PNP Transistors for AF power stages up to 20 W

AD 149 and AD 150 are germanium PNP alloyed transistors in a TO-3 package. The collector is electrically connected to the case. For insulated mounting of these transistors on a chassis, the insulating parts Q 62901-B 11-A and Q 62901-B 13-B are provided. These parts have to be ordered separately.
AD 149 and 150 are recommended for use in high-quality AF power stages. For use in push-pull power stages, these transistors are also available in pairs.
