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 voltag...
