Do I really need to? What are the advantages?
A solid state relay offers more working hours and can switch faster. If you want to just switch a DC device on/off you can use a MOSFET, an IGBT, a BJT or a GTO.Do I really need to? What are the advantages?
1. You can use a TIP1201: Can I use a TIP120 intead of a TIP102? I think I can but just to make sure?
2: Can I use a 1N4001 or 1N4002 or a group of them instead of a 1N4007? I DON'T think I can but????
