NOTE A. The critical rate of rise of off-state voltage, dv/dt, is measured with the input of 0 volts. The frequency of Vin is increased until
the phototriac turns on. This frequency is then used to calculate the dv/dt according to the following formula:
ń + ^Ǹ dv dt 2 2 pfVin
The critical rate of rise of commutating voltage, dv/dt(c), is measured by applying occasional 5-volt pulses to the input and
increasing the frequency of Vin until the phototriac remains on (latches) after the input pulse has ceased. With no further input
pulses., the frequency of Vin is then gradually decreased until the phototriac turns off. The frequency at which turn-off occurs
can then be used to calculate the dv/dt(c) according to the formula shown above.
