I have a simple 555 timer circuit that I need to remove the relay from. Reason for this is #1 magnets in area affecting reliability and #2 lessen cost. The load is Aprox 1A @12Vdc but I want to have at lest 1.25A capability. I figure the TIP31 would be a good canadate since I will be switching the positive leg of the load. Here is a schematic of what I have can you assist me in removing the relay and inserting the transistor? I never studied much about transistors yet now I wish I had.
555 says 200ma Max load on output pin 3.
