Description:
DIH-126, DIH-127 and DIH-136 are State -of-the-Art AC-DC Photovoltaic (PV) Solid State Relays designed for A.T.E.
applications where speed, power, on-resistance and leakage current are critical. These PV relays incorporate an infrared
LED input, a PV diode array connected to the gates of 2 pairs of power MOSFETs as output and a unique turn-off circuit.
The PV diode array is 2 series-connected groups of photosensitive diodes, which are electrically isolated from, but
optically coupled to the input LEDs. When activated, each LED emits infrared light toward the PV 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 power 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.
DIH-126, DIH-127 and DIH-136 are specific PV relays that are produced from one basic semi-custom design. Options,
such as: current limiting, thermal protection, short circuit protection, status indication, constant current input or ultra fast
switching may be incorporated into customized versions of these relays
