ASMW-LWG0-NxxxE 0.5W 2835 Surface Mount LED Data Sheet Description Features The surface mount LEDs use InGaN chip technology with superior package design to enable them to produce higher light output with better flux performance. They can be driven at high current and are able to dissipate the heat more efficiently resulting in better performance with higher reliability.  Available in CCT 3000K, 4000K, 5000K and 6500K per ANSI  CRI ≥80   High reliability with silicone encapsulation Low package profile and large emitting area for better uniformity in linear lighting Moisture Sensitivity Level 3 These LEDs are able to be operated under a wide range of environmental conditions making ideal for various applications including fluorescent replacement, under cabinet lighting, retail display lighting and panel lights. To facilitate easy pick and place assembly, the LEDs are packed in tape and reel. Every reel is shipped in single flux and color bin, to provide close uniformity.  Applications    For lightings and luminaires Channel letter and advertisement board backlighting Office automations, home appliances, industrial equipment − Front panel backlighting − Push button backlighting − Display backlighting − Scanner lighting CAUTION: This LED is ESD sensitive. Please observe appropriate precautions during handling and processing. Refer to application note AN-1142 for additional details.

Broadcom - 10 - 178.5 60.0 PRODUCT LABEL ASMW-LWG0-NxxxE Data Sheet Precautionary Notes Handling Precautions Soldering The encapsulation material of the LED is made of silicone for better product reliability. Compared to epoxy encapsulant, which is hard and brittle, silicone is softer and flexible. Observe special handling precautions during assembly of silicone encapsulated LED products. Failure to comply might lead to damage and premature failure of the LED. Refer to Broadcom Application Note AN5288, Silicone Encapsulation for LED: Advantages and Handling Precautions, for additional information.      Do not perform reflow soldering more than twice. Observe necessary precautions of handling moisture-sensitive device as stated in the following section. Do not apply any pressure or force on the LED during reflow and after reflow when the LED is still hot. Use reflow soldering to solder the LED. Use hand soldering only for rework if unavoidable, but it must be strictly controlled to following conditions: − Soldering iron tip temperature = 315°C max. − Soldering duration = 3sec max. − Number of cycles = 1 only − Power of soldering iron = 50W max. Do not touch the LED package body with the soldering iron except for the soldering terminals, as it may cause damage to the LED. Confirm beforehand whether the functionality and performance of the LED is affected by soldering with hand soldering.     Figure 16 Recommended Lead-Free Reflow Soldering Profile  TEMPERATURE 10 to 30 SEC. 217°C 200°C 255 – 260°C 3°C/SEC. MAX. 6°C/SEC. MAX. 150°C 3°C/SEC. MAX. Do not poke sharp objects into the silicone encapsulant. Sharp objects, such as tweezers or syringes, might apply excessive force or even pierce through the silicone and induce failures to the LED die or wire bond. Do not touch the silicone encapsulant. Uncontrolled force acting on the silicone encapsulant might result in excessive stress on the wire bond. Hold the LED only by the body. Do not stack assembled PCBs together. Use an appropriate rack to hold the PCBs. Surface of silicone material attracts dust and dirt easier than epoxy due to its surface tackiness. To remove foreign particles on the surface of silicone, use a cotton bud with isopropyl alcohol (IPA). During cleaning, rub the surface gently without putting too much pressure on the silicone. Ultrasonic cleaning is not recommended. For automated pick and place, Broadcom has tested a nozzle size with OD 3.5 mm to work with this LED. However, due to the possibility of variations in other parameters such as pick and place machine maker/model, and other settings of the machine, verify that the selected nozzle will not cause damage to the LED.
