FOD410S

The FOD410S from ON Semiconductor is a high-performance optoisolator designed for Triac and SCR output applications. It integrates an infrared emitting diode with a hybrid triac, making it suitable for driving discrete triacs in various control systems.

Key electrical specifications include a high blocking voltage of up to 600V (or 800V for specific variants), a peak on-state current of 300mA, and a high static dv/dt rating of 10 kV/µs. The device also features a zero-voltage crossing circuit, which is crucial for minimizing electromagnetic interference in AC power control applications. Its high trigger sensitivity ensures reliable operation.

This optoisolator is housed in a standard 6-pin dual in-line (DIP) package, specifically a 6-SMD, Gull Wing configuration, suitable for surface mounting. The operating temperature range is from -55°C to 100°C, providing robustness for industrial environments. Safety and regulatory approvals include UL1577 and DIN-EN/IEC60747-5-5, with isolation voltages up to 5000Vrms.

Applications for the FOD410S include solid-state relays, industrial controls, lighting controls, static power switches, and AC motor starters. Its combination of high voltage, current handling, and isolation makes it a versatile component for power control circuits.
