Pinout of 2SB546-Y

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

Classification of hFE

The 2SB546-Y transistor can have a current gain of 120 to 240. The gain of the 2SB546 will be in the range from 40 to 240, for the 2SB546-O it will be in the range from 70 to 140, for the 2SB546-R it will be in the range from 40 to 80.

Marking

Sometimes the "2S" prefix is not marked on the package - the 2SB546-Y might only be marked "B546-Y".

Complementary NPN transistor

The complementary NPN transistor to the 2SB546-Y is the 2SD401-Y.

SMD Version of 2SB546-Y transistor

The PBHV9115T (SOT-23), PBHV9115X (SOT-89), PBHV9115Z (SOT-223) and PBHV9215Z (SOT-223) is the SMD version of the 2SB546-Y transistor. These transistors are of the same type, have similar parameters and are designed for surface mounting.
