Product details
Overview
TLUR4401 from Vishay Semiconductors is a red visible-light LED in a standard Ø 3 mm tinted diffused T-1 package, with dominant wavelength 630 nm, luminous intensity range 4–32 mcd at 10 mA, forward voltage 2–3 V at 20 mA, and ±30° viewing angle. It supports DC and pulsed operation for status indication in industrial control panels, consumer appliance interfaces, and power-on signaling.
For engineers reviewing the TLUR4401 datasheet, TLUR4401 pinout, TLUR4401 application, or TLUR4401 equivalent, key selection criteria include luminous intensity binning (S-group: 16–32 mcd), ESD withstand voltage (2 kV per JESD22-A114-B), thermal resistance (500 K/W), reverse voltage limit (6 V), and compatibility with standard 3 mm LED mounting footprints.
Technical Context
The TLUR4401 uses GaAsP-on-GaP epitaxial technology to emit red light with dominant wavelength centered at 630 nm and peak wavelength at 640 nm. Its optical output is characterized by a ±30° half-intensity angle and diffused tinted lens for uniform visual indication under ambient lighting.
Electrically, it operates within 20 mA DC forward current and 0.5 A surge current (tp ≤ 10 μs), with junction temperature limited to 100 °C and storage temperature spanning –55 to +100 °C. Thermal resistance junction-to-ambient is 500 K/W, defining its power dissipation ceiling at 60 mW.
Key Specifications

| Dominant wavelength | 630 nm - specifies red spectral output compliant with IEC 62471 photobiological safety classification |
| Forward voltage | 2–3 V at 20 mA - determines series resistor value for constant-current drive in 3.3 V/5 V systems |
| Viewing angle | ±30° - sets angular coverage for front-panel user visibility without hot-spot glare |
| ESD withstand | 2 kV per JESD22-A114-B - indicates robustness against handling-induced electrostatic discharge |
| Reverse voltage | 6 V - defines maximum allowable reverse bias before leakage or degradation in bidirectional circuits |
| Junction capacitance | 50 pF at 0 V, 1 MHz - impacts high-frequency PWM dimming response and signal integrity in fast-switching designs |
Pinout & Package
TLUR4401 is a two-terminal through-hole LED in Ø 3 mm (T-1) tinted diffused package with cathode indicated by flat side on lens housing and shorter lead. Standard lead spacing is 2.54 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current source or microcontroller GPIO via current-limiting resistor |
| Cathode (shorter lead, flat side) | Negative terminal | Typically tied to ground or low-side switch; polarity-sensitive for correct illumination |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binned (S-group) | 16–32 mcd - enables consistent brightness matching across production batches without manual sorting |
| ESD protection level | 2 kV HBM - reduces need for external transient suppression in low-noise PCB layouts |
| Operating temperature range | –40 to +100 °C - supports deployment in automotive cabin controls and industrial HMIs without derating |
| Standard T-1 footprint | Ø 3 mm body, 2.54 mm lead pitch - ensures mechanical compatibility with legacy 3 mm LED sockets and wave-solder tooling |
| Pulse operation capability | 25 ms test pulse - allows use in multiplexed displays with duty-cycle-based brightness control |
Applications
| Industrial Control Panel Indicator | Consumer Appliance Power-On Light |

Use Value: Tinted diffused lens eliminates specular reflection off curved housing surfaces; 2 kV ESD rating prevents field failure during clinical handling and cleaning cycles. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLUR4400 | Luminous intensity range 4–15 mcd (P/Q/R bins only); no S-group (16–32 mcd) option | Lower brightness suitable for low-ambient-light environments or space-constrained indicators where glare must be minimized | Select TLUR4400 when lower intensity suffices and cost sensitivity outweighs brightness consistency requirements |
| TLHG5400 | Higher efficiency green LED (570 nm, 20–50 mcd); different dominant wavelength and material system (AlGaInP) | Used where color-coding requires green for "ready" state, not red for "power" or "fault" | Choose TLHG5400 only when spectral shift to green is required; not a functional substitute for TLUR4401's red output |
Compared with TLUR4400 and TLHG5400, the TLUR4401 delivers higher and more tightly binned red luminous intensity (S-group), enabling consistent visual feedback in bright industrial settings without increasing drive current or thermal load.

FAQ
What is the luminous intensity range of the TLUR4401 at 10 mA?
The TLUR4401 has a luminous intensity range of 4–32 mcd at 10 mA, corresponding to the S brightness bin per Vishay's classification table. This bin ensures consistent output across units shipped together, with no mixing of intensity groups within a single bag. The TLUR4401 is specifically rated for this higher-intensity range, distinguishing it from the TLUR4400 which caps at 15 mcd.
Does the TLUR4401 support pulsed operation, and what is the test pulse duration?
Yes, the TLUR4401 supports pulsed operation, and its luminous intensity is tested using a 25 ms current pulse with ±11 % measurement accuracy. This pulse duration reflects typical use in multiplexed LED arrays and microcontroller-driven blinking applications. The TLUR4401 maintains specified optical performance under these conditions without thermal saturation or wavelength shift.
What is the maximum reverse voltage rating for the TLUR4401?
The TLUR4401 has a maximum reverse voltage rating of 6 V at 25 °C, as defined in the Absolute Maximum Ratings table. Exceeding this value risks irreversible junction damage. While brief reverse conduction is permissible per note (1) in the datasheet, sustained reverse bias above 6 V is not supported. The TLUR4401 does not include integrated reverse-protection circuitry.
How is polarity identified on the TLUR4401 package?
Polarity on the TLUR4401 is identified by lead length and lens marking: the anode is the longer lead, and the cathode is the shorter lead adjacent to the flat side of the Ø 3 mm tinted diffused lens. For tape-and-reel variants like TLUR4401-AS12Z, the cathode exits the tape first, confirmed by the "AS12Z" suffix per Vishay's nomenclature guide.
What is the thermal resistance junction-to-ambient for the TLUR4401?
The TLUR4401 has a thermal resistance junction-to-ambient (RthJA) of 500 K/W, measured under standard free-air conditions. This value defines the temperature rise per unit power dissipated and confirms that the device remains within its 100 °C maximum junction temperature limit at its rated 60 mW power dissipation. Derating is required above 25 °C ambient.
