Central Semiconductor Corp. Darlington Transistors CEN-U45

The CEN-U45 is an NPN silicon Darlington transistor intended for general-purpose amplifier and driver applications requiring high gain and power dissipation. It is packaged in a TO-202 case with a 2.0 A continuous collector current, 40 V collector-emitter voltage rating, and 2.0 W power dissipation at 25℃ ambient temperature, increasing to 10 W with a 25℃ case temperature. The device offers a minimum DC current gain of 25,000 at 200 mA collector current and features a collector-emitter saturation voltage of 1.0 V at 200 mA and 1.5 V at 1.0 A. Operating and storage junction temperatures range from -65℃ to +150℃. Thermal resistance is 62.5 °C/W from junction to ambient and 12.5 °C/W from junction to case.
