Returned to hobbyist electronics, and already stuck

[PhilWainwright]

Hi there, this is my first post, so; nice to make your acquaintance, and also I would like to ask for a bit of help.

(The last time I did hobby electronics was about 30 years ago, so need to wake the old brain cells up. Anyhow, I am playing with an idea, and in order to make it work, I am going to need a reasonably high power output (20 amp ish at 12v)

I have a 0-10v source signal.

So I have ordered one of these, 600V 30Amp High Power Switching Silicon Transistor MUR3060PT. So could someone please suggest a basic circuit whereby I could feed my source signal in, and have a higher current rated output at 12v?

I would just like to initially understand the function of the component. Then I can draw a circuit with overload protection etc in place once I know where the pins go

Thank you all

What is it for? Are you needing a ratio of output current to input current or will an ON/OFF do? Do you need isolation between the 0-10v signal and the 12v supply? I'm wondering if an opto-relay will be the correct part for the job.

[PhilWainwright]

I do not need any proportional output. Simply on/off. I have a 30 amp power supply, so maybe a high current opto relay could work... I will be using frequencies upto 200 kHz.... if that helps?

i have many drills i can use. both battery and mains (uk) powered. what is the best to generate dc power? somewhere around 12v for a few low watt lights and maybe battery charging.
