What is the membrane potential range at which the voltage-gated Ca++ channels are open?

According to Guyton's, for the voltage-gated Na+ channels, at voltage range ]-90mV,+35mV[, the activation gate starts to open while the inactivation gate starts to close, only that the inactivation gate is a few 10,000th of a second slower, allowing the influx of Na+.

What about Ca++

Although there is this answer from: http://www.physiologymodels.info/autorhythmic/calcium.htm

Calcium channels open when the the threshold potential is reached
