                      Product Overview

                      The BU508AW is a 700V High Voltage NPN Power Transistor for standard definition CRT display. It is manufactured using diffused collector in planar technology adopting new and enhanced high voltage structure for updated performance to the horizontal deflection stage. Fast switching times and very low saturation voltage resulting in reduced switching and conduction losses.

                      • State-of-the-art technology - Diffused collector enhanced generation
                      • Stable performances versus operating temperature variation
                      • Low base-drive requirement
                      • Tight hFE range at operating collector current
                      • High ruggedness
                      • Well-controlled hFE parameter for increased reliability
