Overview
The PDTC143XU,115 is an NPN Resistor-Equipped Transistor (RET) housed in a SOT323 surface-mount package. It integrates bias resistors with nominal values of R1 = 4.7 kΩ and R2 = 10 kΩ. The device supports a collector-emitter voltage (VCEO) of 50 V and a continuous output current (IO) of 100 mA. Key electrical characteristics include a DC current gain (hFE) of 50 at IC = 10 mA, a transition frequency (fT) of 230 MHz, and a total power dissipation (Ptot) of 200 mW at 25°C ambient temperature. The junction-to-ambient thermal resistance is 625 K/W.
