DESCRIPTION
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.
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.
RADIATION TOLERANT
This device contains radiation hardened components and/or other features that provide a level of radiation tolerance.
Micropac does not guarantee any level of radiation hardness. Specific lot testing is required to determine the level of
radiation hardness. Micropac does not offer this device as compliant to Appendix G (RHA Requirements) of MIL-PRF-
38534.

) is maintained below 120°C.
During the pulsed R
ON
measurement (I
O
duration < 30 ms), ambient (T
A
) and case temperature (T
C
) are equal.
This is a momentary withstand test, not a continuous operating condition.
Typical junction to case thermal resistance (
JC
) for the device is 15°C/W, where case temperature (T
C
) is
measured at the center of the package bottom.
