DESCRIPTION
The Series KD and LD solid-state relays
are screened utilizing MIL-PRF-28750
test methods and are packaged in low
profile hermetically sealed cases. These
relays are constructed with state-of-the-
art solid state techniques and feature
fully floating power FET output
technology. This allows the load to be
connected to either output terminal and
provides a low ON resistance. The input
(control) and output are optically isolated
to protect input logic circuits from output
transients. Available options include
short circuit and current overload
protection, which provides complete
protection for both the relay and 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. The second option
is a status output line. Switch status
returns the true status of the output
switch and is optically isolated from the
load. It provides status indication
independent of the control circuit of the
relay. The status line provides a logic 0
(low) when the relay output is off with
load voltage and continuity present, and
a logic 1 (high) when the output is on.

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 8.
2. The rated input voltage is 5V for all tests unless otherwise specified.
3. 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:
R(ON) = NR • RON @ 25°C
(KD00CK, LD00CM, KD02CK, LD02CM)
R(ON) = NR(RON @ +25°C ) + .025 ohm
(KD20CK, LD20CM, KD22CK, LD22CM)
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 50 µH.
Maximum repetition rate into a shorted load should not exceed 10 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 is 0.6 mA. Select the
status resistor such that it does not allow more than 0.6 mA to flow through the status
output.
RSTATUS =
V - 0.4V

6. Inductive loads should be diode suppressed. Input transitions should be 1 ms duration
and the input drive should be a bounceless contact type.
