(3) Recommended circuit
(4) Static Electricity
· In designing a circuit, the current through each LED must not exceed the absolute maximum rating
· This product should be operated in forward bias. A driving circuit must be designed so that the product
· Static electricity or surge voltage damages the LEDs.
· All devices, equipment and machinery must be properly grounded. It is recommended that precautions
· When inspecting the final products in which LEDs were assembled, it is recommended to check
· Damaged LEDs will show some unusual characteristics such as the forward voltage becomes lower,
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 (V
worst case, some LED may be subjected to stresses in excess of the absolute maximum rating.
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.
It is recommended that a wrist band or an anti-electrostatic glove be used when handling the LEDs.
