The OC150HG is a high-voltage optocoupler with axial leaded epoxy molded packaging, designed for isolation between low-voltage control circuits and high-voltage sensing applications. It features an isolation test voltage of 25 kV between the LED and photodiode sections. The LED has a forward current rating of 100 mA, surge current capability of 1.0 A, and forward voltage of 1.5 V at 100 mA. The photodiode supports a reverse voltage of 15,000 V with a typical reverse leakage current of 250 nA at 15 kV and 25°C. The device operates from -40°C to +70°C and has a minimum DC current transfer ratio of 0.28% at LED current of 50 mA and photodiode reverse voltage of 15 kV. Turn-on and turn-off times are typically 2 µs.
Available in a clear molded package, VMI’s 10kV and 15kV version optocouplers are fabricated with two infrared LEDs. VMI’s 25kV optocoupler, the OC250 is assembled in shell with enough isolation to allow it to be operated in air without the need for additional insulation. All optocouplers are rated for 25kV isolation voltage between the LEDs and the high voltage diode.
Utilizing the photo-sensitive nature of silicon, VMI has created a line of high voltage optocouplers and opto-diodes. VMI’s optocouplers and opto-diodes are available in 10kV and 15kV versions and can be assembled in series configuration for additional standoff voltage capability.
