DESCRIPTION
The 53259 is a single channel power MOSFET optocoupler. 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 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 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 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 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.
Applications:
• Satellite / Space Systems
• Military / High Reliability Systems
• Power Distribution Control
• AC/DC Electromechanical or Reed Relay
Replacement
• I/O Modules for Automated Test Equipment
• Process Control
• Telecom Applications
• Medical Electronics
