Product details
Overview
TLUY2400 from Vishay Semiconductors is a yellow light-emitting diode (LED) in a 1.8 mm tinted diffused miniplast package, with dominant wavelength 581–594 nm, luminous intensity 1–8 mcd at 10 mA, forward voltage 2.4–3 V at 20 mA, and ±20° viewing angle - used for status indication in industrial control panels and consumer appliance interfaces.
For engineers reviewing the TLUY2400 datasheet, TLUY2400 pinout, TLUY2400 application, or TLUY2400 equivalent, this page delivers verified optical-electrical specs, thermal limits, packaging details, and direct alternative options for indicator LED selection in space-constrained, low-power DC or pulsed designs.
Technical Context
The TLUY2400 is a GaAsP-on-GaP heterostructure LED optimized for visible yellow emission with tight wavelength binning (581–594 nm dominant, 585 nm peak) and calibrated luminous intensity grading per Vishay's L/M/N/P/Q/R/S classification system. It operates under DC or pulsed conditions up to 30 mA continuous forward current.
Its thermal resistance junction-to-ambient is 450 K/W, enabling operation from –40 °C to +100 °C ambient, with maximum junction temperature of 100 °C and reverse voltage rating of 6 V - consistent across the TLUO/TLUY/TLUG240 family.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Yellow (dominant wavelength 581–594 nm) |
| Luminous intensity | 1–8 mcd at 10 mA - defines visible brightness level for front-panel status indication |
| Forward voltage | 2.4–3 V at 20 mA - determines series resistor value for 3.3 V or 5 V supply rail designs |
| Viewing angle | ±20° half-intensity - provides narrow, directional visibility suitable for discrete indicator placement |
| Absolute max forward current | 30 mA - sets upper limit for continuous drive without derating |
| Junction-to-ambient thermal resistance | 450 K/W - constrains power dissipation to ≤100 mW at Tamb ≤ 55 °C |
| Operating temperature | –40 to +100 °C - supports deployment in industrial enclosures and automotive cabin environments |
Pinout & Package
TLUY2400 uses a standard 2-pin axial leaded miniplast package (Ø1.8 mm), with cathode indicated by flat side or shorter lead. No polarity marking on lens; mechanical polarity identification required during PCB layout and assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor and supply rail; forward bias enables photon emission |
| Cathode (shorter lead / flat side) | Negative terminal | Reference node for current return path; must be tied to ground or driver sink |
Key Features
| Feature | Design Value |
|---|---|
| End-to-end stackable design | Center-to-center spacing of 2.54 mm enables compact linear LED arrays without custom mounting fixtures |
| Luminous intensity categorization | Shipped in single brightness group per bag (e.g., L-group: 1–2 mcd), ensuring consistent visual output across production batches |
| Tinted diffused lens | Reduces glare and provides uniform Lambertian emission profile for improved readability at off-axis angles |
| GaAsP-on-GaP chip technology | Delivers stable yellow chromaticity with low wavelength drift over temperature and lifetime |
Applications
| Industrial Control Panel Indicator | Consumer Appliance Status Light |
|---|---|
Use Scenario: Visual feedback for power-on, fault, or mode status on DIN-rail mounted PLC I/O modules. IC Role / Device Role / Timing Role: Discrete optical indicator driven directly from microcontroller GPIO or logic buffer output. Use Value: ±20° viewing angle ensures clear visibility within panel cutouts; 1–8 mcd intensity balances visibility and eye comfort at typical 10–30 cm viewing distance. |
Use Scenario: Power and cycle completion indication on microwave ovens, washing machines, and coffee makers. IC Role / Device Role / Timing Role: Low-power DC-driven status emitter interfaced via series resistor to 3.3 V or 5 V MCU output. Use Value: Tinted diffused lens prevents hot-spot glare; operating range down to –40 °C supports storage in unheated retail environments. |
| Medical Device Power Indicator | Test Equipment Function Mode Display |
Use Scenario: Non-critical power-on confirmation on Class II portable diagnostic tools with no battery charging circuitry. IC Role / Device Role / Timing Role: Standalone LED connected to regulated 3.3 V rail with fixed 220 Ω current-limiting resistor. Use Value: 30 mA absolute max rating allows margin for transient overcurrent; RoHS/halogen-free construction meets IEC 60601-1 collateral standard requirements. |
Use Scenario: Mode selection feedback (e.g., "AC Voltage", "Continuity") on handheld multimeters and signal generators. IC Role / Device Role / Timing Role: Pulsed operation at 1 kHz duty cycle to reduce average power while maintaining perceived brightness. Use Value: 50 pF junction capacitance minimizes high-frequency switching distortion; 450 K/W RthJA supports sustained pulsing without thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLUY2401 | Higher luminous intensity (2.5–12.5 mcd at 10 mA) - same package, wavelength, and VF range | Better suited for applications requiring higher visibility in ambient-lit environments | Select TLUY2401 when >2.5 mcd minimum intensity is needed; TLUY2400 remains optimal for low-light or glare-sensitive use cases |
| TLUG2400 | Green emission (562–575 nm dominant), identical package, VF, and thermal specs | Used where color-coding requires green for "ready" or "normal" states per IEC 60417 conventions | Choose TLUG2400 for standardized green status coding; TLUY2400 maintains yellow for caution/warning per ISO 3864-1 |
Compared with TLUY2401 and TLUG2400, the TLUY2400 offers the lowest luminous intensity tier in its family while retaining identical mechanical fit, thermal behavior, and drive compatibility - making it ideal for cost-sensitive, low-brightness indicator roles where visual differentiation is maintained via color rather than intensity.

FAQ
What is the dominant wavelength range of the TLUY2400?
The TLUY2400 has a dominant wavelength range of 581–594 nm, measured at 10 mA forward current. This places its yellow emission precisely within the CIE 1931 chromaticity region for standardized warning/yellow indication. The peak wavelength is 585 nm, confirming spectral centering in the yellow band. All values are specified per Vishay Document Number 83053 Rev. 2.6.
What is the maximum continuous forward current rating for the TLUY2400?
The TLUY2400 is rated for a maximum DC forward current of 30 mA at ambient temperatures ≤55 °C. Exceeding this value without thermal derating risks accelerated lumen depreciation and potential junction failure. The device also supports surge forward current up to 1 A for pulses ≤10 μs, enabling brief pulse-drive applications.
Does the TLUY2400 have a diffused or clear lens?
The TLUY2400 features a tinted diffused lens, as explicitly stated in the Vishay datasheet header: "Universal LED, Ø 1.8 mm Tinted Diffused Miniplast Package." This optical treatment produces a Lambertian emission pattern that softens intensity gradients and improves off-axis visibility compared to clear-lens variants.
Is the TLUY2400 RoHS and halogen-free compliant?
Yes, the TLUY2400 is RoHS-compliant and halogen-free, as confirmed by Vishay's environmental symbols (M) on the fan-fold box label and referenced in Document Number 91000. Compliance is verified per EU Directive 2011/65/EU and IEC 61249-2-21, with full material declarations available upon request.
What is the thermal resistance junction-to-ambient (RthJA) for the TLUY2400?
The TLUY2400 has a thermal resistance junction-to-ambient of 450 K/W, measured under standard conditions (Tamb ≤ 55 °C). This value reflects the inherent thermal limitation of its 1.8 mm miniplast package and dictates that power dissipation must remain ≤100 mW to avoid exceeding the 100 °C maximum junction temperature.
