Vishay Semiconductor Opto Division TLUR2400

Overview

TLUR2400 from Vishay Semiconductors is a red visible-light LED in a 1.8 mm tinted diffused miniplast package, with dominant wavelength 630 nm, luminous intensity 4–15 mcd at 10 mA, forward voltage 2–3 V at 20 mA, and ±20° viewing angle. It is rated for DC and pulsed operation up to 20 mA continuous forward current and used for status indication in industrial control panels and consumer device interfaces.

For engineers reviewing the TLUR2400 datasheet, TLUR2400 pinout, TLUR2400 application, or TLUR2400 equivalent, key selection factors include luminous intensity binning (P–R groups), thermal resistance (450 K/W), reverse voltage limit (6 V), junction temperature rating (100 °C), and compatibility with 2.54 mm pitch stackable mounting.

Technical Context

The TLUR2400 is a GaAsP-on-GaP heterostructure LED optimized for high-efficiency red emission at 630 nm dominant wavelength and 640 nm peak wavelength. Its 1.8 mm miniplast package features tinted diffused epoxy for uniform angular output and ±20° half-intensity angle.

It operates within -40 to +100 °C ambient range, supports 25 ms pulse testing for luminous intensity, and is categorized into discrete luminous intensity bins (P, Q, R) - with TLUR2400 specifically assigned to P (4–8 mcd) and Q (6.3–12.5 mcd) groups per shipment bag.

FAQ

What is the dominant wavelength of the TLUR2400?

The TLUR2400 has a dominant wavelength of 630 nm, which produces a standard red emission perceptible to the human eye under typical ambient lighting. This value is measured at 10 mA forward current and is consistent across all TLUR2400 units regardless of luminous intensity bin (P, Q, or R). The 630 nm specification makes the TLUR2400 suitable for applications requiring precise red color matching, such as safety-critical status indicators and industrial HMI panels.

What luminous intensity range does the TLUR2400 cover?

The TLUR2400 delivers a luminous intensity of 4–15 mcd at 10 mA, with units binned into P (4–8 mcd) and Q (6.3–12.5 mcd) groups. Each shipping bag contains only one brightness group to ensure visual consistency across assemblies. The TLUR2400 does not extend to the R (10–20 mcd) or higher bins - those are reserved for the TLUR2401 variant. This controlled binning supports repeatable optical performance in volume manufacturing.

Can the TLUR2400 be used in pulsed operation?

Yes, the TLUR2400 is explicitly rated for both DC and pulse operation. Luminous intensity is tested using a 25 ms current pulse, and the device supports surge forward current up to 0.5 A for tp ≤ 10 μs. For multiplexed display applications, designers must ensure average power dissipation stays within 60 mW and junction temperature remains below 100 °C. Pulse operation preserves LED lifetime while enabling dynamic brightness control without external drivers.

What is the maximum forward current rating for the TLUR2400?

The absolute maximum DC forward current for the TLUR2400 is 20 mA at Tamb ≤ 55 °C. Exceeding this value risks accelerated degradation or thermal runaway due to its 450 K/W junction-to-ambient thermal resistance. At elevated ambient temperatures, derating is required - e.g., ~15 mA at 85 °C. The TLUR2400 is not rated for continuous operation above 20 mA, and surge current (0.5 A) is strictly limited to ≤10 μs pulses.

Is the TLUR2400 compatible with automated PCB assembly?

Yes, the TLUR2400 is designed for automated placement with its standardized 1.8 mm miniplast package, radial leads, and clear cathode identification via flat side and shorter lead. Tape-and-reel packaging (2000 units per reel, AS12 orientation code) supports pick-and-place machines. The 2.54 mm center-to-center stackable footprint also aligns with common SMT feeder pitch requirements, enabling high-density indicator arrays without manual rework.
