DTA143ZET1G Description

Short technical summary and product information.

The DTA143ZET1G from onsemi is a PNP digital transistor (Bias Resistor Transistor) that integrates a bias resistor network consisting of R1=4.7kΩ and R2=47kΩ. This monolithic design simplifies circuit layout by eliminating external bias components. The device is rated for a collector-base breakdown voltage of 50V and a continuous collector current of 100mA.

 

Key electrical characteristics include a minimum DC current gain (hFE) of 80 at Ic=5mA, Vce=10V, and a collector-emitter saturation voltage of 250mV at Ib=300µA, Ic=10mA. The input forward voltage is rated up to 30V, with a reverse voltage limit of 5V.

 

The transistor is housed in a compact SC-75 (SOT-416) surface-mount package, suitable for automated assembly. It is qualified as RoHS3 compliant, Pb-Free, and Halogen Free/BFR Free.
