ambient temperature unless otherwise specified Pin configuration 1 = Base, 2 = Emitter, 3 = Collector. SOT-23 4/98 PNP Silicon Epitaxial Planar Transistors especially suited for application in class- B video output stages of TV receivers and monitors. As complementary types, the NPN tran- sistors BF820 and BF822 are recommended.
