Hello,
I am designing one of my regulator circuit using LM2678T-ADJ regulator. Now the thing I came up with is I want to turn on or off the whole regulator circuit using a biopolar transistor like 2N2222A with my Arduino UNO R3. But my regulator circuit will consume about 5A of current at peak but the 2N2222A is rated for 800mA only from the emiiter to the collector according to it's datasheet. So I tried looking on some mosfets like 2N3055 which are rated for higher current switching. But...
Which biopolar transistor to use for switching higher currents using microcontroller
