BNS-OD-C131/A4
Part No. : LTL-1CHE-041A
Suggestions to prevent ESD damage:
ESD-damaged Leeds will exhibit abnormal characteristics such as high reverse leakage current, low
forward voltage, or “no light up” at low currents. To verify for ESD damage, check for “light up” and
Vf of the suspect LEDs at low currents.
Static Electricity or power surge will damage the LED.
The Vf of “good” LEDs should be >2.0V@0.1mA for InGaN product and >1.4V@0.1mA for AlInGaP product.
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.
An LED is a current-operated device. In order to ensure intensity uniformity on multiple LEDs
(A) Recommended circuit
(B) The brightness of each LED might appear different due to the differences in the I-V characteristics
Use 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 LEDs
plastic lens as a result of friction between LEDs during storage and handing
of those LEDs
