Power MOSFET Optocoupler, 90 V / 1, Hermetically Sealed

Power MOSFET Optocoupler, 90 V / 1, Hermetically Sealed
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.
