New Products from VMI New Technology Opto-diode Targets Custom High Voltage Opto-couplers. From Voltage Multipliers Inc., comes the OZ100SG featuring high gain, excellent isolation voltage. OZ100SG Opto-diode and Opto-coupler Data Sheets The OZ100SG 10kV opto-diode makes it possible to build your own high voltage opto-coupler using your choice of LEDs as a light source in three easy steps. Reverse bias the photo-diode Run forward current through one or more LEDs, thus exposing the photo-diode junctions to light Monitor the leakage current, Ir, of the photo-diode. The level of Ir serves as feedback for the level of forward current through the LED while providing system isolation. Varying forward current in the LED varies leakage current in the photo-diode. OZ100SG Description of Operation The OZ100SG represents a breakthrough in opto-diode technology. Capable of operating at up to 10,000 volts reverse bias (10kV Vrwm) is it comprised of twelve active, stacked, silicon junctions. The key to operation is light sensitive junctions. Molded in optically clear epoxy, the OZ100SG is a light-sensitive device. When exposed to light, leakage current, Ir, is the result. Leakage current is directly proportional to light intensity, so by varying forward current through the LEDs, light intensity from the LED will vary. Varying light intensity in the LEDs results in a corresponding variation in Ir in the photo diode. Ir typically ranges from 1uA to 1nA range. Controlling the exposure to light makes it possible to control leakage current in the photo-diode, thus providing a closed feedback loop. This makes for a useful way to remotely monitor electronically sensitive systems. Other light sources can be used to generate leakage current in the photo diode. Photo-diode Reverse Leakage (Ir) is linear within stated operating parameters. Leakage current is directly proportional to Level of reverse bias, Vrwm Distance of the light source from the junctions Wavelength of the light source High Voltage Gain is defined as Opto-diode current divided by LED forward current x 100% The optimum light wavelength has been experimentally determined to be between 890nm and 940nm Specifications Vrwm = 10kV Io = 50mA Trr = 3000ns Dimensions .450” length x .180” x .180”l[11.43 mm length x 4.57 mm width x 4.57mm height] Pricing Contact VMI Sales for a quote Applications include High Voltage Switches and Remote Control Circuitry HV Linear Regulators Spectroscopy Pockels Cells OZ100SG diodes are 100% tested for Ir, and forward voltage drop, Vf.
