ACT108W-600D
AC Thyristor power switch
15 June 2016 Product data sheet
1. General description
AC Thyristor power switch in a SOT223 surface-mountable plastic package with self-protective
capabilities against low and high energy transients
2. Features and benefits
• Common terminal on mounting base allows multiple ACTs on shared cooling pad
• Exclusive negative gate triggering
• Full cycle AC conduction
• High noise immunity
• Remote gate separates the gate driver from the effects of the load current
• Surface-mountable package
• Very sensitive gate for lowest gate trigger current
• Safe clamping of low energy over-voltage transients
• Self-protective turn-on during high energy voltage transients
3. Applications
• Fan motor circuits
• Pump motor circuits
• Lower-power highly inductive, resistive and safety loads
