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.
