Optocoupler VISHAY BRT23F featuring GaAs IRLED and zero crossing detector for isolation of low voltage logic from AC lines

Product Overview

The BRT21, BRT22, BRT23 is an optocoupler featuring an optically coupled GaAs IRLED to a photosensitive thyristor system. It includes integrated noise suppression and a zero crossing circuit, enabling low trigger currents of 1.2 mA and high dV/dt ratios of over 10 kV/s with load voltages up to 800 V. This product family offers a microcontroller-friendly solution for isolating low-voltage logic from high-voltage AC lines (120 VAC, 240 VAC, 380 VAC) and controlling various AC loads such as motors, solenoids, high-power thyristors, TRIACs, and solid-state relays. Key advantages include low trigger current, high static dV/dt, 800 V load voltage, and a zero voltage crossing detector.
