BUL44G
SWITCHMODEt NPN
Bipolar Power Transistor
For Switching Power Supply Applications
The BUL44G have an applications specific state−of−the−art die
designed for use in 220 V line operated Switchmode Power supplies
and electronic light ballasts.
Features
• Improved Efficiency Due to Low Base Drive Requirements:
High and Flat DC Current Gain h_FE
Fast Switching
No Coil Required in Base Circuit for Turn−Off (No Current Tail)
• Full Characterization at 125°C
• Tight Parametric Distributions are Consistent Lot−to−Lot
• These Devices are Pb−Free and are RoHS Compliant*

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
