Product Description
Product Overview
The VOT8121AM is an optocoupler featuring a GaAs IRLED coupled to a photosensitive TRIAC in a space-saving SOP-4 package. It provides isolation for low-voltage logic from AC lines (120 VAC, 240 VAC, 380 VAC) and is suitable for controlling various loads including motors, solenoids, high current thyristors/TRIACs, and relays. Key advantages include high static dV/dt, high input sensitivity, and a low input current requirement.
