Central Semiconductor Corp. Bipolar Transistors - BJT CXTA44 TR

The CXTA44 is a surface mount NPN silicon transistor designed for high voltage applications, housed in an SOT-89 package. It has a collector-base voltage rating of 450 V, a collector-emitter voltage rating of 400 V, and a continuous collector current of 300 mA. The device dissipates up to 1.2 W with a thermal resistance of 125 °C/W and operates over a junction temperature range of -65 to +175 °C. Current gain (hFE) ranges from 20 to 200 depending on collector current, and the transition frequency is 20 MHz. Collector-emitter saturation voltage is 0.75 V at 50 mA collector current. The part complies with RoHS standards.
