Operating and Storage Junction Temperature Range: -55 to +150 °C
Package: TO-92
Pinout of 2SD471K
The 2SD471K is manufactured in a plastic TO-92 case. When looking at the flat side with the leads pointed downward, the three leads emerging from the transistor are, from left to right, the emitter, collector, and base leads. Here is an image showing the pin diagram of this transistor.
Classification of hFE
The 2SD471K transistor can have a current gain of 200 to 400. The gain of the 2SD471 will be in the range from 90 to 400, for the 2SD471L it will be in the range from 135 to 270, for the 2SD471M it will be in the range from 90 to 180.
Marking
Sometimes the "2S" prefix is not marked on the package - the 2SD471K might only be marked "D471K".
Complementary PNP transistor
The complementary PNP transistor to the 2SD471K is the 2SB564K.
