Pinout of 2SC3746

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

Classification of hFE

The 2SC3746 transistor can have a current gain of 70 to 280. The gain of the 2SC3746-Q will be in the range from 70 to 140, for the 2SC3746-R it will be in the range from 100 to 200, for the 2SC3746-S it will be in the range from 140 to 280.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SC3746 might only be marked "C3746".

Complementary PNP transistor

The complementary PNP transistor to the 2SC3746 is the 2SA1469.
