1.90mm Height Top View Bi-Color
Hyper Red & Super Pure Green Chip LEDs

This is our 1.90mm Height Top View Bi-Color Hyper Red & Super Pure Green Chip LEDs. The TOP3528 series is available in soft orange, green, blue and yellow. Due to the package design, the LED has wide viewing angle and optimized light coupling by inter reflector. This feature makes the SMT TOP LED ideal for light pipe application. The low current requirement makes this device ideal for portable equipment or any other.

Features:

• P-LCC-4 package.
• White package.
• Optical indicator.
• Colorless clear window.
• Ideal for backlight and light pipe application.
• Inter reflector.
• Wide viewing angle.
• Suitable for vapor-phase reflow, Infrared reflow and wave solder processes.
• Computable with automatic placement equipment.
• Available on tape and reel (8mm Tape).
• The product itself will remain within RoHS compliant Version.

Applications:

• Automotive: Backlight in dashboards and switches.
• Telecommunication: Indicator and backlight in telephone and fax
• Indicator and backlight for audio and video equipment.
• Indicator and backlight in office and family equipment.
• Flat backlight for LCD’s, switches and symbols.
• Light pipe application.
• General use.

Package Dimension:

Notes:

Absolute Maximum Ratings at Ta=25℃

Electrical Optical Characteristics at Ta=25℃

Notes:

• Luminous Intensity Measurement allowance is ± 10%.
• θ_1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
• The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.

Reliability Test Items And Conditions:

The reliability of products shall be satisfied with items listed below:

Confidence level: 90%.

LTPD: 10%.

1) Test Items and Results:

2) Criteria for Judging the Damage:

*) F.V.: First Value.

Reel Dimensions:

Carrier Tape Dimensions:

Loaded quantity 2000PCS per reel.

Please read the following notes before using the datasheets:

1. Over-current-proof

Customer must apply resistors for protection, otherwise slight voltage shift will cause big current change (Burn out will happen).

2. Storage

2.1 Do not open moisture proof bag before the products are ready to use.

2.2 Before opening the package, the LEDs should be kept at 30℃ or less and 90%RH or less.

2.3 The LEDs should be used within a year.

2.4 After opening the package, the LEDs should be kept at 30℃ or less and 70%RH or less.

2.5 The LEDs should be used within 168 hours (7 days) after opening the package.

2.6 If the moisture adsorbent material (silica gel) has fabled away or the LEDs have exceeded the storage time, baking treatment should be performed using the following conditions. Baking treatment: 60±5℃ for 24 hours.

3. Soldering Condition

3.1 Pb-free solder temperature profile.

3.2 Reflow soldering should not be done more than two times.

3.3 When soldering, do not put stress on the LEDs during heating.

3.4 After soldering, do not warp the circuit board.

4. Soldering Iron

Each terminal is to go to the tip of soldering iron temperature less than 260℃ for 5 seconds within once in less than the soldering iron capacity 25W. Leave two seconds and more intervals, and do soldering of each terminal. Be careful because the damage of the product is often started at the time of the hand solder.

5. Repairing

Repair should not be done after the LEDs have been soldered. When repairing is unavoidable, a double-head soldering iron should be used (as below figure). It should be confirmed beforehand whether the characteristics of the LEDs will or will not be damaged by repairing.

6. Caution in ESD

Static Electricity and surge damages the LED. It is recommended to use a wrist band or anti-electrostatic glove when handling the LED. All devices, equipment and machinery mu
