Product details
Overview
TLUR2401 from Vishay Semiconductors is a red visible-light LED in a 1.8 mm tinted diffused miniplast package, with luminous intensity of 4–32 mcd at 10 mA, dominant wavelength of 630 nm, forward voltage of 2–3 V at 20 mA, and ±20° viewing angle. It supports DC and pulse operation for front-panel status indication in industrial control panels and consumer electronics.
For engineers reviewing the TLUR2401 datasheet, TLUR2401 pinout, TLUR2401 application, or TLUR2401 equivalent, key selection criteria include luminous intensity binning (S-group: 16–32 mcd), thermal resistance (450 K/W), reverse voltage rating (6 V), junction temperature limit (100 °C), and compatibility with 2.54 mm center-to-center stackable mounting.
Technical Context
The TLUR2401 is a GaAsP-on-GaP heterostructure LED optimized for high-brightness red emission at 630 nm dominant wavelength. Its optical output is characterized by a narrow ±20° half-intensity angle and stable relative intensity across ambient temperatures up to +100 °C.
Electrically, it operates within a 20 mA DC forward current limit and withstands 6 V reverse voltage. Its 50 pF junction capacitance and 450 K/W thermal resistance reflect design priorities for low-speed indicator use with minimal thermal derating in compact enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4–32 mcd at 10 mA - defines visible brightness range for S-group binning in indicator applications |
| Dominant wavelength | 630 nm - standard red color matching human eye sensitivity peak for status visibility |
| Forward voltage | 2–3 V at 20 mA - compatible with 3.3 V and 5 V logic-level drive without external current limiting resistor redesign |
| Viewing angle | ±20° - provides focused beam for discrete panel indication with reduced crosstalk between adjacent LEDs |
| Junction temperature max | 100 °C - enables reliable operation in sealed industrial enclosures without active cooling |
| Thermal resistance | 450 K/W - determines required PCB copper area for thermal management at full 20 mA drive |
| Reverse voltage | 6 V - sufficient margin against ESD transients and back-EMF in relay-driven indicator circuits |
Pinout & Package
Package: 1.8 mm diameter tinted diffused miniplast (radial leaded, through-hole). Cathode indicated by flat side on lens and shorter lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive supply connection | Receives forward current; polarity must be observed to avoid reverse breakdown |
| Cathode (shorter lead, flat lens side) | Ground or return path | Completes current loop; marking ensures correct orientation during manual or automated assembly |
Key Features
| Feature | Design Value |
|---|---|
| End-to-end stackable mounting | Enables dense front-panel layouts with fixed 2.54 mm center-to-center spacing, reducing mechanical alignment effort |
| Luminous intensity binning (S-group) | Guarantees 16–32 mcd output at 10 mA, eliminating post-production brightness sorting for consistent visual appearance |
| Tinted diffused lens | Provides uniform light distribution and reduces glare while maintaining color saturation for clear status recognition |
| GaAsP-on-GaP semiconductor technology | Delivers stable red emission with low forward voltage and high reliability under continuous DC operation |
Applications
| Industrial Control Panel Indicators | Consumer Appliance Status Lights |
|---|---|
Use Scenario: Illuminated power-on, fault, or mode indicators on DIN-rail mounted PLC I/O modules and HMI overlays. IC Role / Device Role / Timing Role: Discrete visual status emitter requiring stable low-current DC drive and long-term lumen maintenance. Use Value: 32 mcd maximum intensity ensures legibility under factory lighting; ±20° viewing angle prevents unintended illumination of adjacent controls. | Use Scenario: Power, cycle-complete, and door-lock status lights on washing machines, microwaves, and coffee makers. IC Role / Device Role / Timing Role: Low-power, high-reliability indicator element driven directly from microcontroller GPIO pins. Use Value: 2–3 V forward voltage matches 3.3 V MCU outputs; 100 °C operating range accommodates internal appliance heat buildup. |

IC Role / Device Role / Timing Role: High-visibility discrete emitter integrated into front-panel PCBs with tight mechanical tolerances. Use Value: 1.8 mm miniplast package fits constrained board real estate; tinted diffused lens improves readability under angled viewing conditions. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLUR2400 | Luminous intensity: 4–15 mcd (R-group), lower brightness ceiling than TLUR2401's 4–32 mcd (S-group) | Suitable where lower visual impact or reduced current consumption is acceptable | Select TLUR2400 when brightness consistency across batches is prioritized over peak intensity |
| TLHR5400 | Package: 3 mm T-1, higher VF (2.1–2.5 V), wider viewing angle (±30°), same 630 nm λd | Better suited for wide-angle panel illumination; less ideal for discrete, tightly spaced indicators | Choose TLHR5400 only if board layout allows larger footprint and broader light dispersion is desired |
Compared with TLUR2400 and TLHR5400, the TLUR2401 delivers the highest certified luminous intensity (S-group) in the smallest 1.8 mm miniplast form factor, making it optimal for space-constrained, high-visibility indicator designs where precise brightness grading matters.

FAQ
What is the luminous intensity range of the TLUR2401?
The TLUR2401 has a luminous intensity range of 4–32 mcd at 10 mA, corresponding to the S-group binning per Vishay's specification. This range is measured using a 25 ms current pulse and reflects guaranteed minimum and maximum brightness levels shipped per bag, with no mixing of intensity groups.
Does the TLUR2401 support pulse-width modulation (PWM) dimming?
Yes, the TLUR2401 supports pulse operation per its datasheet features, and its 50 pF junction capacitance and fast turn-on/turn-off characteristics make it compatible with typical PWM dimming frequencies up to several kHz. However, thermal limits still apply: average power dissipation must remain ≤60 mW at Tamb ≤55 °C.
What is the cathode identification method for TLUR2401?
The TLUR2401 uses two cathode identification methods: a flat edge on the lens housing and a shorter lead length compared to the anode. These markings are consistent across all units and align with industry-standard radial LED polarity conventions for both manual and automated assembly.
Is the TLUR2401 RoHS-compliant and halogen-free?
Yes, the TLUR2401 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization documentation (ref. doc# 99912). Compliance is verified per batch and documented in the manufacturer's material declarations available upon request.
Can TLUR2401 be soldered using standard reflow profiles?
No - the TLUR2401 is a through-hole radial LED and is not rated for reflow soldering. Its specified soldering conditions are wave or hand-soldering at 260 °C for ≤3 s at 2 mm from body or ≤5 s at 4 mm from body. Reflow exposure would exceed thermal limits and damage the epoxy lens and wire bonds.
