The NEC is a high-voltage, high-speed NPN power transistor designed for use in high-definition television (HDTV) horizontal deflection circuits and other high-voltage switching applications. It utilizes a diffusion prescaler structure to achieve high breakdown voltage and fast switching speeds. This component is characterized by its high collector current capability and robust power dissipation rating, making it suitable for driving inductive loads such as deflection yokes and flyback transformers. Users are advised to trace the circuit, analyze
