DTA144WET1G Description

Short technical summary and product information.

The DTA144WET1G is a PNP pre-biased digital transistor (Bias Resistor Transistor, BRT) from ON Semiconductor that integrates a monolithic bias resistor network, eliminating external components and reducing board space. It features a built-in series base resistor (R1) of 47kΩ and a base-emitter resistor (R2) of 22kΩ.

Electrical specifications include a maximum collector-base voltage (VCBO) of 50V, maximum collector-emitter voltage (VCEO) of 50V, and continuous collector current (IC) of 100mA. The DC current gain (hFE) is minimum 80 at Ic=5mA, Vce=10V, and maximum Vce saturation is 250mV at Ib=300µA, Ic=10mA. Power dissipation is limited to 200mW.

The device is housed in a compact SC-75 (SOT-416) surface mount package, suitable for low-power switching and amplifier applications. It is Pb-free, Halogen Free/BFR Free, and RoHS compliant as verified by the manufacturer datasheet.
