Dual photovoltaic MOSFET delivers open circuit voltage of 12.2V

The MOSFET is controlled by an nfrared LED at the input, whilst the PV array is capable of generating a floating power source with voltage and current sufficient to drive high-power MOSFET transistors. The device can achieve a 27uA short circuit current with a higher input LED current of 30mA.  The independent outputs can be connected in parallel to deliver a short circuit current of 18.2uA with a forward LED current of 10mA.  Alternatively, the outputs can be stacked in series to deliver an open circuit voltage greater then 24.4V. 

Eliminating the need to use external components to facilitate discharge, each PV array contains an integrated turn-off circuit that discharges the external MOSFET gate when LED current is removed. The optically coupled technology provides 3750Vrms of input to output isolation.

The device can be used in solid state relay designs, in controlling electrical power and loads to reduce energy waste, and in other isolated switching applications. Further to this, the device has been designed for use with the Zilog family of MCUs for digital power control that matches the demand profile of specific applications, such as in industrial process control, factory and home automation. The device is certified to EN/IEC 60950 by TUV.
