Central Semiconductor Corp. Bipolar Transistors - BJT CMUT3904 TR

The CMUT3904 is an NPN silicon transistor in an SOT-523 surface mount package, designed for small-signal amplifier and switching applications. 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 operates within a junction temperature range of -65°C to +150°C and has a thermal resistance of 500 °C/W. Current gain (hFE) ranges from 30 to 300 depending on collector current. Transition frequency (fT) is 300 MHz at 10 mA collector current. The SOT-523 package has a three-lead configuration with pinout: base, emitter, collector. The part meets RoHS compliance and is marked AC1. The 'TR' suffix indicates tape and reel packaging.
