DESCRIPTION
The BRT21, BRT22, BRT23 product family consists of AC
switch optocouplers with zero voltage detectors with two
electrically insulated lateral power ICs which integrate a
thyrister system, a photo detector and noise suppression at
the output and an IR GaAs diode input.
APPLICATIONS
• Industrial controls
• Office equipment
• Consumer appliances
High input sensitivity is achieved by using an emitter
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/μs.
AGENCY APPROVALS
• UL file no. E52744 system code H
• DIN EN 60747-5-2 (VDE 0844)/DIN EN 60747-5-5
(pending) available with option 1
The zero cross line voltage detection circuit consists of two
MOSFETS and a photodiode.
• CQC
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 thyristers or TRIAC and
relays.
