The TIP120 from STMicroelectronics is a through hole complementary power darlington transistor in TO-220 package. This device manufactured in planar technology with "base island" layout and monolithic darlington configuration resulting in exceptional high gain performance coupled with very low saturation voltage.
Collector to emitter voltage (Vce) is 60V
Collector current (Ic) is 5A
Power dissipation (Pd) is 65W
Collector to emitter saturation voltage of 4V at 5A collector current
