Hi there
I am wondering if someone out there knows how much the 2n3055 requires to be fully on (saturated)
Having a look at the datasheet is says - Collector−Emitter Saturation Voltage − VCE(sat) = 1.1 Vdc (Max) @ IC = 4 Adc
Does this mean that it is saturated at 4a 1v? What if the voltage is at 12v or higher?
4 ampres at 1v is 4w so does this mean that it only requires a total of 4w (at any voltage) ?
I need to know this as I am driving a pair of them with the output of an lm317 variable voltage regulator and want to know if the 1.5a supplied by this i.c is enough to make the 2n3055 fully open.
If these 2n3055 transistors require more power to open them up would it be better to put lm317's in parallel to get more power or better to use a couple of mosfets or jfets after the lm317 as a pre amp?
Any help appreciated I have asked about this on a previous post but stopped getting replies perhaps I was asking too many questions.
Regards-
Damien
