The BU406 is a silicon NPN switching transistor manufactured by STMicroelectronics, designed for high-speed switching applications such as horizontal deflection output stages in monochrome TV receivers.
Key electrical characteristics include a collector-emitter voltage (VCEO) of 200V, collector-base voltage (VCBO) of 400V, and continuous collector current (IC) of 7A. The device can handle peak repetitive currents of 10A and non-repetitive currents of 15A. Power dissipation is rated at 60W at case temperature 25°C. The transistor offers a transition frequency of 10MHz and a fast turn-off time of 0.75µs. Saturation voltages are 1V for VCE(sat) and 1.2V for VBE(sat) at 5A/0.5A.
The BU406 is housed in a TO-220-3 through-hole plastic package. Thermal characteristics include a junction-to-case thermal resistance of 2.08°C/W and junction-to-ambient of 70°C/W. Maximum junction temperature is 150°C, with a storage temperature range of -65 to 150°C.
Design considerations include a second breakdown current of 4A at 40V for safe operating area. The device is optimized for horizontal deflection circuits in large screen CRT monitors and TVs.
