The 8550 is a Silicon PNP transistor housed in a TO-92 plastic package. It is designed for high collector current (IC) and collector power dissipation (PC), serving as a complementary pair to the 8050 transistor. This device is ideal for 2W output amplifiers in portable radios utilizing class B push-pull operation.
