onsemi Digital Transistor BU406G, 400V NPN, Through Hole, TO-220, 3-Pin, 60W

The onsemi BU406G is a high-voltage NPN power transistor designed for demanding industrial, electronic, and commercial applications, requiring robust performance and reliability. With a collector-emitter voltage rating of 400V and maximum power dissipation of 60W, this device is engineered for precision switching and amplification tasks.

This bipolar transistor uses a TO-220 through-hole package with a three-pin format, enabling compatibility with a wide range of circuit board designs. Its NPN configuration delivers fast electronic switching - making it especially suited for horizontal deflection output stages in television and CRT applications. It features a low saturation voltage (maximum VCE(sat) of 1V at 5A) to optimize efficiency and reduce thermal losses.

With a maximum collector-base voltage of 400V, emitter-base voltage up to 6V, and minimum DC current gain (hFE) of 10, the BU406G ensures stable and reliable amplification. It is capable of operating at temperatures up to 150°C, providing durability in challenging thermal environments. The device offers a fast switching speed (tf = 750 ns maximum), facilitating high-frequency operation for industrial and electronic power control.

Measuring 10.53mm in length, 9.28mm in height, and 4.83mm in width, this transistor is compact for dense PCB layouts, while still providing robust handling and thermal characteristics due to its TO-220 form factor. The three-pin configuration supports straightforward integration into both new designs and retrofits.

Typical use cases include industrial control systems, power supplies, switching amplifiers, television and CRT circuits, and any high-voltage or high-current designs requiring reliable NPN transistor performance. The BU406G is suitable for both laboratory and manufacturing environments, with RoHS-compliant construction and a Pb-free package available.
