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.

Notes:

2. During the pulsed R

measurement (I
O
duration < 30 ms), ambient (T
A
) and case temperature (T
C
) are equal.
3. This is a momentary withstand test, not a continuous operating condition.
4. Typical junction to case thermal resistance (
JC
) for the device is 15C/W, where case temperature (T
C
) is
measured at the center of the package bottom.
CAUTION:
Care should be taken not to exceed the maximum output power dissipation, maximum case temperature, and
maximum junction temperature when repetitively switching loads.
