BUW11A Description

Short technical summary and product information.

The BUW11A is a Silicon NPN Power Transistor manufactured by Philips, suitable for applications requiring high voltage and high speed switching. It is housed in a TO-3PN package.

Key electrical specifications include a Collector-Emitter Voltage (VCEO) of 450V and a continuous Collector Current (IC) of 5A, with a peak capability of 10A. The device offers a maximum power dissipation of 100W at 25℃ case temperature and a maximum junction temperature of 150℃. The Collector-Emitter Saturation Voltage (VCEsat) is rated at a maximum of 1.5V.

This transistor is designed for use in power conversion applications such as converters, inverters, switching regulators, and motor control systems. Its thermal resistance from junction to mounting base is 1.25 K/W, facilitating efficient heat dissipation.

The BUW11A exhibits a DC current gain (hFE) ranging from 10 to 35 under specified conditions. Switching characteristics include a turn-on time of 1.0 μs, a storage time of 4.0 μs, and a fall time of 0.8 μs, making it suitable for various switching applications.
