so we can make double current using two transistor in parallel with same base bios..............great ...........all we have to take in account same temperature on both T
The last is quite easy to to do by putting the transistors on the same heat sink. The same temperature is important to have the same Vbe for both of the transistors. The same current for both depends on the tolerance of the resistors. For 1% resistors you get at worst 2% current difference between them. This corresponds well with the 20 mA current difference at 2 A, which is 1% of the total current.
