DESCRIPTION
The 53111 is a single channel, hermetically sealed, power MOSFET optocoupler. Low on-resistance of the
MOSFET output, combined with 1500 VDC isolation between input and output, makes this optocoupler ideal for
solid state relay applications. Operation is specified over the full military temperature range. The part is supplied in
an eight-pin, dual-in-line ceramic package, available as COTS, as fully compliant MIL-PRF-38534 Class H device,
or with custom screening. Lead options support both through-hole and surface-mount assembly. The part is
normally shipped with gold plated leads, but lead finishes per MIL-PRF-38534 are available.
Functionally, the device operates as a single-pole, normally open (1 Form A) solid state relay. The device is
actuated by an input current, which can be supplied from standard logic types such as open-collector TTL. The
input current biases a light emitting diode that is optically coupled to an integrated photovoltaic diode array. The
photovoltaic array powers control circuitry that operates the output MOSFETs.
Optimum switching of either AC or DC loads is provided by a configurable output. For AC loads, connection A in
Figure 1 must be used. Connection A will also switch DC loads but connection B, in Figure 1, provides DC-only
operation with the advantages of substantial reduction in on-resistance and twice the output current capability as
that obtained with connection A.
