MS14 Series Military Solid State Relay
With Bi-Directional Output to 240mA & 400V
Product Facts
■ 1000V optical isolation
protects control and driver
circuitry from load
transients.
■ Buffered/current limited
input for direct drive from
CMOS or TTL logic.
■ Power MOSFET output chips
for low voltage drop and
MS14 series subminiature
SSRs employ state of the art
photo-voltaic optical isolation
providing 1000Vrms
input/output isolation and back
to back power MOSFET output
chips for ultra-reliable high
speed switching of AC, DC and
bipolar DC loads up to 240mA
at load voltages up to 400Vdc.
The input is current regulated
and buffered to minimize power
dissipation and permit driving
the relay direct from CMOS or
TTL. The relay is packaged in a
custom hermetically sealed
low-profile .100 grid package
which conserves space for high
density PC board circuitry.
virtually no offset voltage.
■ 90 & 240mA output current
options.
■ 100 & 400V output voltage
options.
■ Subminiature hermetically
sealed .100 grid package.
■ Screened per “Y” level of
MIL-PRF-28750D or CII “W”
level.
