Pinout of 2SB950-P

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

Classification of hFE

The 2SB950-P transistor can have a current gain of 4000 to 10000. The gain of the 2SB950 will be in the range from 2000 to 10000, for the 2SB950-Q it will be in the range from 2000 to 5000.


Sometimes the "2S" prefix is not marked on the package - the 2SB950-P might only be marked "B950-P".

Complementary NPN transistor

The complementary NPN transistor to the 2SB950-P is the 2SD1276-P.
