Would a LCA110 DIP-6 solid state relay work for switching 330v DC? I cannot find information on the datasheet of whether or not this is suitable for switching 330 volts DC. I am using it to switch 5 80uf 330v capacitors into a coil for a coilgun, using an Arduino.

It's right there at the top of the DS: -

However, If you think it's going to survive your application I'd think again. Here's the hint - look at the load current.

  • \$\begingroup\$ Doubt it ... 330V, 35 ohms, call it 10A, 3kw. Subtract a guess for the coilgun inductors and it's still worth filming for Youtube... \$\endgroup\$
