Power MOSFET Optocoupler SPST Normally Closed

Power MOSFET Optocoupler SPST Normally Closed
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.
