Panasonic has produced a 6pin DIP-style opto-relay that can switch 1.2kV at 750mA.

Called AQV209G, it comes in through-hole and surface-mount versions and has a single ac-dc output with two mosfets that can be wired back-to-back series to switch ac (‘A’ connection), or in parallel to switch dc at higher current (‘C’ connection).
