Description:
The DIH-1378 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. One is normally closed (N/C) and the other is normally opened (N/O).
Both relays are built with separate input LEDs and optically isolated power MOSFET outputs. The N/C and N/O outputs
are able to operate either AC or DC. Connecting the two inputs either in series or parallel (depending on available power
supply) will convert the (N/C), (N/O) of DIH-1378 from 2 single SPST relays into a single SPDT configuration.
Each relay, A or B, is capable of carrying 150mA AC or DC continuous current and 250mA 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 output MOSFETs, thus controlling their current. The DIH-1378 is also
available screened to military specifications, as required.
