Part Number1 Peak Wavelength Optical Output at 100 mA2 Min MaxMin OPTAN-WSK-SMD 260 nm 275 nm 2 mW Notes: 1. LEDs are produced with semiconductor technology that is subject to process variation, yielding a range of flux performance that is approximately Gaussian in nature. To provide customers with fine granularity within the overall flux distribution, Crystal IS separates LEDs into optical power bins. WWW.CISUVC.COM 2. Output power is measured using a 100 mA current pulse of < 1s duration at an ambient temperature of 25 °C ± 5 °C with the diode inserted into an integrating sphere.

Please refer to the Crystal IS thermal management note AN007 for heat sink recommendations. Circuits should be designed for constant current. 1. The tip of the soldering iron should never touch the lens. 2. Hand soldering is recommended: 300 °C maximum (temperature of soldering iron tip), 3 seconds maximum (one time only). 3. Recommended soldering pattern is illustrated in Figure 1. In addition, ensure that the central copper slug is thermally connected to the board with thermal paste or grease. A heat sink may be required to maintain the LED at the desired case temperature. Please refer to the Crystal IS thermal management note AN007 for heat sink recommendations.

When handling, proper ESD protection is required, including: > Eliminating static charge > Using grounded wriststrap, ESD footwear, clothes, and floors > Grounded workstation and tools Eye Safety Guidelines During operation, the LED emits high intensity ultraviolet (UV) light, which is harmful to skin and eyes. UV light is hazardous to skin and may cause cancer. Avoid exposure to UV light when LED is operational. Precautions must be taken to avoid looking directly at the UV light without the use of UV light protective glasses. Do not look directly at the front of the LED or at the LED’s lens when LED is operational. Attach the following warning labels on products/systems that use UV LEDs. RoHS Compliance The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or otherwise 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 2002/95/EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as amended through April 21, 2006.
