(Gull-wing) for surface mount.
FEATURES
• AC input response
• High isolation voltage (BV = 5 000 Vr.m.s.)
• High collector to emitter voltage (VCEO = 80 V)
• High-speed switching (tr = 3
µ
s TYP., tf = 5

• Ordering number of tape product: PS2505L-1-E3, E4, F3, F4, PS2505L-2-E3, E4
• Safety standards
• UL approved: File No. E72422 (S)
APPLICATIONS
• Power supply
• Telephone/FAX.
• FA/OA equipment
• Programmable logic controller

NOTES ON HANDLING
1. Recommended soldering conditions
(1) Infrared reflow soldering
• Peak reflow temperature 235 °C or below (package surface temperature)
• Time of temperature higher than 210 °C 30 seconds or less
• Number of reflows Three
• Flux Rosin flux containing small amount of chlorine (The flux with a
maximum chlorine content of 0.2 Wt % is recommended.)
60 to 120 s
(preheating)
210 ˚C
100 to 160 ˚C
Package Surface Temperature T (˚C)
Time (s)
(heating)
to 10 s
to 30 s
235 ˚C (peak temperature)
Recommended Temperature Profile of Infrared Reflow
(2) Dip soldering
• Temperature 260 °C or below (molten solder temperature)
• Time 10 seconds or less
• 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
corrector-emitters at startup, the output side may enter the on state, even if the voltage is within the absolute
maximum ratings .

Descriptions of circuits, software and other related information in this document are provided for illustrative
purposes in semiconductor product operation and application examples. The incorporation of these
circuits, software and information in the design of customer's equipment shall be done under the full
responsibility of customer. NEC assumes no responsibility for any losses incurred by customers or third
parties arising from the use of these circuits, software and information.
While NEC endeavours to enhance the quality, reliability and safety of NEC semiconductor products, customers
agree and acknowledge that the possibility of defects thereof cannot be eliminated entirely. To minimize
risks of damage to property or injury (including death) to persons arising from defects in NEC
semiconductor products, customers must incorporate sufficient safety measures in their design, such as
redundancy, fire-containment, and anti-failure features.
NEC semiconductor products are classified into the following three quality grades:
"Standard", "Special" and "Specific". The "Specific" quality grade applies only to semiconductor products
developed based on a customer-designated "quality assurance program" for a specific application. The
recommended applications of a semiconductor product depend on its quality grade, as indicated below.
Customers must check the quality grade of each semiconductor product before using it in a particular
application.
"Standard": Computers, office equipment, communications equipment, test and measurement equipment, audio
and visual equipment, home electronic appliances, machine tools, personal electronic equipment
and industrial robots
"Special": Transportation equipment (automobiles, trains, ships, etc.), traffic control systems, anti-disaster
systems, anti-crime systems, safety equipment and medical equipment (not specifically designed
for life support)
"Specific": Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life
support systems and medical equipment for life support, etc.
The quality grade of NEC semiconductor products is "Standard" unless otherwise expressly specified in NEC's
data sheets or data books, etc. If customers wish to use NEC semiconductor products in applications not
intended by NEC, they must contact an NEC sales representative in advance to determine NEC's willingness
to support a given application.
(Note)
(1) "NEC" as used in this statement means NEC Corporation and also includes its majority-owned subsidiaries.
(2) "NEC semiconductor products" means any semiconductor product developed or manufactured by or for
NEC (as defined above).
