(6) 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 measures 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 leak current remarkably increases,
the forward voltage becomes lower, or the LEDs do not light at the low current.
Criteria: (VF > 2.0V at IF=0.5mA)

Care must be taken to ensure that the reverse voltage will not exceed the absolute maximum rating
when using the LEDs with matrix drive.
The LED light output is strong enough to injure human eyes. Precautions must be taken to prevent
looking directly at the LEDs with unaided eyes for more than a few seconds.
The LEDs described in this brochure are intended to be used for ordinary electronic equipment (such
as office equipment, communications equipment, measurement instruments and household appliances).
Consult Gilway’s sales staff in advance for information on the applications in which exceptional
quality and reliability are required, particularly when the failure or malfunction of the LEDs may
directly jeopardize life or health (such as airplanes, aerospace, submersible repeaters, nuclear reactor
control systems, automobiles, traffic control equipment, life support systems and safety devices).
User shall not reverse engineer by disassembling or analysis of the LEDs without having prior written
consent from Gilway. When defective LEDs are found, the User shall inform Gilway directly before
disassembling or analysis.
