Product details
Overview
TLUY2401 from Vishay Semiconductors is a yellow 1.8 mm miniplast LED with dominant wavelength 581–594 nm, luminous intensity 2.5–12.5 mcd at 10 mA, forward voltage 2.4–3.0 V at 20 mA, ±20° viewing angle, and GaAsP-on-GaP chip technology - used for status indication in industrial control panels and consumer appliance interfaces.
For engineers reviewing the TLUY2401 datasheet, TLUY2401 pinout, TLUY2401 application, or TLUY2401 equivalent, key selection criteria include luminous intensity binning (N-group: 2.5–5 mcd), DC/pulse operation capability, thermal resistance of 450 K/W, and compatibility with 2.54 mm pitch stackable mounting.
Technical Context
The TLUY2401 employs a GaAsP-on-GaP heterostructure emitting in the yellow spectrum (λd = 586 nm typ.), with junction capacitance ≤50 pF at 0 V and 1 MHz. Its optical output is characterized by a Lambertian radiation pattern and ±20° half-intensity angle.
Rated for 30 mA DC forward current and 1 A surge (tp ≤ 10 μs), it operates across –40 °C to +100 °C ambient and maintains luminous output stability up to 55 °C case temperature, supported by 450 K/W junction-to-ambient thermal resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Yellow (dominant wavelength 581–594 nm) |
| Luminous intensity | 2.5–12.5 mcd at 10 mA - defines visible brightness level for human-readable status indication |
| Forward voltage | 2.4–3.0 V at 20 mA - determines series resistor value and power dissipation in constant-current drive |
| Viewing angle | ±20° half-intensity - specifies angular visibility range for front-panel mounting |
| Package | 1.8 mm miniplast (Tinted Diffused) - provides mechanical robustness and uniform light diffusion |
| Thermal resistance | 450 K/W junction-to-ambient - limits maximum continuous current under natural convection cooling |
| Absolute max forward current | 30 mA DC - sets upper bound for reliable long-term operation without derating |
Pinout & Package
TLUY2401 uses a standard 2-pin axial lead miniplast package (Ø1.8 mm) with cathode indicated by flat side or shorter lead. No polarity marking on lens; mechanical polarity identification required during placement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connected to current-limiting resistor and supply rail; reverse bias must not exceed 6 V |
| Cathode (shorter lead / flat side) | Negative terminal | Common return path; requires proper PCB silkscreen or assembly documentation for orientation |
Key Features
| Feature | Design Value |
|---|---|
| End-to-end stackable | Enables compact multi-LED arrays with 2.54 mm center-to-center spacing - reduces board area in indicator banks |
| Luminous intensity binning | N-group (2.5–5 mcd) ensures consistent brightness within a single bag - eliminates manual sorting in high-volume assembly |
| DC and pulse operation | Rated for continuous 30 mA or pulsed 1 A (≤10 μs) - supports both static indicators and multiplexed displays |
| Tinted diffused lens | Minimizes glare and provides uniform illumination - improves readability under varying ambient lighting |
| RoHS-compliant & halogen-free | Meets IEC 61249-2-21 and JEDEC J-STD-609A Class 1 - supports environmental compliance in global electronics markets |
Applications
| Industrial Control Panel Indicators | Consumer Appliance Status Lights |
|---|---|
Use Scenario: Front-panel power-on, fault, and mode indicators on PLC I/O modules and HMI enclosures. IC Role / Device Role / Timing Role: Discrete visual status emitter - no timing or logic function; driven directly by microcontroller GPIO or discrete transistor switch. Use Value: High-visibility yellow output (586 nm typ.) delivers optimal contrast against gray/black industrial bezels under factory lighting conditions. |
Use Scenario: Cycle-complete, door-lock, and temperature-ready indicators on washing machines and microwaves. IC Role / Device Role / Timing Role: Standalone optoelectronic indicator - electrically isolated from main controller via current-limiting resistor. Use Value: 2.5–12.5 mcd luminous intensity ensures legibility at typical viewing distances (0.5–1.5 m) without excessive power draw. |
| Test Equipment Power-On Verification | Medical Device Ready-State Signaling |
Use Scenario: "Power Applied" confirmation LED on bench multimeters and oscilloscope front panels. IC Role / Device Role / Timing Role: Passive current-driven light source - no internal regulation or communication interface. Use Value: ±20° viewing angle provides consistent brightness across wide operator viewing angles in lab environments. |
Use Scenario: Non-critical ready/standby indicators on diagnostic ultrasound consoles and infusion pump interfaces. IC Role / Device Role / Timing Role: Visual feedback element only - no safety-critical function; complies with IEC 60601-1 basic insulation requirements. Use Value: Operating temperature range (–40 °C to +100 °C) supports reliability in thermally variable clinical settings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLUY2400 | Luminous intensity: 1–8 mcd (L-group) - lower brightness bin than TLUY2401's N-group | Suitable where reduced visibility or lower power consumption is acceptable | Select TLUY2400 only if system-level brightness tolerance allows down-binning; not interchangeable without optical validation |
| TLUG2401 | Green emission (562–575 nm), same package and IF/VF ratings - different chromaticity and photopic response | Used where color-coding requires green for "ready" or "normal" states per IEC 61310 | Choose TLUG2401 when application mandates green instead of yellow; identical mechanical fit but distinct optical function |
Compared with TLUY2400 and TLUG2401, the TLUY2401 offers mid-range yellow luminous intensity (2.5–12.5 mcd) optimized for balanced visibility and power efficiency, whereas TLUY2400 targets low-brightness cost-sensitive use, and TLUG2401 serves chromatically distinct green signaling roles.

FAQ
What is the luminous intensity range of the TLUY2401 at 10 mA?
The TLUY2401 has a luminous intensity range of 2.5–12.5 mcd at 10 mA, corresponding to the N-group binning classification per Vishay's specification document 83053. This range ensures consistent brightness within a given packaging unit and supports predictable optical design in indicator applications. The TLUY2401's specified intensity is measured using a 25 ms current pulse and carries ±11% test accuracy.
Does the TLUY2401 support pulsed operation, and what are the limits?
Yes, the TLUY2401 supports pulsed operation with a surge forward current rating of 1 A for pulse widths ≤10 μs. It is also rated for continuous DC operation up to 30 mA. Pulse operation enables time-multiplexed display architectures while maintaining thermal safety, provided duty cycle and average power remain within the 100 mW dissipation limit. The TLUY2401's junction capacitance of ≤50 pF supports fast switching in such configurations.
What is the forward voltage range for the TLUY2401, and at what test condition is it specified?
The forward voltage for the TLUY2401 is specified as 2.4–3.0 V at 20 mA DC, per the Absolute Maximum Ratings and Optical/Electrical Characteristics tables in Vishay document 83053. This range reflects process variation across production lots and informs series resistor selection for constant-current drive circuits. The TLUY2401's VF remains stable across its operating temperature range (–40 °C to +100 °C).
Is the TLUY2401 RoHS-compliant and halogen-free?
Yes, the TLUY2401 is RoHS-compliant and halogen-free, meeting IEC 61249-2-21 and JEDEC J-STD-609A Class 1 standards. Environmental compliance symbols (RoHS, Pb-free, halogen-free) appear on the fan-fold box label per Vishay's packaging documentation. The TLUY2401's material categorization is defined in Vishay document 99912, and full compliance data is available through Vishay's material declarations portal.
How is polarity identified on the TLUY2401 package?
Polarity on the TLUY2401 is identified mechanically: the cathode is marked by the shorter lead and/or a flat edge on the cylindrical miniplast body. The lens itself carries no polarity marking, so correct orientation must be verified during PCB layout and assembly. The TLUY2401's absolute maximum reverse voltage is 6 V, making accurate polarity assignment essential to prevent junction damage during installation or testing.
