Thanks for the transistor, it works great, and seems to have a faster switching time, I couldn't find MJ21194 in the market, but MJ15022 was found at about 2.5$ I bought six of them and unfortunately due to a mistake I semi-burnt three of them I suppose . Now I see that the neon is unable to protect these transistors even though these are able to operate around 200 volts, but when using a 24 volt system you have no hope but burn them all. So I certainly recommend the Zener protection for everyone, unless you want to spend $ for transistors!! I have decided to switch all of them to MJ15022 as they work wonderfully.
