59-23UWD/TR8

Overview

The 59-23UWD/TR8 is a white light-emitting diode manufactured by Everlight Electronics Co Ltd. It features a top-view configuration with a diffused lens and is housed in an SMD package. The component operates with a typical forward voltage of 3.2V and a test current of 20mA. It provides a viewing angle of 50 degrees and delivers a luminous intensity of 11,000 mcd. The physical dimensions are 4.00mm in length, 4.00mm in width, and a maximum height of 1.50mm.

Feature Summary

• Top-view LED design with a diffused lens for uniform light distribution
• Standard surface-mount package suitable for automated placement equipment
• RoHS compliant construction without lead content

Applications

• General indicator lighting
• Backlighting for switches and symbols
• Illumination for LCD displays

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required binning parameters such as forward voltage and chromaticity coordinates. Confirm that the tape and reel packaging meets the specifications of your automated assembly machinery. Check for any recent product change notifications regarding material or process updates before finalizing procurement orders.

Selection Notes

Select this component when a standard white SMD LED with a 50-degree viewing angle is required. Ensure the circuit design accommodates the 3.2V forward voltage drop at the target operating current. Verify that the 4.00mm x 4.00mm footprint fits within the available board space constraints.

Part Context

This part belongs to Everlight's series of top-view LEDs designed for general illumination and indication purposes. The 59-series typically utilizes phosphor-coated chips to produce white light output. These components are engineered for high reliability and consistent performance in consumer electronics and industrial applications requiring compact light sources.
