DESCRIPTION
The PS2561A-1 is an optically coupled isolator containing a GaAs light emitting diode and an NPN silicon
phototransistor to realize an excellent cost performance.
The PS2561A-1 is in a plastic DIP (Du al In-line P ackage) and the PS256 1AL-1 is le ad bending t ype (Gull- wing) for
surface mount.
The PS2561AL1-1 is lead bending L1 type and the PS2561AL2-1 is lead bending L2 type (Gull-wing).

(2) Wave soldering
• Temperature 260°C or below (molten solder temperature)
• Time 10 seconds or less
• Preheating conditions 120°C or below (package sur f ace temperature)
• Number of times One (Allowed to be di pped in solder including plastic mo ld portion.)
• Flux Rosin flux containing sma ll amount of chlorine (The flux with a maximum chlorine
content of 0.2 Wt% is recommended.)
(3) Soldering by soldering iron
• Peak temperature (lead part temperature) 350°C or below
• Time (each pins) 3 seconds or less
• Flux Rosin flux containing sma ll amount of chlorine (The flux with a
maximum chlorine content of 0.2 Wt% is recommended.)
(a) Soldering of leads should be made at the point 1.5 to 2.0 mm from the root of the lead.
(b) Please be sure that the temperature of the package would not be heated over 100°C.

PS2561A-1,PS2561AL-1,PS2561AL1-1,PS2561AL2-1
(4) Cautions
• Fluxes
Avoid removing the residual flux with freon- based and chlorine-based cleanin g 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 transistor may enter the on state, even if the voltage is within the absolute
maximum ratings.
USAGE CAUTIONS
1. Protect against static electricity when handlin g.
2. Avoid storage at a high temperature and high humidity.

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.
