Kerafol BU2708AX BU Transistor NPN SOT 399 (TOP 3D) 8A 825V BU2708AX Data Sheet

High voltage, high speed switching npn transistor in a plastic full-pack envelope. Intended for use in horizontal
deflection circuits of colour television receivers. Features exceptional tolerance to base drive and collector current
load variations, resulting in a low worst-case dissipation. Designed to withstand V
