Description:

The DIH-134-SM is a State-of-the-Art Photovoltaic Solid State Relay designed for 28V DC Aircraft power applications

where speed, current overload protection and immunity to transient voltages are critical.

The DIH-134-SM contains current limiting networks and thermally sensitive integrated circuits that disable the output, if

the output MOSFETs approach an unsafe operating temperature. Because the thermally sensitive integrated circuits have

built-in hysteresis, the output MOSFETs are automatically restarted when a safe temperature is reached. This auto restart

feature eliminates the need for system restart signals. If the overload condition continues to exist, the cycle is repeated; if

the overload condition is removed, the relay returns to normal operation.

The gull-wing surface mount package contains two independent N/O relays, with separate LED inputs and optically

isolated power MOSFET outputs. Each relay, A or B, is capable of carrying 350mA DC continuous current and 500mA

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-134-SM is also available screened to military specifications, as required.
