Additional Details:

The FODM3023M consists of an infrared LED and a triac driver in a compact surface mount package. When the LED is forward biased, it emits infrared light that activates the triac driver, allowing AC current to flow through the output circuit. The random phase operation allows for switching at any point in the AC cycle, which is useful for applications where precise timing is not critical. The high isolation voltage ensures safe operation in high-voltage environments. It is commonly used for switching AC loads such as lights, motors, and heaters. Operating temperature ranges from -40°C to +100°C.
