ACS and ACST devices are now well known in the appliance world. The development of new products dedicated to specific loads provides global kits to the electronic designer who wants to provide robustness, immunity and new functions in systems. In parallel with the new device developments, the current versions of ACS are re-designed to benefit from the continuous improvements in the technology.
The well known ACS102-5Tx and ACS108-5Sx have been re-designed to improve the overall electrical performances of these high reliability switches. The new versions are ACS102-6Tx and ACS108-6Sx.
The voltage capability (VDRM/VRRM) has been increased from 500V to 600V. Therefore the crowbar structure starts to protect the system at a higher voltage level than the previous version, and the robustness has been re-qualified because the higher crowbar threshold voltage causes a higher energy that the switch must sustain.
The static characteristics have also been improved. The latching and holding levels have been drastically reduced (50% of the previous version), allowing a more optimized gate pulse control mode, especially in case of lower power rated loads, thus helping to save energy.
The dynamic characteristics also show enhanced performance. The switching capabilities and the electrical noise immunity have been improved by about 15%. This new performance gives a higher guard margin in case of specific load control.
This redesign of the ACS102 and ACS108 shows that this mature device family benefits from continuous design improvements, providing to electronic designers robust and immune solutions.
Main applications:
AC ON/OFF static switching in appliances and industrial control systems
Drive of low power high inductive or resistive loads like:
 
relay, valve, solenoid
 
dispenser, door lock
  micro-motor
Benefits:
Needs no more external protection snubber or varistor
Overvoltage crowbar technology
Enables equipment to meet IEC61000-4-5
Reduces component count up to 80 %
Interfaces directly with the micro-controller
Common package tab connection allows connection of several ACS on same cooling pad
