Selb, Germany Vishay Intertechnology has announced the VO3062 and VO3063 , two zero crossing 1.5 kV/µs dV/dt phototriacs designed to isolate low-voltage logic from ac voltages up to 380 V. The phototriacs consist of a GaAs infrared LED that is optically coupled to a monolithic photosensitive zero crossing triac detector chip. A low-input trigger current facilitates an easy interface with microcontrollers and digital logic. The VO3063 requires a maximum trigger current of 5 mA to latch output, while the VO3062 requires a maximum trigger current of 10 mA. The devices are available in 6-pin DIP, 400-mil DIP, and SMD packages. Rated with a 600 V blocking voltage, the phototriacs can provide isolation between dc and ac voltages on 120 V, 240 V, and 380 V AC lines, giving designers a 2X or better safety factor for control of off-line voltages up to 240 V. The VO3062 and VO3063 are designed for control of resistive, inductive, or capacitive loads including motors, solenoids, high-current thyristors, and relays. The VO3062 and VO3063 are direct replacements for industry-standard 1.0 kV/µs dV/dt phototriacs. Optimized for noisy environments, typical applications for the devices will include refrigerators, air conditioners (HVAC), dishwashers, vending machines, industrial controls, ac motor drives, switches, switching power supplies, and solenoid/valve controls. Samples and production quantities of the new phototriacs are available now, with lead times of six to eight weeks for larger orders. Vishay Electronic GmbH , Selb, Germany. www.vishay.com.
