CAUTION FOR CLASS 1 ESD ( MACHINE MODE )
Gallium Nitride (GaN) based light emitting diodes (LEDs) are extremely sensitive to electrostatic
discharge (ESD). Users are strongly recommended to take necessary meter to test the static
and avoid ESD when handing these products.
Bright View's BA, GN, WI series products are GaN based materials and are classified as
"Class 1",( ESD endurance 50V or lower ), any manufacturing site or workstation where
GaN devices are handled should be rated and controlled at 50V or below.
Proper grounding of products or machines ( via 1MΩ ), using static dissipative mats, static
dissipative containers, static dissipative working uniferms and shoes are considered to be
effective against ESD.
An ionizer is recommended in the facility or environment where ESD may be generated
easily, and soldering iron with a grounded tip is also recommended.
To install a protection device in the LED circuit to ensure the surge current and voltage not
exceeding the max rating during on/off swithing.
When inspecting the final products in which LEDs are assembled, it is recommended to
check whether the assembled LEDs are damaged by ESD or not. It is simple to find
damaged LEDs by light-on or a VF test at lower current (below 1mA is recommended).
ESD damaged LEDs will show some unusual characteristics such as the remarkable
increasing of leak current, the forward voltage become lower, or the LEDs do not light on
at the low current.
