HIGH COLLECTOR TO EMITTER VOLTATGE
HIGH ISOLATION VOLTAGE
MULTI PHOTOCOUPLER SERIES
−NEPOC Series−
DESCRIPTION
The PS2532-1, -2, -4 and PS2532L-1, -2, -4 are optically coupled isolators containing a GaAs light emitting diode
and an NPN silicon darlington connected phototransistor.
The PS2532-1, -2, -4 are in a plastic DIP (Dual In-line Package) and the PS2532L-1, -2, -4 are lead bending type
(Gull-wing) for surface mount.

• Number of times
One (Allowed to be dipped in solder including plastic mold portion.)
• Flux
Rosin flux containing small amount of chlorine (The flux with a maximum chlorine
content of 0.2 Wt% is recommended.)
(3) Cautions
• Fluxes
Avoid removing the residual flux with freon-based and chlorine-based cleaning solvent.
2. Cautions regarding noise
Be aware that when voltage is applied suddenly between the photocoupler’s input and output or between
collector-emitters at startup, the output side may enter the on state, even if the voltage is within the absolute
maximum ratings.

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.
