The ISO-GATETM is a state-of-the-art optoisolator incorporating DIONICS’ photovoltaic (PV) diode arrays and an infrared LED. The diode array is a unique I.C. consisting of series-connected photovoltaic diodes. The diodes are completely isolated from each other and from their common substrate by means of SiO2 Dielectric Isolation (DI). These photovoltaic output chips are electrically isolated but optically coupled to the LED. The typical input circuit to the LED is a limiting resistor connected in series with the LED. When activated, the LED emits infrared light towards the photovoltaic diode array, which then responds by generating an open circuit voltage (Voc). This Voc is floating and is therefore completely isolated. The Voc value depends on the LED input drive and load impedance. DIONICS, Inc offers a wide variety of package styles including low-cost plastic Mini-DIP’s, high reliability TO-5 metal cans, 8-pin ceramic side brazed DIP’s and ceramic chip carriers for hybrid manufacturers. Other custom packages and custom designs are also available. o o Group I: DIG-11-06-030; DIG-11-06-150; DIG-11-08-050.
