The Vishay BRT21H is an AC optocoupler featuring a phototriac output and non-zero voltage detection. It integrates a thyristor system, photo detector, and noise suppression within two electrically insulated lateral power ICs, driven by an IR GaAs diode input.
Key electrical characteristics include an RMS current rating (I TRMS) of 300 mA and a high static dV/dt of over 10,000 V/μs. The device is designed for microcomputer compatibility with a low trigger current (IFT < 2 mA for BRT11H, BRT12H, BRT13H variants). The VDRM rating is up to 400V for the BRT11H variant.
This optocoupler is available in a 6-SMD surface mount package. Its design makes it suitable for applications requiring electrical isolation between input and output circuits, such as industrial controls, office equipment, and consumer appliances.
Agency approvals include UL 1577, cUL, and DIN EN 60747-5-5 (VDE 0884-5).
