Power MOSFET Optocoupler 480V / 0.28A / 0.55A, AC / DC, Hermetically Sealed

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.
