NOTE A. The critical rate of rise of off-state voltage, dv/dt, is measured with the input at 0 V. The frequency of Vin is increased until the
ń + Ǹ phototriac turns on. This frequency is then used to calculate the dv/dt according to the formula:
dv dt 2 2πfVin
The critical rate of rise of commutating voltage, dv/dt(c), is measured by applying occasional 5-V pulses to the input and increasing
the frequency of Vin until the phototriac stays 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 may then be used
to calculate the dv/dt(c) according to the formula shown above.
