Please help with discreet SSR

[Ravenloft]

Hello,
I am looking for help designing a discreet SSR.

The circuit will be used to control a 12Vrms output. The voltage drop needs to be very low (less than 0.2v) across the output contacts). The max load current is 6A rms.

The input control signal will be 5v DC, but I can level shift it up to 12 volts if needed.

I've seen optically isolated SSRs, but I would like to use a discreet solution.

Can someone help with circuit ideas?

Thanks!

Here is one that doesn't use optical isolation:

I wouldn't consider this circuit "safe" for 120VAC use, but 12Vac should be fine.
