The DTB113ECHZGT116 is a pre-biased PNP bipolar junction transistor (BJT) manufactured by Rohm Semiconductor. This transistor is designed for a maximum voltage of 50 V and can handle a current of up to 500 mA, making it suitable for low to moderate power applications. It operates with a frequency of 200 MHz and has a power dissipation capacity of 200 mW, all in a compact surface mount package type SST3. It features an integrated biasing network with a base current capability of 500 nA and resistors of 1 kOhm each, which helps simplify circuit design by reducing the number of external components needed.
