51. AC SSR Heater Control
Neha is designing a temperature control board to switch a 230VAC heater.
The heater current is 3A.
The relay will be driven from a 5V control signal.
Because the load will switch frequently, she wants a solid state relay for silent operation and long life.
Help her select a suitable SSR from DigiKey.
Make sure it supports the 5V control signal, can safely switch the 230VAC heater current, and is suitable for frequent ON/OFF operation.
