Description:
DIH-129, DIH-149 and DIH-169 are State-of-the-Art AC-DC Photovoltaic (PV) Solid State Relays designed for power
management 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-129, DIH-149 and DIH-169 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
