I have misplaced my c4s kit document, so does anyone know what the minimum voltage drop across the c4s?
Thanks

I think you'd want at least 5V, but the voltage needed across the C4S depends a whole lot more on what you're doing with it.

Thanks. That should be ok then. It is in a low voltage setup of 40v with a vfet at 6ma. The vfet + cathode bias should be about 19 to 20v which would leave 20v for the c4s voltage drop and the voltage swing. if it is only 5v it should leave plenty.
