The KD44CF solid-state relay is screened
utilizing the test methods of MIL-PRF-28750
and is packaged in a low-profile hermetically
sealed case. These relays are constructed
using state-of-the-art hybrid technology.
They feature fully floating power FET
outputs that allow the load to be connected
to either output terminal and provides a
low ON resistance. The input (control) and
the output are optically isolated to protect
input logic circuits from output transients.
The short-circuit/overload protection is
temperature compensated, and has a flat trip
characteristic over the operating temperature
range. These relays will not be damaged by
a continuous short circuit on the load, or by
being turned on into a short circuit. A trip
status indicator turns on when an overcurrent
condition has occured, and the short-circuit
protection has been activated. Cycling the
control voltage resets the output switch and
trip status indicator.

NOTES:
1. Control input is compatible with CMOS or open collector TTL (with pull up resistor). For bias voltages above 6V, a series resistor is
required. Use the standard resistor value equal to or less than the value found in Figure 4.
2. The rated input voltage is 5V for all tests unless otherwise specified.
3. To calculate the maximum ON resistance for a given ꢀunction temperature, find the normalized ON resistance factor (NR) from
Figure 5. Calculate the new ON resistance as follows:
R(ON) = NR • RON @ 25°C + 0.15
4. 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 1 Hz.
5. 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 does not
exceed 15 mA.
VSTATUS - 0.4V
RSTATUS
=
IS
6. Inductive loads should be diode suppressed. Input transitions should be ≤1 ms duration and the input drive should be a
bounceless contact type.
7. Input transitions should be ≤ 1 msec.
