TIP120 Datasheet - New Jersey Semiconductor

... designed for general−purpose amplifier and low−speed switching applications.

FEATURES:
• Collector−Emitter Sustaining Voltage −
   VCEO(sus) = 60 V (Min) − TIP120, TIP125
                      = 80 V (Min) − TIP121, TIP126
                      = 100 V (Min) − TIP122, TIP127
• Low Collector−Emitter Saturation Voltage −
   VCE(sat) = 2.0 V (Max.) @ IC = 3.0 A 
• Monolithic Construction with Built−In Base−Emitter Shunt Resistors
