HIGH VOLTAGE FAST-SWITCHING
NPN POWER TRANSISTORS
s HIGH SWITCHING SPEED NPN POWER
TRANSISTORS
s EASY TO DRIVE
s HIGH VOLTAGE FOR OFF-LINE
APPLICATIONS
s 100 KHz SWITCHING SPEED
s LOW COST DRIVE CIRCUITS
s LOW DYNAMIC SATURATION
APPLICATIONS:
s SWITCH MODE POWER SUPPLIES
s MOTOR DRIVERS
DESCRIPTION
These Easy-to-Drive FASTSWITCH NPN power
transistors are specially designed for high
reliability industrial and professional power driving
applications such us motor drives and off-line
switching power supplies. ETD transistors will
operate using easy drive circuits at up to 100KHz;
this helps to simplify designs and improve
reliability. The superior switching performance
and low crossover losses reduce dissipation and
consequently lowers the equipment operating
temperature.
