BRT21 General Description
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/s
The zero cross line voltage detection circuit consists of two MOSFETS and a photodiode. 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.
BRT21 Maximum Ratings
Tamb = 25, unless otherwise specifie Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute Maximum Rating for extended periods of the time can adversely affect reliability.
