Product Summary

The TIP122 is a complementary Silicon high-power transistor. And it can be used in general–purpose power amplifier and low–speed switching applications.

Parametrics

TIP122 absolute maximum ratings: (1)Collector–emitter voltage: 100 V; (2)Collector–base voltage: 100 V; (3)Emitter - base voltage: 5.0 Vdc; (4)Collector current - continuous: 5 Adc; (5)Collector current - peak: 8 Adc; (6)Base current: 120 0Adc; (7)Total power dissipation @ Tc=25°C: 65 W; (8)Total power dissipation derate above 25°C: 0.52 W/°C; (9)Operating and storage junction temperature range: -65 to +150°C.

Features

TIP122 features: (1)Collector - emitter saturation voltage @ 100 mAdc: VCEO(sus) = 100 Vdc (Min); (2)Collector - mitter Sustaining Voltage: VCEO(sus) = 100 Vdc (Min); (3)High Current Gain: hFE = 2500 (Typ) @ IC = 4.0 Adc; (4)Compact TO-220 AB Package; (5)Monolithic construction with built–in base–emitter shunt resistors.
