The KRC404-RTK/P is a digital transistor manufactured by Korean Electronics Corporation (KEC) with a maximum collector current of 100mA and a maximum collector-emitter voltage of 50V, housed in an SC-70-3 package in accordance with RoHS (Restriction of Hazardous Substances) requirements. It is an NPN type transistor, meaning that it features a collector, emitter, and base connection and operates as an amplifier or switch, controlling current on the collector side when the base terminal is activated. The KRC404-RTK/P is ideal for applications such as drivers and buffers for high-speed switching, power management in portable systems, interface circuits, amplifiers, and switches.
