The SML-LX0603SIW-TR is a surface-mount AllnGaP red LED designed for visual indication in a compact 0603 package. It emits light at a peak wavelength of 636 nm with a typical axial intensity of 60 mcd when driven at a 20 mA forward current. The device features a wide 140-degree viewing angle due to its diffused lens and operates with a typical forward voltage of 2.0V. It is rated for an operating temperature range of -25°C to +85°C and has a maximum power dissipation of 50 mW. Its small size and surface-mount design make it suitable for applications like backlighting and status indicators where board space is limited.
