Product details

Overview

TLUR5400 from Vishay Semiconductors is a red visible-light LED in a standard 5 mm Tinted Diffused (T-1¾) package, with dominant wavelength 630 nm, luminous intensity 4–15 mcd at 10 mA, forward voltage 2–3 V at 20 mA, and ±30° viewing angle. It serves as an indicator light in panel-mounted status displays requiring stable low-current DC operation.

For engineers reviewing the TLUR5400 datasheet, TLUR5400 pinout, TLUR5400 application, or TLUR5400 equivalent, key selection criteria include luminous intensity binning, GaAsP-on-GaAs material compatibility with 5 V logic interfaces, thermal resistance of 500 K/W, and compliance with industrial ambient temperature range (−40 °C to +100 °C).

Technical Context

The TLUR5400 is a through-hole, two-terminal semiconductor diode emitting red light via electroluminescence in a GaAsP-on-GaAs heterostructure. Its optical output is characterized by a dominant wavelength of 630 nm and peak wavelength of 640 nm, with angular distribution defined by ±30° half-intensity angle.

Electrically, it operates under DC or pulsed forward bias up to 20 mA continuous current (1 A surge for ≤10 μs), with reverse voltage rating of 6 V and junction-to-ambient thermal resistance of 500 K/W - indicating suitability for passive heatsinking in compact enclosures.

Equivalent & Alternatives

The following parts are listed as comparable options for similar red LED indicator applications.

Alternative PartTechnical DifferenceApplication DifferenceSelection Advice
Kingbright A-501SURKSame 5 mm package, but 625 nm dominant wavelength and 12–24 mcd at 20 mA - higher intensity, narrower spectral peakPreferred where higher brightness or tighter wavelength tolerance is required; not binned to IVmin/IVmax ≤ 0.5Select A-501SURK when absolute brightness uniformity is less critical than raw output level
Vishay TLHR5400Identical package and pinout, but hyper-red (660 nm) with 2–8 mcd at 10 mA - lower intensity, deeper red spectrumSuitable for applications requiring photobiological safety or IR-adjacent detection; not interchangeable for color-matching with TLUR5400Choose TLHR5400 only when spectral shift toward infrared is functionally required

Compared with TLUR5400, A-501SURK delivers higher luminous intensity but lacks intensity binning control, while TLHR5400 shifts wavelength significantly and reduces output - neither offers drop-in replacement capability without optical or electrical recalibration.

FAQ

What is the maximum continuous forward current rating for TLUR5400?

The TLUR5400 has a maximum DC forward current rating of 20 mA at ambient temperatures ≤65 °C. Exceeding this value risks accelerated degradation and irreversible luminous flux loss. Derating is required above 65 °C ambient, as shown in Figure 1 of the Vishay datasheet (Doc. #83055). Always verify thermal design margins using the 500 K/W junction-to-ambient resistance when integrating TLUR5400 into enclosed assemblies.

Does TLUR5400 require current-limiting circuitry?

Yes, TLUR5400 requires a series current-limiting resistor or constant-current driver. With a forward voltage range of 2–3 V at 20 mA, the resistor value must be calculated based on supply voltage and desired operating current - e.g., for 5 V supply and 10 mA operation, a 200 Ω resistor is typical. Omitting current limiting will cause immediate thermal runaway and permanent failure of the TLUR5400.

Is TLUR5400 RoHS compliant and halogen-free?

Yes, TLUR5400 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (see Doc. #99912). The device contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE), and all bromine/chlorine content is below 900 ppm. Full compliance documentation is available upon request for TLUR5400.

What is the meaning of "luminous intensity categorized" for TLUR5400?

"Luminous intensity categorized" means TLUR5400 units are binned during manufacturing so that IVmin/IVmax ≤ 0.5 within each packing unit - ensuring brightness consistency across LEDs in the same reel or bulk pack. This binning supports predictable visual matching in multi-LED arrays and avoids manual sorting. The TLUR5400 specification sheet confirms this applies to the exact part number TLUR5400, not just the family.

Can TLUR5400 be used in outdoor applications?

TLUR5400 is rated for −40 °C to +100 °C operating temperature but lacks IP-rated encapsulation or UV-stabilized lens material. It may be used outdoors only if fully protected from moisture, dust, and direct UV exposure - e.g., behind sealed polycarbonate windows in instrument housings. Unprotected outdoor mounting will degrade the tinted diffused epoxy lens and reduce TLUR5400 luminous output over time.
