Low on-resistance of the MOSFET outputs, combined with 1500 VDC isolation between input and output, makes this optocoupler ideal for many solid state relay applications. Operation of 53259 is specified over the full military temperature range. The part is supplied in an eight-pin, dual-in-line ceramic package, available in variety of quality levels from COTS to class K including any custom screening requirements. The basic data sheet part is environmentally screened to H level in accordance with Table C-IX of MIL-PRF-38534. For ordering part number; consult with Micropac factory for detail. The 53259 is normally shipped with gold plated leads, but lead finishes per MIL-PRF-38534 are available.
Functionally, the 53259 operates as a single-pole, normally closed (1 Form B) 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 of 53259 powers control circuitry that operates the output MOSFETs.
Optimum switching of either AC or DC loads is provided by a configurable output of 53259. 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.
