The popular hermetic eight-pin dual-in-line ceramic package bined with 1000 VDC isolation between input and output and between two isolated relays, makes this device ideal for solid-state relay applications. Performance is specified over the full military temperature range. This device is available as COTS, or screened to MIL-PRF-38534, Table C-IX, Class H or custom screening. Lead options support both through-hole and surface-mount assembly. Gold plated leads are standard, but other lead finishes per MIL-PRF-38534 are also available. Functionally, the device operates as two SPST, normally open (2 Form A) solid-state relays. Each relay is actuated by an input current, which can be driven from a standard TTL device. The input current biases a light emitting diode that is optically coupled to an integrated photovoltaic diode array. The photovoltaic diode array energizes control circuitry that operates the output MOSFET. Micropac Industries cannot assume any responsibility for any circuits shown or...
