Central Semiconductor Corp. Bipolar Transistors - BJT CMXT3946 TR

The CMXT3946 is a dual complementary silicon transistor in a SOT-26 surface mount package, designed for general purpose small signal and switching applications. It features matched NPN and PNP transistors with a continuous collector current rating of 200 mA, collector-emitter voltage of 40 V, and power dissipation of 350 mW. The operating and storage junction temperature range is -65 to +150 °C. Thermal resistance is 357 °C/W. Current gain (hFE) ranges from 30 to 300 depending on collector current, and transition frequency is 250 to 300 MHz. Saturation voltages are specified up to 0.95 V for base-emitter and 0.40 V for collector-emitter under rated conditions. Capacitances are 4.0 to 4.5 pF for collector-base and 8.0 to 10 pF for base-emitter. Switching times are 35 ns for rise and fall, 200 to 225 ns for storage, and 50 to 75 ns for fall. The device is marked with code X46.
