FEATURES
• High Voltage
• TTL and CMOS compatible control
• Low ON resistance power SiC MOSFET output
• Fast switching speed
• Meets 270 Vdc system requirements of
MIL-STD-704
• Optical isolation
• Low profile hermetic package
• Built and tested to the requirements of
MIL-PRF-28750
DESCRIPTION
The Series LD00KM 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
fl
oating power FET
output technology. This allows the load to be con-
nected 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.

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. Inductive loads should be diode suppressed. Input transitions should be
≤1
ms duration and the input drive should be a bounce-
less contact type.
4. Contact factory for higher voltage relays.
