2) Tube
(1) De vices are pac kaged in a tube so pin
No. 1 is on the stopper B side.
Observe correct orientation when mount-
ing them on PC boards.
(SOP type)
2) Storage
PhotoMOS relays implemented in SO
packages are sensitive to moisture and
come in sealed moisture-proof packages.
Observe the following cautions on stor-
age.
• After the moisture-proof package is un-
sealed, take the de vices out of stor age as
soon as possible (within 1 month at the
most).
• If the de vices are to be left in storage for
a considerable period after the moisture-
proof package has been unsealed, it is
recommended to keep them in another
moisture-proof bag containing silica gel
(within 3 months at the most).
10. Transportation and storage
1) Extreme vibration during transport will
warp the lead or damage the relay. Han-
dle the outer and inner boxes with care.
2) Storage under extreme conditions will
cause soldering degradation, external ap-
pearance def ects, and deterioration of the
characteristics. The following stor age con-
ditions are recommended:
• Temperature: 0 to 45°C 32 to 113°F
• Humidity: Less than 70% R.H.
• Atomosphere: No harmful gasses such
as sulfurous acid gas, minimal dust.
11. Applying stress that exceeds the
absolute maximum rating
If the voltage or current value for any of
the terminals exceeds the absolute maxi-
mum rating, internal elements will deterio-
rate because of the excessive voltage or
current. In extreme cases, wiring may
melt, or silicon P/N junctions may be de-
stroyed.
As a result, the design should ensure that
the absolute maximum ratings will never
be exceeded, even momentarily.
(Use at 15 VDC or lower and 9 VAC or
lower is recommended.)
12. Deterioration and destruction
caused by discharge of static
electricity
This phenomenon is generally called stat-
ic electricity destruction, and occurs when
static electricity generated by various fac-
tors is discharged while the relay termi-
nals are in contact, producing internal
destruction of the element.
To pre vent problems from static electricity,
the following precautions and measures
should be taken when using your device.
1) Employees handling relays should
wear anti-static clothing and should be
grounded through protectiv e resistance of
500 k
Ω
to 1 M
Ω
.
2) A conductive metal sheet should be
placed over the work table. Measuring in-
struments and jigs should be grounded.
3) When using soldering irons, either use
irons with low leakage current, or ground
the tip of the soldering iron. (Use of low-
voltage soldering irons is also recom-
mended.)
4) De vices and equipment used in assem-
bly should also be grounded.
5) When packing printed circuit boards
and equipment, avoid using high-polymer
materials such as foam styrene, plastic,
and other materials which carry an elec-
trostatic charge.
6) When storing or transporting relays, the
environment should not be conducive to
generating static electricity (for instance,
the humidity should be between 45 and
60%), and relays should be protected us-
ing conductive packing materials.
