The S8050M-D HY3D with Transistors is an NPN transistor manufactured by Blue Rocket, working within a total power dissipation of 800mA and at a voltage of 25V. This single-transistor device features a SOT-23 surface-mount package, and is RoHS (Restriction of Hazardous Substances Directive) compliant. It is often used for low power applications, such as line drivers, line switches, and logic level converters, due to its low collector-emitter breakdown voltage (BVce) and high current gain (hfe).
