BGA-packaged SMT optocoupler
The FODB100 Microcoupler is said to be the first single-channel optocoupler with a transistor output housed in a BGA (ball grid array) package designed for consumer electronics, such as chargers, adapters, set-top boxes and appliances, as well as for industrial applications, such as power supplies and motor controls.?
The device comes in a 3.5 mm x 3.5 mm package with a profile of 1.20mm (maximum mounted height), and has a operating temperature range of -40∫C to +125∞C.? The single-channel optocoupler consists of an aluminum gallium arsenide infrared light emitting diode driving a silicon phototransistor. Featuring high isolation (2500 Vrms for 1 s) and high current transfer ratio at low input current levels, the Microcoupler is designed for conventional voltage isolation in power system feedback circuits and for isolating signals in high-voltage, electrically noisy environments.
