Industrial Control Optocoupler IL4208-X017T with 800 Volt Blocking Voltage and High dVdt Protection
Product Overview
The Vishay Semiconductors IL420 and IL4208 are optocouplers featuring a GaAs IRLED optically coupled to a photosensitive non-zero crossing TRIAC network. They are designed for isolating low-voltage logic from AC mains lines, controlling various loads with high dV/dt and low input current sensitivity. The devices offer high input sensitivity (IFT < 2 mA), high blocking voltage (up to 800 V), and high static dV/dt (> 10 kV/s) due to a proprietary dV/dt clamp circuit. They are suitable for controlling resistive, inductive, or capacitive loads in applications such as solid-state relays, industrial controls, office equipment, and consumer appliances.
