Pinout of 2SD545-F

The 2SD545-F 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 2SD545-F transistor can have a current gain of 160 to 320. The gain of the 2SD545 will be in the range from 60 to 560, for the 2SD545-D it will be in the range from 60 to 120, for the 2SD545-E it will be in the range from 100 to 200, for the 2SD545-G it will be in the range from 280 to 560.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SD545-F might only be marked "D545-F".

Complementary PNP transistor

The complementary PNP transistor to the 2SD545-F is the 2SB598-F.
