Here is an image showing the pin diagram of this transistor.The 2SC3420-GL transistor can have a current gain of 200 to 400. The gain of the 2SC3420 will be in the range from 140 to 600, for the 2SC3420-BL it will be in the range from 300 to 600, for the 2SC3420-GL it will be in the range from 200 to 400, for the 2SC3420-Y it will be in the range from 140 to 240.Sometimes the "2S" prefix is not marked on the package - the 2SC3420-GL might only be marked "C3420-GL".You can replace the 2SC3420-GL with the 2SC2270, 2SC6101, 2SC6102, 2SD1685 or 2SD826.
