Absolute ratings parameters

Parameter

Name and description

Repetitive peak off-state voltage (50-60 Hz)

This is the maximum peak voltage allowed across the device. This parameter is

specified up to the maximum junction temperature and the leakage currents,

Non repetitive peak off-state voltage

This is the maximum peak voltage allowed under pulse conditions across the

device. It is specify for pulse durations lower or equal to 10ms.This parameter

guarantees the ruggedness of the TRIAC in case of fast line transients

On-state rms current

This is the maximum rms current allowed in the device for a specified case

depending on the type of package.

Average on-state current (SCR only)

This is the maximum average current allowed in the SCR at a specified case

depending on the type of package

Repetitive peak on-state current

This is the maximum allowable repetitive peak current for a specified pulse

duration at a specified case, ambient or lead temperature and frequency.

Non repetitive surge peak on-state current

This is the maximum peak current allowed in the device under pulse conditions.

For TRIACs, it is defined for a single full cycle sine wave of 20 ms corresponding

to the 50 Hz mains, and 16.6 ms for the 60 Hz mains.

If the absolute rating is exceeded, the component may be damaged

dI/dt

Critical repetitive rate of rise of on-state current

During turn-on, the maximum rate of rise of current should not exceed this

maximum value. Above this limit, the SCR or TRIAC may be damaged

Value for fuse definition

To protect the device, the I²t rating of the fuse used in series with it must be

lower than this specified value.

Storage and operating junction temperatures

The storage temperature range is the range in which the device can be stored

(shipping, handling, storage...), without working.

The operating junction temperature range is the range at which the junction can

work without damage.
