| NPN BU508DF SILICON DIFFUSED POWER TRANSISTORS The BU508DF is NPN transistors in a fully isolated SOT199 envelope (with integrated efficiency diode for the BU508DF). They are a high voltage, high speed switching and they are intended for use in horizontal deflexion circuits of colour television receivers.
