Complementary Silicon Power Transistors

ON Semiconductor 

D44H Series (NPN),

D45H Series (PNP)

Complementary Silicon

Power Transistors

These series of plastic, silicon NPN and PNP power transistors can

be used as general purpose power amplification and switching such as

output or driver stages in applications such as switching regulators,

converters and power amplifiers.

Features

• Low Collector−Emitter Saturation Voltage

• Fast Switching Speeds

• Complementary Pairs Simplifies Designs

• These Devices are Pb−Free and are RoHS Compliant*
