The DTA144EET1 is a PNP pre-biased transistor (Bias Resistor Transistor) from On Semiconductor, designed to replace a discrete transistor and its external resistor bias network. It integrates a series base resistor of 47 kΩ and a base-emitter resistor, simplifying circuit design and reducing board space.
Key electrical specifications include a maximum collector-base voltage of 50 V, collector-emitter voltage of 50 V, and a continuous collector current of 100 mA. The DC current gain (hFE) is a minimum of 80 at 5 mA collector current and 10 V collector-emitter voltage. The saturation voltage is 250 mV maximum at 300 µA base current and 10 mA collector current.
The device is housed in the SC-75 (SOT-416) surface-mount package with gull-wing leads, suitable for low-power applications. It dissipates up to 200 mW on an FR-4 board at 25°C ambient temperature, with a junction-to-ambient thermal resistance of 600 °C/W. The operating junction and storage temperature range is -55°C to 150°C.
This transistor is AEC-Q101 qualified and PPAP capable, making it suitable for automotive applications. The package is designed for wave or reflow soldering, and Pb-free packages are available.
