DESCRIPTION

The BRT21, BRT22, BRT23 product family consists of an

optically coupled GaAs IRLED to a photosensitive thyristor

system with integrated noise suppression and zero crossing

circuit.

The thyristor system enables low trigger currents of 1.2 mA

and features a dV/dt ratio of greater than 10 kV/μs and load

voltages up to 800 V.

The BRT21, BRT22, BRT23 product family is a perfect

microcontroller friendly solution to isolate low voltage logic

from high voltage 120 VAC, 240 VAC, and 380 VAC lines and

to control resistive, inductive, or capacitive AC loads like

motors, solenoids, high power thyristors, or TRIACs and

solid-state relays.
