NXP USA Inc. TOPFET™ BUK205-50Y-118 is a high-side N-Channel power switch designed for general-purpose applications. This component, packaged in a D2PAK (TO-263-5) for surface mounting, delivers up to 6A continuous output current with a low on-resistance of typically 45mOhm. It features robust fault protection including fixed current limiting, over-temperature protection, over-voltage protection, and undervoltage lockout (UVLO). The BUK205-50Y-118 includes a status flag for output monitoring and operates across a load voltage range of 5V to 40V. Its intended applications span industrial automation, automotive systems, and consumer electronics requiring reliable power management.
