The document provides technical data for Motorola Bipolar Power Transistor devices TIP47, TIP48, TIP49, and TIP50.
These transistors are designed for line-operated audio output amplifiers, switch mode power supply drivers, and other switching applications.
They have a collector-emitter voltage range of 250V to 400V, a rated collector current of 1A, and come in a popular TO-220 plastic package.
The document also includes maximum ratings, thermal characteristics, and a power derating graph.
Additionally, it mentions that the preferred devices are Motorola recommended choices for future use and best overall value.
