Central Semiconductor Corp. Bipolar Transistors - BJT CMUT4401 TR

The CMUT4401 is an NPN silicon transistor in a SOT-523 surface mount package, designed for general purpose amplifier and switching applications. It has a collector-base voltage rating of 60 V, a collector-emitter voltage of 40 V, and a continuous collector current of 600 mA. Power dissipation is limited to 250 mW, with a thermal resistance of 500 °C/W. The operating and storage junction temperature range is -65 to +150 °C. Electrical characteristics include a VCE(sat) of up to 0.75 V at 500 mA collector current, hFE ranging from 100 to 300 at VCE=1.0 V and IC=150 mA, and a transition frequency of 250 MHz. The package has a three-lead layout with base, emitter, and collector defined on the bottom view.
