The FOD4218 from ON Semiconductor is a high-performance optoisolator with a Triac output, designed for interfacing between electronic controls and power triacs to control resistive and inductive loads for 115 VAC operations. This robust device offers a practical solution for applications requiring isolated triac triggering, noise suppression, and the elimination of ground loops.

Key Features

• High Isolation Voltage: The FOD4218 provides an isolation voltage of 5300V peak, ensuring that the input signal is completely separated from the output, which is crucial for safety in high-voltage applications.
• High Static dV/dt: A minimum static dV/dt of 1000V/µs allows the FOD4218 to be used in applications with fast voltage transients, ensuring reliable operation under harsh conditions.
• Low Trigger Current: The device requires a low input trigger current, which makes it compatible with a wide range of driving circuits and microcontrollers.
• Zero Voltage Crossing: To minimize the effects of large inrush currents and noise, the FOD4218 includes a zero-crossing circuit that triggers the Triac only around the AC voltage zero point.
