Transistor, Photovoltaic Output Optoisolators

Transistor or photovoltaic output optoisolators use light to transmit information across an electrical insulation barrier, usually for safety or functional reasons. They are distinguished from other optoisolator types by their use of a simple phototransistor or photovoltaic cell (solar cell) as an output device.

Opto-isolator

In photovoltaic mode, the diode acts like a current source in parallel with a forward-biased diode. in this case, the module is often called an optoisolator or opto-isolator. The photosensor may be a photocell, phototransistor, or an optically triggered SCR or Triac. Occasionally, this device will in turn operate a power relay or contactor.

I''d also consider the simplicity of using a photovoltaic opto isolator such as the Vishay VOM1271. It can switch on in 53 us into a 200pF load and produce a drive voltage of about 8V making it suitable for a lot of MOSFETs. Of course if the MOSFET gate capacitance is 2nF then it will take about 0.5 milli seconds to turn on.

Optoisolator

An optoisolator combines a photoconductor or a phototransistor with a high-quality, long-life light source in an encapsulated package that is light tight. The combination of various photosensors and light sources is available in a wide variety of packages. The main advantage to the use of an optical coupling device is that switching or variations in a circuit can be made without

Yes, there are photovoltaic cells driving depletion-mode MOSFETs. They are very slow in comparison to most optocouplers (hundreds of microseconds or milliseconds rather than microseconds or nanoseconds) but they do perform the function you ask about. Here is an IXYS (née Clare) one. In relay terms this is called a "Form B" contact.
