Tag: BD203 Pinout

Introduction The BD204 is a PNP silicon power transistor designed for medium-power amplification and switching applications, commonly used in audio amplifier output stages, regulator circuits, and complementary push-pull designs. Its high breakdown voltage and robust power handling make it suitable for circuits requiring the negative side of the waveform to be driven. According to the […]

Introduction The BD203 is an NPN silicon power transistor designed for medium-power amplification and switching applications. It’s commonly used in audio amplifier outputs, hi-fi circuits, and power driver stages. The device is built to handle relatively high currents and voltages for its class, making it suitable for kind of circuits where reliable power gain is […]
