Maximum frequency handling capacity or the transition frequency is 250 MHz for 2N2222 and 300 MHz for 2N2222A.hFE or the dC current gain of 2N2222 transistors will be around 7 5 minimum, at voltages near 10, with 10 mA collector current.Total power dissipation of the device should not exceed above 500 mW.As expressed earlier, the maximum current that can be applied across the transistors collector and emitter, via a load is not more than 800 mA. ![]()
