Here is an image showing the pin diagram of this transistor.

Classification of hFE

The 2SC3748 transistor can have a current gain of 70 to 280. The gain of the 2SC3748-Q will be in the range from 70 to 140, for the 2SC3748-R it will be in the range from 100 to 200, for the 2SC3748-S it will be in the range from 140 to 280.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SC3748 might only be marked "C3748".

Complementary PNP transistor

The complementary PNP transistor to the 2SC3748 is the 2SA1471.
