Ive recently built a timer for a 9v pulser using a picaxe 08m.I am using a 2N3906 to turn the power to the pulser on and off but I am not getting a full "turn off" (pulser still putting out 1-1.25v during "off" time.) I have a 2N4403(found it in the package of 3906) which has all the same characteristics as the 3906 but a higher ma rating on the collector current.(3906=200ma, 4403=600ma) If I was to use this instead, would I get a better "turn off"? for the pulser?
I have included the schematic for the timer.
