The BUF405A from ST is an NPN power transistor designed for high-voltage, fast-switching applications. It is suitable for use in switch mode power supplies and motor drivers, offering easy drive circuits and high reliability.
Key electrical characteristics include a Collector-Emitter Voltage (VCEV) of 1000V and a Collector-Emitter Voltage (VCEO) of 450V. The continuous Collector Current (IC) is rated at 7.5A, with a peak current (ICM) of 15A. The transistor operates at switching speeds up to 100 KHz.
Available in TO-220 and TO-220FP packages, the BUF405A is designed for industrial and professional power driving applications. Its superior switching performance and low crossover losses contribute to reduced dissipation and lower operating temperatures in equipment.
Absolute maximum ratings include a maximum junction temperature of 150°C and storage temperatures from -65°C to 150°C. Thermal resistance (junction-to-case) is 1.56 °C/W for the TO-220 package.
