SWITCHMODE™ NPN Silicon Planar Power Transistor

The BUH51 has an application specific state−of−art die designed for use in 50 W Halogen electronic transformers.
This power transistor is specifically designed to sustain the large inrush current during either the startup conditions or under a short circuit across the load.
