This all solid-state relay utilizes the
latest technology to provide a low ON
resistance. The control (input) and load
(output) are optically isolated to protect
input logic circuits from voltage and
current transients which can occur on
the output supply. The optical isolation
also provides a full floating output, thus
allowing the load to be connected to
either output terminal. The control circuit
is buffered to enable the relay to be
driven directly from standard CMOS or
open collector TTL logic circuits.
Available options include short circuit
and current overload protection, which
provides complete protection for both
the relay and the system wiring. This
feature not only provides protection
should a short or overload occur while
the relay is on, but will also provide
protection should the relay be switched
into a short. In either case, the relay will
sense the short circuit condition and
then block it indefinitely until the short is
removed and the unit is reset by cycling
the input control. The second option is a
status output, which provides a built-intest function. This feature checks the
input circuitry of the relay and provides a
logic (0) low when the input circuit is
turned on and operational. Both options
are available either together or
separately as standard features.

Control input is compatible with CMOS or open collector
TTL (with pull up resistor).
The rated input voltage is 5V for all tests unless otherwise
specified.
Transient blocking voltage tests are performed per
MIL-STD-704 (28 Vdc systems).
For bias voltages above 6V, a series resistor is required.
Use the standard resistor value equal to or less than the
value found from Figure 8.
To calculate the maximum ON resistance for a given
junction temperature, find the normalized ON resistance
factor (NR) from Figure 4. Calculate the new ON
resistance as follows:
(CD00CD, CD01CD) R(ON) = NR • RON @ 25°C
(CD20CD, CD21CD) R(ON) = 0.2 • NR + 0.21
Overload testing to the requirements of MIL-PRF-28750 is
constrained to the limits imposed by the short circuit
protection characteristics as defined in this specification.
System series inductance for “shorted-load” mode of
operation should be 30 µH maximum. Maximum repetition
rate into a shorted load should not exceed 10 Hz.
A status pull up resistor is required for proper operation of
the status output. Determine the current (Iso) required by
the status interface. Calculate the current (Is) through the
status resistor such that the sink current through the
status output is 2 mA. Select the status resistor such that
it does not allow more than 2 mA to flow through the
status output.
RSTATUS
=
VSTATUS - 0.3V
2 mA - Iso
Inductive loads should be diode suppressed. Input
transitions should be ≤ 1 ms duration and the input drive
should be a bounceless contact type.
