Central Semiconductor Corp. Single Bipolar Transistors CMPT3640 BK

The CMPT3640 is a PNP silicon transistor in a SOT-23 surface mount package, designed for saturated switching applications. It has a collector-base voltage rating of 12 V, collector-emitter voltage of 12 V, continuous collector current of 80 mA, and power dissipation of 350 mW. The operating and storage junction temperature range is -65 to +150 °C, with a thermal resistance of 357 °C/W. Current gain (hFE) ranges from 20 to 120 depending on operating conditions. The collector-emitter saturation voltage is 0.20 V at 10 mA collector current and 1 mA base current, rising to 0.60 V at 50 mA and 5 mA. The transition frequency is 500 MHz at 10 mA collector current. The package pinout is Base-1, Emitter-2, Collector-3, with marking code C2J.
