Diodes Incorporated FZT491ATC is an NPN bipolar junction transistor (BJT) designed for robust performance in demanding applications. This component features a 40V collector-emitter breakdown voltage and a maximum collector current of 1A, with a low collector cutoff current of 100nA. Its high DC current gain (hFE) of 300 at 500mA and 5V, coupled with a transition frequency of 150MHz, makes it suitable for high-speed switching and amplification circuits. The device offers a maximum power dissipation of 2W and a low saturation voltage of 500mV at 100mA collector current. Packaged in a SOT-223-3 (TO-261-4, TO-261AA) for surface mounting, the FZT491ATC operates across a wide temperature range of -55°C to 150°C. This transistor finds application in various industrial and consumer electronics, including power management and signal conditioning. Supplied on Tape & Reel (TR).
