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 µH 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.

RSTATUS

=

V - 0.3V

STATUS

2 mA - Iso

8. Inductive loads should be diode suppressed. Input

transitions should be ≤ 1 ms duration and the input drive

should be a bounceless contact type.
