Micropac Industries, Inc. Power Switching solid state relays 53115

The 53115 is a single channel, hermetically sealed, power MOSFET optocoupler. Low onresistance 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. Lead options support both through-hole and surface-mount assembly. Standard lead finish is gold plated. Functionally, the device operates asa 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 ofsubstantial reduction in onresistance and twice the output current capability as that obtained with connection A.
