Cree® XLamp® ML-C LEDs

PRODUCT DESCRIPTION

The Cree XLamp ML-C LED brings

lighting-class reliability and

performance to 1/3-watt LEDs.

The XLamp ML-C expands Cree’s

lighting-class leadership to LED

bulbs and linear and distributed

lighting applications. With XLamp

lighting-class reliability, a wide

viewing angle, uniform light

output, and industry-leading

chromaticity binning in a 3.5-mm

X 3.5-mm package, the XLamp

ML-C LED continues Cree’s history

of segment-focused product

innovation in LEDs for lighting

applications.

The XLamp ML-C LED brings

high performance and a smooth

look to a wide range of lighting

applications, including linear

lighting, uorescent retrots and

retail-display lighting.

FEATURES

THERMAL DESIGN - ML-C PARALLEL WHITE

The maximum forward current is determined by the thermal resistance between the LED junction and ambient. It is

crucial for the end product to be designed in a manner that minimizes the thermal resistance from the solder point to

ambient in order to optimize lamp life and optical characteristics.

REFLOW SOLDERING CHARACTERISTICS

In testing, Cree has found XLamp ML-C LEDs to be compatible with JEDEC J-STD-020C, using the parameters listed

below. As a general guideline, Cree recommends that users follow the recommended soldering prole provided by the

manufacturer of solder paste used.

Note that this general guideline may not apply to all PCB designs and congurations of reow soldering equipment.

Prole Feature Lead-Based Solder Lead-Free Solder

Average Ramp-Up Rate (Tsmax to Tp) 3 °C/second max. 3 °C/second max.

Preheat: Temperature Min (Tsmin) 100 °C 150 °C

Preheat: Temperature Max (Tsmax) 150 °C 200 °C

Preheat: Time (tsmin to tsmax) 60-120 seconds 60-180 seconds

Time Maintained Above: Temperature (TL) 183 °C 217 °C

Time Maintained Above: Time (tL) 60-150 seconds 60-150 seconds

Peak/Classication Temperature (Tp) 215 °C 260 °C

Time Within 5 °C of Actual Peak Temperature (tp) 10-30 seconds 20-40 seconds

Ramp-Down Rate 6 °C/second max. 6 °C/second max.

Time 25 °C to Peak Temperature 6 minutes max. 8 minutes max.

Note: All temperatures refer to topside of the package, measured on the package body surface.

Note: While the high reow temperatures (above) have been approved, Cree’s best practice guideline for reow is to use

as low a temperature as possible during the reow soldering process for these LEDs.

NOTES

Lumen Maintenance Projections

Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED

lumen maintenance. For information on the specic LM-80 data sets available for this LED, refer to the public LM-80

results document at www.cree.com/xlamp_app_notes/LM80_results.

Please read the XLamp Long-Term Lumen Maintenance application note at www.cree.com/xlamp_app_notes/lumen_

maintenance for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal

Management application note at www.cree.com/xlamp_app_notes/thermal_management for details on how thermal

design, ambient temperature, and drive current affect the LED junction temperature.

Moisture Sensitivity

XLamp ML-C LEDs are shipped in sealed, moisture-barrier

bags (MBB) designed for long shelf life. If XLamp ML-C LEDs

are exposed to moist environments after opening the MBB

packaging but before soldering, damage to the LED may occur

during the soldering operation. The derating table at right

denes the maximum exposure time (in days) for an XLamp

ML-C LED in the listed humidity and temperature conditions. LEDs with exposure time longer than the time specied

below must be baked according to the baking conditions listed below.

Cree recommends keeping XLamp LEDs in their sealed moisture-barrier packaging until immediately prior to use. Cree

also recommends returning any unused LEDs to the resealable moisture-barrier bag and closing the bag immediately

after use.

Baking Conditions

It is not necessary to bake all XLamp ML-C LEDs. Only the LEDs that meet all of the following criteria must be baked:

1. LEDs that have been removed from the original MBB packaging.

2. LEDs that have been exposed to a humid environment longer than listed in the Moisture Sensitivity section above.

3. LEDs that have not been soldered.

LEDs should be baked at 70 ºC for 24 hours. LEDs may be baked on the original reels. Remove LEDs from MBB packaging

before baking. Do not bake parts at temperatures higher than 70 ºC. This baking operation resets the exposure time as

dened in the Moisture Sensitivity section above.

trademarks of Cree, Inc.

XLamp mL-C LEDs

Storage Conditions

XLamp ML-C LEDs that have been removed from the original MBB packaging but not soldered should be stored in one

of the following ways:

• Store the parts in a rigid metal container with a tight-tting lid. Verify that the storage temperature is <30 °C, and

place fresh desiccant and an RH indicator in the container to verify that the RH is no greater than 60%.

• Store the parts in a dry, nitrogen-purged cabinet or container that actively maintains the temperature at <30° and

the RH at no greater than 60%.

• For short-term store only: LEDs can be resealed in the original MBB bag soon after opening. Fresh desiccant may be

needed. Use the included humidity indicator card to verify <60% RH.

If an environment of <60% RH is not available for storage, XLamp ML-C LEDs should be baked (described above) before

reow soldering.

RoHS Compliance

The levels of RoHS restricted materials in this product are below the maximum concentration values (also referred to

as the threshold limits) permitted for such substances, or are used in an exempted application, in accordance with EU

Directive 2011/65/EC (RoHS2), as implemented January 2, 2013. RoHS Declarations for this product can be obtained

from your Cree representative or from the Product Documentation sections of www.cree.com.

Vision Advisory Claim

WARNING. Do not look at exposed LED lamps in operation. Eye injury can result. For more information about LEDs and

eye safety, please refer to the Cree LED Eye Safety Application Note (www.cree.com/xlamp_app_notes/led_eye_safety).
