Solid State Relay
OCMOS FET
PS7241-2B
8-PIN SOP, 400 V BREAK DOWN VOLTAGE NORMALLY CLOSE TYPE
2-ch Optical Coupled MOS FET
DESCRIPTION
The PS7241-2B 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 their low offset and high linearity.
FEATURES
2 channel type (1 b + 1 b output)
Low LED operating current (I
F
= 2 mA)
Designed for AC/DC switching line changer
Small and thin package (8-pin SOP, Height = 2.1 mm)
Low offset voltage
Ordering number of taping product: PS7241-2B-F3, F4
UL approved: File No. E72422 (S)
BSI approved: No. 8241/8242
CSA approved: No. CA 101391

Subject: Compliance with EU Directives
CEL certifies, to its knowledge, that semiconductor and laser products detailed below are compliant
with the requirements of European Union (EU) Directive 2002/95/EC Restriction on Use of Hazardous
Substances in electrical and electronic equipment (RoHS) and the requirements of EU Directive
2003/11/EC Restriction on Penta and Octa BDE.
CEL Pb-free products have the same base part number with a suffix added. The suffix A indicates
that the device is Pb-free. The AZ suffix is used to designate devices containing Pb which are
exempted from the requirement of RoHS directive (*). In all cases the devices have Pb-free terminals.
All devices with these suffixes meet the requirements of the RoHS directive.
This status is based on CEL's understanding of the EU Directives and knowledge of the materials that
go into its products as of the date of disclosure of this information.
