Description:
The DIH-1380 is a State-of-the-Art Photovoltaic Solid State Relay designed for special AC-DC switching power
applications where package space efficiency and high reliability are critical.
Each package contains two independent relays, controlled by a single input. One relay is normally closed (N/C) and the
other is normally open (N/O). The relays are built with their input-LEDs internally connected in series and optically
coupled to their power-MOSFET outputs. The N/C and N/O outputs are able to operate either AC or DC.
Each relay, A or B, is capable of carrying 200mA AC or DC continuous current and 350mA DC peak current. Each LED
optically couples to a Photovoltaic (PV) IC chip which responds by generating a voltage. This voltage is internally
connected to the Gate and Source terminals of the MOSFET outputs, thus controlling their current. The DIH-1380 is also
available screened to military specifications, as required.
