Description:  
The DIH-128 is a State-of-the-Art Photovoltaic Solid State Relay designed for A.T.E. applications where speed, on-  
resistance and leakage current are critical. These photovoltaic relays incorporate an infrared LED input, a photovoltaic  
(PV) diode array including a unique turn-off circuit connected to the gates of a pair of high voltage MOSFETs as output.  
The photovoltaic diode array is a series-connected group of photosensitive diodes, which are electrically isolated from,  
but optically coupled to, the input LED. Input/Output isolation is rated at 400 VDC.  
When activated, the LED emits infrared light toward the photovoltaic diode array, which then responds with a self-  
generated open circuit voltage, Voc, proportional to the LED input current. This Voc , which is floating and completely  
isolated from any power supply, is applied to the Gates of the MOSFETs. At the proper value of the input LED current,  
the generated Voc is sufficient to turn on the MOSFETs and cause the relay to conduct. The MOSFET outputs provide  
thermal stability, immunity from false turn-on, and low offset voltage.
