Diotec Semiconductor Single Bipolar Transistors MPSA44BK

The MPSA44BK is an NPN bipolar transistor in a TO-92 package, rated for a collector-emitter voltage of 400 V and a continuous collector current of 300 mA. It dissipates up to 625 mW with leads held at ambient temperature 2 mm from the case, and operates with a junction temperature range of -55°C to +150°C. The device has a minimum DC current gain of 50 at 10 mA collector current and a gain-bandwidth product exceeding 50 MHz. It complies with RoHS, REACH, and Conflict Minerals requirements, and the 'BK' suffix indicates bulk packaging with a 1.27 mm pitch. Thermal resistance from junction to ambient is less than 200 K/W. The case material meets UL 94V-0 standards, and soldering is rated for 260°C for 10 seconds.
