7.CAUTIONS
The LEDs are devices which are materialized by combining Blue LEDs and special phosphors.
Consequently, the color of the LEDs is changed a little by an operating current.
Care should be taken after due consideration when using LEDs.
(1) Storage
· Storage Conditions
Before opening the package :
The LEDs should be kept at 30°C or less and 90%RH or less. The LEDs should be used within a
year.
When storing the LEDs, moisture proof packaging with absorbent material (silica gel)
is recommended.
After opening the package :
The LEDs should be kept at 30°C or less and 70%RH or less.
The LEDs should be soldered
within 168 hours (7days) after opening the package.
If unused LEDs remain, they should be
stored in moisture proof packages, such as sealed containers with packages of moisture absorbent
material (silica gel). It is also recommended to return the LEDs to the original moisture proof bag
and to reseal the moisture proof bag again.
· If the moisture absorbent material (silica gel) has faded away or the LEDs have exceeded the storage
time, baking treatment should be performed using the following conditions.
Baking treatment : more than 24 hours at 85°C
· Nichia LED leadframes are silver plated copper alloy. The silver surface may be affected by
environments which contain corrosive substances. Please avoid conditions which may cause the LED
to corrode, tarnish or discolor. This corrosion or discoloration may cause difficulty during soldering
operations. It is recommended that the LEDs be used as soon as possible.
· Please avoid rapid transitions in ambient temperature, especially, in high humidity environments where
condensation can occur.
(2) Recommended circuit
· In designing a circuit, the current through each LED must not exceed the absolute maximum rating
specified for each LED. It is recommended to use Circuit B which regulates the current flowing
through each LED. In the meanwhile, when driving LEDs with a constant voltage in Circuit A, the
current through the LEDs may vary due to the variation in forward voltage (VF) of the LEDs. In the
worst case, some LED may be subjected to stresses in excess of the absolute maximum rating.
(B)
(A)
...
...
· This product should be operated in forward bias. A driving circuit must be designed so that the product
is not subjected to either forward or reverse voltage while it is off. In particular, if a reverse voltage is
continuously applied to the product, such operation can cause migration resulting in LED damage.
-4-
Nichia STS-DA1-0230C
<Cat.No.090428>
(3) Static Electricity
· Static electricity or surge voltage damages the LEDs.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that precautions
be taken against surge voltage to the equipment that mounts the LEDs.
· When inspecting the final products in which LEDs were assembled, it is recommended to check
whether the assembled LEDs are damaged by static electricity or not.
It is easy to find
static-damaged LEDs by a light-on test or a VF test at a lower current (below 1mA is recommended).
· Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,
or the LEDs do not light at the low current.
Criteria : (VF > 2.0V at IF=0.5mA)

Nichia STS-DA1-0230C
<Cat.No.090428>
(4) Soldering Conditions
· Nichia LEDs uses a copper alloy lead frame which provides a high thermal conductivity.
Thermal
stress such as soldering heat may reduce the reliability of the product; particular caution should be
used to avoid damage prior to and during soldering.
The recommended soldering conditions are
listed in the following table.
· Solder the LED no closer than 1.6mm from the base of the stopper.
· The mechanical stress by clinching will cause degradation of the reliability on the LEDs. It is
important to minimize the mechanical stress on the LEDs.
It should be confirmed beforehand
that it will not cause any problem when using it.
· Recommended soldering conditions
Dip Soldering
Hand Soldering
Pre-Heat
120°C Max.
Temperature
350°C Max.
Pre-Heat Time
60 seconds Max.
Soldering Time
3 seconds Max.
Solder Bath
260°C Max.
Position
No closer than 1.6 mm from the
base of the stopper.
Temperature
Dipping Time
5 seconds Max.
Dipping Position
No lower than 1.6 mm from the
base of the stopper.
· Although the recommended soldering conditions are specified in the above table, dip or hand
soldering at the lowest possible temperature is desirable for the LEDs.
· A rapid-rate process is not recommended for cooling the LEDs down from the peak temperature.
· Dip soldering should not be done more than one time.
· Hand soldering should not be done more than one time.
· Do not apply any stress to the lead particularly when heated.
· The LEDs must not be repositioned after soldering.
· After soldering the LEDs, the epoxy bulb should be protected from mechanical shock or vibration until
the LEDs return to room temperature.
· Direct soldering onto a PC board should be avoided.
Mechanical stress to the resin may be caused
from warping of the PC board or from the clinching and cutting of the leadframes.
When it is
absolutely necessary, the LEDs may be mounted in this fashion but the customer will assume
responsibility for any problems.
Direct soldering should only be done after testing has confirmed that
no damage, such as wire bond failure or resin deterioration, will occur.
Nichia’s LEDs should not be
soldered directly to double sided PC boards because the heat will deteriorate the epoxy resin.
· When it is necessary to clamp the LEDs to prevent soldering failure, it is important to minimize
the mechanical stress on the LEDs.
· Cut the LED leadframes at room temperature.
Cutting the leadframes at high temperatures may
cause failure of the LEDs.
(5) Cleaning
· It is recommended that isopropyl alcohol be used as a solvent for cleaning the LEDs. When using
other solvents, it should be confirmed beforehand whether the solvents will dissolve the resin or not.
Freon solvents should not be used to clean the LEDs because of worldwide regulations.
· Do not clean the LEDs by the ultrasonic. When it is absolutely necessary, the influence of ultrasonic
cleaning on the LEDs depends on factors such as ultrasonic power and the assembled condition.
Before cleaning, a pre-test should be done to confirm whether any damage to the LEDs will occur.

<Cat.No.090428>
(6) Heat Generation
· Thermal design of the end product is of paramount importance.
Please consider the heat generation
of the LED when making the system design. The coefficient of temperature increase per input
electric power is affected by the thermal resistance of the circuit board and density of LED placement
on the board, as well as other components. It is necessary to avoid intense heat generation and operate
within the maximum ratings given in this specification.
· Please determine the operating current with consideration of the ambient temperature local to the LED
and refer to the plot of Ambient temperature vs. Allowable Forward Current on CHARACTERISTICS
in this specifications. Please also take measures to remove heat from the area near the LED to improve
the operational characteristics of the LED.
· The equation 1 indicates correlation between Tj and Ta, and the equation 2 indicates correlation
between Tj and Ts1.
Tj=Ta + Rja W
1
Tj=Ts1 + Rjs1 W
2
Tj = Dice Temperature : °C, Ta = Ambient Temperature : °C,
Ts1 = Solder Temperature (Cathode Side) : °C,
Rja = Heat resistance from Dice to Ambient temperature : °C /W,
Rjs1 = Heat resistance from Dice to Ts1 measuring point : °C /W,
W = Inputting Power (IF VF) : W
(7) Safety Guideline for Human Eyes
· The International Electrical Commission (IEC) published in 2006 IEC 62471:2006 Photobiological
safety of lamps and lamp systems which includes LEDs within its scope. Meanwhile LEDs were
removed from the scope of the IEC 60825-1:2007 laser safety standard, the 2001 edition of which
included LED sources within its scope. However, keep in mind that some countries and regions have
adopted standards based on the IEC laser safety standard IEC 60825-1:2001 which includes LEDs
within its scope.
Following IEC 62471:2006, most of Nichia LEDs can be classified as belonging to either Exempt
Group or Risk Group 1. Optical characteristics of a LED such as output power, spectrum and light
distribution are factors that affect the risk group determination of the LED. Especially a high-power
LED, that emits light containing blue wavelengths, may be in Risk Group 2.
Great care should be taken when viewing directly the LED driven at high current or the LED with
optical instruments, which may greatly increase the hazard to your eyes.
