i am designing a simple h-bridge. I am using tip41 npn power transistor and 2N2955 PNP transistor in the circuit, as you can see in the attached diagram...
as we know h-bridge are basically used for controlling the direction polarity of a motor.. So my question is,
as i am using a tip41 power transistor and its collector-emitter maximum voltage is 40V, collector-base voltage is also 40V and max. collector current is 6A.
and 2N2955 whose collector-emitter maximum voltage is 60V, collector-base voltage is also 100V and max. collector current is 7A.
so of what maximum rating of motor we can control using these rating of transistors? and please have a look on my circuit diagram is it need any changes..
Also, do we need safety for the transistor from voltage spikes?
