DESCRIPTION
 Consumer appliances
The BRT21, BRT22, BRT23 product family consists of AC 
switch optocouplers with zero voltage detectors with two 
AGENCY APPROVALS
electrically insulated lateral power ICs which integrate a 
thyrister system, a photo detector and noise suppression at 
 UL 1577
the output and an IR GaAs diode input.
 cUL 1577
High input sensitivity is achieved by using an emitter 
 DIN EN 60747-5-5 (VDE 0884-5) available with option 1
follower phototransistor and a SCR predriver resulting in an 
LED trigger current of less than 2 mA or 3 mA (DC). Inverse 
 
parallel SCRs provide commutating dV/dt greater than 
 
10 kV/s.
 
The zero cross line voltage detection circuit consists of two 
 
MOSFETS and a photodiode.
 
The BRT21, BRT22, BRT23 product family isolates 
 
low-voltage logic from 120, 230, and 380 VAC lines to 
 
control resistive, inductive or capacitive loads including 
motors, solenoids, high current thyristors or TRIAC and 
relays.
