Solid-state relays typically have an isolation barrier between the primary and secondary sides of the device that can be achieved with various insulation materials. Refer to Table 2-1 for more information.
Isolation Type | Insulation Material | Dielectric Strength (1s) | Operating Temperature |
---|---|---|---|
Optical Isolation | Epoxy or Polyimide |
approximately 20VRMS / µm approximately 300VRMS / µm |
-40°C - 85°C |
Inductive Isolation | Laminate or Polyimide | approximately 300VRMS / µm | -40°C - 125°C |
Capacitive Isolation | Silicon Dioxide | approximately 500VRMS / µm | -40°C - 125°C |
