Pinout of 2SD1624

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

Classification of hFE

The 2SD1624 transistor can have a current gain of 100 to 560. The gain of the 2SD1624-R will be in the range from 100 to 200, for the 2SD1624-S it will be in the range from 140 to 280, for the 2SD1624-T it will be in the range from 200 to 400, for the 2SD1624-U it will be in the range from 280 to 560.


Sometimes the "2S" prefix is not marked on the package - the 2SD1624 might only be marked "D1624".
