Alternating current mains switch - basic application

The ACS108-8TN switch is triggered by a negative gate current flowing from the gate pin

G. The switch can be driven directly by the digital controller through a resistor as shown in

Figure 16: "Typical application schematic".

Thanks to its over-voltage protection and turn-off commutation performance, the

ACS108-8TN switch can drive a small power high inductive load with neither varistor nor

additional turn-off snubber.

Protection against overvoltage: the best choice is ACS

In comparison with standard Triacs the ACS108-8TN is overvoltage self-protected, as

case of turn-off of very inductive load, and in case of surge voltage that can occur on the

electrical network.
