DESCRIPTION:
The MHS series are Solid State Relays, where the input and output circuitry are isolated from each other. The series
consists of both singles and duals, and provides both the normally open (N.O.) function as well as the normally closed
(N.C.) function. Packaging one of each (a N.O. and a N.C.) in a package creates the SPDT function.

Internal switch is rated for > 1000 Volts breakdown. Consult factory for use at Voltages greater than 250 Volts.
Current handling capability depends upon allowable Tcase and allowable T
j
. See Figure 1.
Microsemi does not at this time have a MIL-PRF-38534 qualified radiation hardness assurance program.
Not tested.
Because of the relatively slow switching times involved in power SSRs, it is important to stay within the allowances of
the device performance curves.
