They offer a cost-effective solution with excellent trade-off of surge current versus immunity and commutation. The package is also RoHS (2002/95/EC) compliant.
The 3-quadrant triacs cannot be turned on in the fourth quadrant which is favourable in applications with inductive loads.
All components are snubberless devices so a resistive/capacitive network is not necessary (if the datasheet limits are respected). The series provides an insulated tab (rated at 2500Vrms) and is UL certified (ref. file E81734).
The devices are intended for circuits where high static and dynamic dV/dt and high dI/ dt can occur.
Target applications include general purpose AC line load switching, home appliance, fan, pump, solenoid, lighting, heaters, inrush current limiting circuits and overvoltage crowbar protection circuits.
