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
