PDTA144EU,115

PDTA144EU,115 Description

The PDTA144EU,115 from Nexperia is a surface-mount, pre-biased PNP bipolar transistor designed for low-power switching and amplification applications. Encased in a compact SOT323 package, it integrates 47 kΩ base (R1) and emitter-base (R2) resistors, simplifying circuit design by eliminating external biasing components. With a collector-emitter voltage (Vce) rating of 50V and a maximum collector current (Ic) of 100 mA, it delivers reliable performance in space-constrained designs. The device boasts a low Vce saturation voltage of 150 mV (at 500 µA Ib, 10 mA Ic), ensuring efficient switching with minimal power loss. Its DC current gain (hFE) of 80 (at 5 mA, 5V) provides stable amplification, while the 1 µA collector cutoff current enhances energy efficiency.
