The SML-D12V1WT86 is a compact surface-mounted device (SMD) LED that comes in a 0603 package size, which is 1.6 x 0.8mm with a thickness of 0.55mm. This LED emits red light in the wavelength range of 625 to 635nm, with a typical forward voltage (VF) of 2.2V when driven at a forward current (IF) of 20mA. It is designed for high reliability and performance, featuring moisture sensitivity level (MSL) 3, making it suitable for a wide range of environmental conditions.
The LED is constructed using AlGaInP chip technology, which provides excellent efficiency and light output. It supports a peak forward current (IFP) of 100mA (duty 1/10, 1kHz), allowing for flexible use in various pulsing applications. The luminous intensity (IV) ranges from 40 to 63 mcd at IF=20mA, indicating the brightness of the LED under standard operating conditions. The device is also characterized by a broad viewing angle, making it ideal for applications requiring wide light distribution.
LED
Light Emitting Diodes (LEDs) are semiconductor devices that emit light when an electric current passes through them. They are widely used in a variety of applications due to their efficiency, long life, and the ability to produce light in different colors. LEDs are available in various packages, including surface-mounted device (SMD) types, which are popular for their compact size and ease of integration into electronic circuits.
When selecting an LED for a specific application, important factors to consider include the color or wavelength of light emitted, forward voltage and current, luminous intensity, viewing angle, and package size. The choice of LED technology, such as AlGaInP or InGaN, also affects performance characteristics like efficiency and color range. Additionally, moisture sensitivity level (MSL) is an important consideration for the storage and handling of LEDs, especially in environments prone to humidity.
LEDs are employed in a wide range of applications, from simple indicator lights to complex lighting systems. Their low power consumption, long lifespan, and reliability make them suitable for use in consumer electronics, automotive lighting, general illumination, and signaling. The ability to precisely control the brightness and color of LEDs also allows for innovative uses in displays, mood lighting, and medical devices.
Overall, the selection of an LED involves balancing technical specifications with application requirements. Engineers must consider the electrical and optical characteristics of an LED, as well as environmental and mechanical constraints, to ensure optimal performance and reliability in the intended application.
