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

Classification of hFE

The 2SB548-P transistor can have a current gain of 160 to 320. The gain of the 2SB548 will be in the range from 40 to 320, for the 2SB548-Q it will be in the range from 100 to 200, for the 2SB548-R it will be in the range from 60 to 120, for the 2SB548-S it will be in the range from 40 to 80.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB548-P might only be marked "B548-P".

Complementary NPN transistor

The complementary NPN transistor to the 2SB548-P is the 2SD414-P.

SMD Version of 2SB548-P transistor

The 2SA1368 (SOT-89), 2SA1368-E (SOT-89), 2SB805 (SOT-89) and 2SD1006 (SOT-89) is the SMD version of the 2SB548-P transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
