The S8550M-D PNP transistor manufactured by Blue Rocket is a surface-mount package transistor in a SOT-23 RoHS package with a maximum PNP collector current of 800mA and a maximum collector-emitter voltage of 25V. It is designed for general-purpose amplification and switching applications, as well as driving high current surface-mount LEDs. The S8550M-D features a well-matched hFE, fast switching time, and low saturation voltage, which make it an ideal choice for portable and space-constrained design. It also features an electrostatic discharge protection circuit and is RoHS compliant.
