Market Demands
  • Vacuum Cleaner (VC) power/speed control by using phase control with triacs
  • Minimise the use of relays
  • Prolonged VC use can lead to a high temperature of the power components, need for high Tj(max)  of 150ºC
  • Electrical motors are inductive, requiring 3 Quadrant triacs or ACTT
  • Low EMI
  • SMD packages for ease of board production
