Central Semiconductor Corp. Bipolar Transistors - BJT CMUT3904 BK

The CMUT3904 is an NPN silicon transistor in an SOT-523 surface mount package, designed for general purpose amplification and switching. It has a collector-emitter voltage rating of 40 V, a continuous collector current of 200 mA, and a power dissipation of 250 mW. The device has a thermal resistance of 500 °C/W and operates from -65 to +150 °C. Current gain (hFE) ranges from 30 to 300 depending on collector current, with saturation voltage VCE(sat) up to 0.25 V at 10 mA and a transition frequency of 300 MHz. The SOT-523 package has a 3-pin configuration with the base, emitter, and collector assigned as pins 1, 2, and 3 respectively.
