7 kΩ) in an SOT-23 package, designed for inverter, interface, and driver applications. It has a maximum collector current of 500 mA and a collector-emitter voltage of 50 V. The device operates with an input voltage range of -10 to 30 V and dissipates up to 200 mW. The junction temperature ranges from -55 °C to 150 °C. The transistor features thin-film bias resistors enabling negative input biasing and simplified circuit design. It meets the AEC-Q200 qualification standard.
DTD143EC is an digital transistor (Resistor built-in type transistor). The bias resistors consist of thin-film resistors with complete isolation to allow negative.
