The Darlington Bipolar Power Transistor is designed for general-purpose amplifier and low-speed switching applications. TIP120, TIP121, TIP122 (NPN), TIP125, TIP126, TIP127 (PNP) are complementary devices.
High DC Current Gain - hFE = 2500 (typ) @ IC = 4.0 Adc
Collector-Emitter Sustaining Voltage @ 100 mA
VCEO(sus) = 60 Vdc (Min) TIP120, TIP125
VCEO(sus) = 80 Vdc (Min) TIP121, TIP126
VCEO(sus) = 100 Vdc (Min) TIP122, TIP127
Low Collector-Emitter Saturation Voltage
VCE(sat) = 2.0 Vdc (Max) @ IC= 3.0 Adc = 4.0 Vdc (Max) @ IC= 5.0 Adc
Monolithic Construction with Built-In Base-Emitter Shunt Resistors
Compact TO-220 AB Package
