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.
