Central Semiconductor Corp. Bipolar Transistors - BJT CMKT2222A TR

The CMKT2222A is a dual NPN silicon transistor in an SOT-363 surface-mount package, designed for general-purpose switching and small-signal applications. Each transistor has a collector-emitter voltage rating of 40 V, a continuous collector current of 600 mA, and a power dissipation of 350 mW. The complementary pairs share switching characteristics including a saturation voltage of 0.3 V at 150 mA collector current and 1.0 V at 500 mA, with current gain (hFE) ranging from 40 to 300 depending on operating conditions. Transition frequency is 300 MHz, and thermal resistance is 357 °C/W. The device operates from -65 °C to +150 °C and meets RoHS standards. The SOT-363 package has six pins with defined emitter, base, and collector assignments per transistor. The 'TR' suffix denotes tape and reel packaging.
