What are the key features of LS T676-R1S1-1?
- 633 nm red emission wavelength optimized for status indicators and visible optical feedback in human-machine interfaces
- PLCC-2 surface-mount package enables automated reflow assembly on high-density PCBs
- Round lens design provides wide-angle light distribution for broad viewing angle indicator applications
- TOPLED Series construction offers consistent binning and color matching across production lots
- Low forward voltage operation compatible with 3.3 V and 5 V logic-level drive circuits with a single current-limiting resistor
What is LS T676-R1S1-1 used for?
The LS T676-R1S1-1 is commonly used as a status indicator LED in network switches, industrial controllers, and consumer appliances where a compact SMD red LED must convey fault, power, or activity states to operators. Its 633 nm wavelength aligns with human photopic vision sensitivity for red, providing high perceived brightness at moderate forward currents of 10 mA to 20 mA. The PLCC-2 package and round lens also make it suitable for light pipe coupling and diffuse backlighting in panel displays and keyboard indicators.

Frequently Asked Questions
At what forward current does the LS T676-R1S1-1 achieve rated luminous intensity, and how is drive current set?
The OSRAM TOPLED LS T676-R1S1-1 is typically characterized at a forward current of 20 mA, at which it reaches its rated luminous intensity. To drive it from a 3.3 V logic output, a current-limiting resistor of approximately 160 Ω is required, calculated as (3.3 V – 2.0 V) / 20 mA, assuming a typical red LED forward voltage of about 2.0 V.
How does the 633 nm emission wavelength of the LS T676-R1S1-1 compare to orange and deep red LEDs for indicator visibility?
The 633 nm wavelength falls in the red region of the visible spectrum near the peak of human photopic response for red, which is approximately 625–640 nm, giving the LS T676-R1S1-1 good perceived brightness efficiency per milliwatt of optical power. Orange LEDs near 610 nm appear brighter under the same conditions, while deep red LEDs above 660 nm produce less luminous efficiency but better photosensor coupling in near-IR proximity sensing circuits.
For a light pipe indicator application, what beam angle does the round lens of the LS T676-R1S1-1 provide?
The round lens on the LS T676-R1S1-1 provides a diffuse emission pattern with a typical half-intensity viewing angle of approximately ±60°, making it suitable for coupling into large-diameter light pipes or side-lit diffusers where wide angular emission is needed. Applications requiring a narrower beam for direct-view light pipes may need a lens-coupled variant or external collimating optic to achieve viewing angles below ±30°.
