BUJ403A Description

Short technical summary and product information.

The BUJ403A is a silicon diffused power transistor manufactured by NXP Semiconductors. Designed for high-voltage and high-speed switching applications, this NPN transistor is planar-passivated and housed in a TO-220AB package.

Key electrical specifications include a maximum collector-emitter voltage (Vcesm) of 1200V and a continuous collector current (Ic) of 6A. The total power dissipation (Ptot) is rated at 100W at 25°C case temperature. It offers a typical collector-emitter saturation voltage (Vcesat) of 0.15V at 2A collector current and 0.4A base current.

Dynamic characteristics include a typical fall time (tf) of 170ns. The transistor is suitable for applications such as high-frequency electronic lighting ballasts, converters, inverters, switching regulators, and motor control systems. Its TO-220AB package facilitates easy mounting.

Thermal performance is supported by a junction-to-mounting base thermal resistance (Rth j-mb) of 1.25 K/W.
