Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. Input-to-output peak voltage is the internal device dielectric breakdown rating. 2. Derate linearly to 100°C free-air temperature at the rate of 1.33 mW/°C. 3. Derate linearly to 100°C free-air temperature at the rate of 4 mW/°C. 4.

NOTE 5: Test voltage must be applied at a rate no higher than 12 V/µs.

NOTE A. The critical rate of rise of off-state voltage, dv/dt, is measured with the input 0 V. The frequency of Vin is increased until the phototriac turns on. This frequency is then used to calculate the dv/dt according to the formula:

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.
