• High isolation voltage (BV = 5 000 Vr.m.s.)
• High current transfer ratio (CTR = 2 000 % TYP.)
• High-speed switching (tr, tf = 100
µ
s TYP.)
• Ordering number of tape product: PS2506L-1-E3, E4, F3, F4, PS2506L-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 .

The information in this document is current as of March, 2001. The information is subject to change
without notice. For actual design-in, refer to the latest publications of NEC's data sheets or data
books, etc., for the most up-to-date specifications of NEC semiconductor products. Not all products
and/or types are available in every country. Please check with an NEC sales representative for
availability and additional information.
No part of this document may be copied or reproduced in any form or by any means without prior
written consent of NEC. NEC assumes no responsibility for any errors that may appear in this document.
NEC does not assume any liability for infringement of patents, copyrights or other intellectual property rights of
third parties by or arising from the use of NEC semiconductor products listed in this document or any other
liability arising from the use of such products. No license, express, implied or otherwise, is granted under any
patents, copyrights or other intellectual property rights of NEC or others.
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)
