DESCRIPTION
INPUT (CONTROL) SPECIFICATION
When used in 2 terminal configuration
(TTL or direct control) (See Fig. 1)
Min
Typ
The KD and LD series solid state
relays are screened utilizing MIL-R28750 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. These
options are available either together
or separately as standard features.

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 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
R(ON) =
D

(KD00CK, LD00CM, KD02CK, LD02CM)
NR(RON @ +25°C ) + .025 ohm
(KD20CK, LD20CM, KD22CK, LD22CM)
4. Overload testing to the requirements of MIL-R-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.
VSTATUS - 0.4V
RSTATUS =
Iso
6. Inductive loads should be diode suppressed. Input transitions should be ≤ 1 ms
duration and the input drive should be a bounceless contact type.
