Radiation Tolerant, 90V - 0.8A Dual Power MOSFET Optocoupler

Radiation Tolerant, 90V - 0.8A Dual Power MOSFET Optocoupler
The 53253 is two power MOSFET optocouplers in a single 8-pin dual-in-line package suitable for applications where two independent switches and radiation tolerant performance are required. The popular hermetic eight-pin dual-in-line ceramic package combined 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.
