SWITCHMODE NPN Silicon Planar Power Transistor

The BUH51 has an application specific state–of–art die designed for use in 50 Watts Halogen electronic transformers.

This power transistor is specifically designed to sustain the large inrush current during either the start–up conditions or under a short circuit across the load.

This High voltage/High speed product exhibits the following main features:

• Improved Efficiency Due to the Low Base Drive Requirements:

— High and Flat DC Current Gain hFE

— Fast Switching

• Robustness Thanks to the Technology Developed to Manufacture
