MMBTA44 is a high-voltage NPN bipolar transistor in an SOT-23-3 (TO-236) package, designed for switching and amplification in commercial and industrial applications. It has a collector-emitter voltage rating of 400 V, a maximum collector current of 300 mA, and a power dissipation of 350 mW when mounted on a PCB with 3 mm² copper pad per terminal. The junction temperature range is -55°C to +150°C. The device meets AEC-Q101 qualification for automotive applications when designated as MMBTA44A-Q or MMBTA44A-AQ. It complies with RoHS, REACH, and UL 94 V-0 standards. The typical DC current gain (hFE) ranges from 50 to 200 at 10 mA collector current, and the transit frequency exceeds 50 MHz. The collector-base capacitance is typ. 5 pF at 20 V. The case material is UL 94 V-0 compliant, and the part is taped and reeled in 3000-unit quantities.
