BU406 Description

Short technical summary and product information.

The BU406 is a silicon Epitaxial Planar NPN transistor housed in a standard Jedec TO-220 plastic package. This fast switching device is specifically designed for use in the horizontal deflection output stages of large screen MTV receivers with 110o CRT displays.

 

Key electrical specifications include a maximum collector-emitter voltage (VCE) of 200V and a maximum continuous collector current (IC) of 7A. It also features a maximum collector dissipation (Pc) of 60 Watts and a maximum transition frequency (fT) of 10 MHz. The transistor operates within a temperature range of -65°C to +150°C.

 

Beyond its primary application in TV and CRT horizontal deflection circuits, the BU406's fast switching speed, high voltage capability, and low saturation characteristics make it suitable for a variety of other electronic applications, including high-speed switching and high voltage applications. Its TO-220 package is designed for through-hole mounting.

 

To ensure safe operation, it is recommended not to use the BU406 at its full power rating, always staying at least 20 percent below the absolute maximum ratings. Specific guidance includes not exceeding 560mA for continuous collector current and 160V for collector-to-emitter voltage. Proper heatsinking is essential, and the heatsink tab must be isolated from circuit connections.
