5. Drive Method
6. ESD (Electrostatic Discharge)
Static Electricity or power surge will damage the LED.
Suggestions to prevent ESD damage:
(A) Recommended circuit.
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs connected
in parallel in an application, it is recommended that a current limiting resistor be incorporated in the
drive circuit, in series with each LED as shown in Circuit A below.
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics
Use of a conductive wrist band or anti-electrostatic glove when handling these LEDs.
All devices, equipment, and machinery must be properly grounded.
Work tables, storage racks, etc. should be properly grounded.
Use ion blower to neutralize the static charge which might have built up on surface of the LED’s
plastic lens as a result of friction between LEDs during storage and handling.
ESD-damaged LEDs will exhibit abnormal characteristics such as high reverse leakage current, low forward
To verify for ESD damage, check for “ lightup ” and Vf of the suspect LEDs at low currents.
The Vf of “ good ” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP
