NOTES:
1.
Control input is compatible with CMOS or open collector
TTL (with pull up resistor).
2.
The rated input voltage is 5V for all tests unless otherwise
specified.
3.
Transient blocking voltage tests are performed per
MIL-STD-704 (28 Vdc systems).
4.
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.
5.
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
6.
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 H maximum. Maximum repetition
rate into a shorted load should not exceed 10 Hz.
7.
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.

8.
Inductive loads should be diode suppressed. Input
transitions should be ≤ 1 ms duration and the input drive
should be a bounceless contact type.
