Solid State Relay
OCMOS FET
PS7241-1B
4-PIN SOP 400 V BREAK DOWN VOLTAGE NORMALLY CLOSE TYPE
1-ch Optical Coupled MOS FET
DESCRIPTION
The PS7241-1B is a solid state relay containing GaAs LEDs on the light emitting side (input side) and normally
close (N.C.) contact MOS FETs on the output side.
It is suitable for analog signal control because of its low offset and high linearity.
