Data Sheet - OZ100SG - 10kV Opto-diode

New Technology Opto-diode Targets Custom High Voltage Opto-couplers.

Build your own high voltage opto-coupler in four steps using the OZ100SG and your choice of LEDs. Conceptually,

Varying forward current in the LED varies leakage current in the photo-diode.

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 of the LED will vary. Varying light intensity in the LEDs results in a corresponding variation in Ir in the photodiode. 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 photodiode.

Photo-diode reverse leakage 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%
(Io/Iled) x 100%

The optimum light wavelength has been experimentally determined to be

Between 890nm and 940nm

OZ100SG diodes are 100% tested for Ir, and forward voltage drop, Vf. The overall package is very small - .45” length x .180” x .180” {11.43 mm length x 4.57 mm width x 4.57mm height].
