DTA143EET1G Description

Short technical summary and product information.

The DTA143EET1G is a PNP pre-biased digital transistor (Bias Resistor Transistor - BRT) from On Semiconductor. It integrates a series base resistor (R1=4.7kΩ) and a base-emitter resistor (R2=4.7kΩ) in a single SC-75 surface mount package, eliminating the need for external bias components. This simplifies circuit design and reduces board space.

 

Key electrical specifications include a maximum collector-emitter breakdown voltage of 50V, continuous collector current of 100mA, and power dissipation of 200mW. The device offers a minimum DC current gain (hFE) of 15 at Ic=5mA, Vce=10V, and a maximum Vce saturation of 250mV at Ib=1mA, Ic=10mA. The input forward voltage is rated at 30V maximum, and input reverse voltage at 10V maximum.

 

This BRT is suitable for switching and amplification applications where space and component count are critical. The SC-75 package (SOT-416) is designed for surface mount assembly and is supplied in tape and reel packaging with a standard quantity of 3000 pieces. The device is RoHS3 compliant, Pb-Free, and Halogen Free/BFR Free.
