Description

The isolated self-powered AC solid state relay with MOSFETs reference design is a relay replacement that enables efficient power management for a low-power alternative to standard electromechanical relays. The galvanic isolation is implemented capacitively, creating a cost-efficient, reduced footprint solution for multiple relay replacement in thermostats and other similar equipment.

Features
  • No clicking sound
  • Galvanic isolation
  • Self-powered
  • Zero power from thermostat battery
  • Inherent snubber circuit reducing voltage spike created by inductive loads
