PRELIMINARY DATA SHEET
OCMOS FET
PS7241S-1A
CURRENT LIMIT TYPE
4-PIN SOP 400 V OCMOS FET
(1-ch OCMOS FET)
DESCRIPTION
The PS7241S-1A is a solid state relay containing GaAs LEDs on the light emitting side (input side) and MOS FETs
including current control circuit on the output side. Current control circuit of OCMOS FET protects this device from
thermal breakdown and output circuit.
It is suitable for analog signal control because of its low offset and high linearity.
FEATURES
• Shut down type circuit
