The MMBTRC113SS with Bipolar Transistors - Pre-Biased Digital Transistor, SOT-23, 50V, 100mA is a four-pin SOT-23 minuscule surface mount digital transistor manufactured by Diotec. It has two switching transistors and a pre-biased base connection in a small outline package. The device features excellent switching performance through a wide range of collector-base voltage and collector current. It has a small on-resistance that provides low power waste. The MMBTRC113SS can operate at up to 50V of collector-base voltage and 100mA of collector current. It can be used in applications such as motor control, power switching, audio amplifier, and LED control.
