Description

DRM
The BRT21, BRT22, BRT23 product family consists
of AC switch optocouplers with zero voltage detec-
tors 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
High input sensitivity is achieved by using an emitter
follower phototransistor and an SCR predriver result-
ing 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

THe BRT21/ 22/ 23 product family isolates low-volt-
age 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.
