DTC143EET1G Description

Short technical summary and product information.

The DTC143EET1G is an NPN pre-biased digital transistor from onsemi, integrating two bias resistors (R1 and R2, both 4.7kΩ) in a single SC-75 (SOT-416) surface mount package. This Bias Resistor Transistor (BRT) simplifies circuit design by eliminating external resistors, reducing board space and component count.

 

Key electrical specifications include a maximum collector-emitter voltage of 50 V, continuous collector current of 100 mA, and power dissipation of 200 mW. It features a DC current gain (hFE) of minimum 15 at Ic=5mA, Vce=10V, and a low Vce saturation voltage of 250 mV at Ib=1mA, Ic=10mA. The device supports surface mount assembly and is supplied in tape and reel with a standard package quantity of 3000 pieces.

 

The DTC143EET1G is suitable for switching and driver applications where space is at a premium, such as in portable electronics, digital control circuits, and load interfaces. It is RoHS3 compliant, Pb-Free, and Halogen Free (BFR free), meeting current environmental requirements.
