This is a datasheet of TIP120, 121, 122 NPN plastic power transistors and TIP125, 126, 127 PNP plastic power transistors, including absolute maximum ratings, ratings (at TA=25°C unless otherwise specified), pin configuration and dimensions.
The document provides data for a family of NPN and PNP power transistors offered in a TO‑220 plastic package. These devices are intended for linear and switching applications and are identified by part numbers TIP120, TIP121, TIP122, TIP125, TIP126 and TIP127.
Key electrical characteristics include absolute maximum ratings such as collector‑emitter voltage up to 100 V, collector current up to 5 A, and total power dissipation up to 65 W at 25 °C. Thermal resistance, breakdown voltages, saturation voltages, and gain parameters are also listed, along with typical operating conditions.
| Package | TO-220 Plastic |
|---|---|
| Maximum collector current (Ic max) | 5.0 A |
| Maximum power dissipation | 65 W |
| Collector‑emitter voltage (VCEO max) | 60 V / 80 V / 100 V |
| Junction temperature (Tj max) | 150 °C |
The maximum collector current is 5.0 A.
The devices can dissipate up to 65 W at a case temperature of 25 °C.
They are supplied in a TO‑220 plastic package.
VCEO max is 60 V for TIP120, 80 V for TIP121, and 100 V for TIP122 (and similarly for the PNP devices).
