The 2SCR574D3TL1 is a NPN (negative polarity, negative) bipolar transistor (BJT) manufactured by ROHM. It has a maximum current rating of 2 amps, a maximum power rating of 10 watts, a low voltage collector-emitter rating of 80 volts, and an upper operating temperature of +150 degrees C. This device is most commonly used for low-noise and high-speed amplification, switching, and controlling applications. This makes it suitable for a range of circuits including audio amplifiers, high-frequency pulses, and power drivers. It features excellent gain and frequency characteristics, including a high frequency gain (fT = 4 MHz). It also features a low noise figure (NF = 1.8 dB) and low power consumption (IC = 200 mA).
