Hello...

Can any body tell me about any commercial IC that can be used as a relay for 600V 500mA at 150 Hz ?
I need to control it via microcontroller.. Please see the attached file.

Thank in advance

Regards
Salman

I think the 150Hz refers to the maximum switching speed, not the 600V frequency. The 600V is DC according to the diagram, am I correct?

If so, a triac won't turn off.

How about an IGBT? For instance, the NGTB15N120FL from OnSemi, or a power MOSFET, e.g. the NDD03N80Z from OnSemi. I like OnSemi!

Do you really need to switch the negative rail as well?
