BUL45D2G  
High Speed, High Gain  
Bipolar NPN Power  
Transistor  
with Integrated Collector−Emitter Diode  
and Built−in Efficient Antisaturation  
Network  
POWER TRANSISTOR  
5.0 AMPERES,  
700 VOLTS, 75 WATTS  
The BUL45D2G is state−of−art High Speed High gain BiPolar  
transistor (H2BIP). High dynamic characteristics and lot−to−lot  
minimum spread (
 
150 ns on storage time) make it ideally suitable for  
light ballast applications. Therefore, there is no need to guarantee an h  
window. It’s characteristics make it also suitable for PFC application.
