Product details
Overview
TLHR5400 from Vishay Semiconductors is a red 5 mm tinted diffused LED with dominant wavelength 612–630 nm, luminous intensity 1.6–10 mcd at 10 mA, forward voltage 2–3 V at 20 mA, ±30° viewing angle, and GaAsP-on-GaP technology-designed for status indication and legend lighting in industrial control panels.
For engineers reviewing the TLHR5400 datasheet, TLHR5400 pinout, TLHR5400 application, or TLHR5400 equivalent, this page delivers verified optical/electrical specs, package geometry, thermal limits, luminous intensity binning, and direct alternatives for indicator LED selection in cost-sensitive, high-reliability DC-driven UI applications.
Technical Context
The TLHR5400 operates as a standard through-hole indicator LED with cathode-anode polarity, rated for 30 mA DC forward current and 1 A surge (10 μs), junction-to-ambient thermal resistance of 350 K/W, and operating ambient range from –40 °C to +100 °C. Its 5 mm T-1¾ package features stand-offs and mechanical tolerances optimized for automated insertion and consistent board-level alignment.
Optical performance is defined by dominant wavelength (612–630 nm), peak wavelength (~635 nm), and angular distribution with half-intensity at ±30°, enabling high on-off contrast in panel-mounted status lights. Luminous intensity is binned per group M (1.6–3.2 mcd) to ensure visual uniformity across assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Red - matches human visual sensitivity peak for status alerts and meets IEC 60417-5009/5010 symbol illumination requirements. |
| Luminous intensity | 1.6–10 mcd at 10 mA - supports low-power indicator operation while maintaining visibility under typical indoor ambient lighting. |
| Dominant wavelength | 612–630 nm - ensures consistent red hue across production lots; binned for color-matching in multi-LED arrays. |
| Viewing angle | ±30° - provides wide, uniform illumination for front-panel indicators viewed from multiple angles. |
| Forward voltage | 2–3 V at 20 mA - compatible with common 3.3 V and 5 V logic-supplied current-limiting resistor designs. |
| Absolute max forward current | 30 mA continuous - enables robust operation in industrial environments with transient overcurrent events. |
| Junction temperature limit | 100 °C - defines maximum allowable die temperature under sustained drive; requires thermal derating above 65 °C ambient. |
Pinout & Package
TLHR5400 uses a standard 2-pin through-hole 5 mm T-1¾ package with axial leads. Cathode is identified by flat side on lens and shorter lead; anode is longer lead. Stand-offs ensure consistent PCB standoff height during wave soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor and supply rail; must be driven at ≥2 V to achieve rated luminance. |
| Cathode (shorter lead, flat lens side) | Negative terminal | Common return path; polarity reversal beyond 6 V reverse voltage risks permanent junction damage. |
Key Features
| Feature | Design Value |
|---|---|
| 5 mm tinted diffused lens | Softens point-source glare and improves readability of status indicators under varied lighting conditions. |
| Luminous intensity binning (Group M) | Ensures ≤0.5 ratio between min/max IV in same packing unit-critical for uniform brightness in multi-LED panels. |
| Stand-off design | Maintains precise 2.54 mm PCB standoff height, preventing mechanical stress during board flex or thermal cycling. |
| GaAsP-on-GaP semiconductor | Delivers stable red emission with low temperature coefficient of wavelength drift (<0.1 nm/°C). |
| Rated for high peak current (1 A, 10 μs) | Supports pulsed drive schemes for enhanced brightness without thermal runaway in multiplexed displays. |
Applications
| Status Indicator | Legend Illumination |
|---|---|
Use Scenario: Front-panel power-on or fault condition indication on industrial PLCs and HMI enclosures. IC Role / Device Role / Timing Role: Visual status emitter - no timing or signal processing role; driven statically or via GPIO-controlled current source. Use Value: High on-off contrast and ±30° viewing angle ensure immediate operator recognition from 0.5–2 m distance under factory lighting. |
Use Scenario: Backlighting engraved labels on control panels (e.g., "RUN", "STOP", "ALARM") in medical devices and test equipment. IC Role / Device Role / Timing Role: Passive light source - no active control interface; relies on fixed-resistor biasing for constant luminance. Use Value: Tinted diffused lens eliminates hot spots and provides even illumination across 3–5 mm character widths. |
| Readout Light | Maintenance Indicator |
Use Scenario: Local readout illumination for analog meters and digital displays in field instruments (e.g., multimeters, pressure gauges). IC Role / Device Role / Timing Role: Ambient-light-compensated visual aid - operated continuously at 10 mA for low self-heating and stable output. Use Value: 1.6–10 mcd output balances visibility against power consumption in battery-backed portable instruments. |
Use Scenario: Service-mode indicator on telecom chassis or network switches to signal maintenance access or firmware update status. IC Role / Device Role / Timing Role: Low-duty-cycle blink source - driven with 100 Hz PWM to extend lifetime while retaining perceptible flash rate. Use Value: 1 A surge rating allows safe 100 μs pulse drive at 2× nominal current, increasing flash intensity without degrading junction life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red indicator LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHR5401 | Luminous intensity 4–12 mcd (Group N) - ~2.5× higher typical output than TLHR5400. | Better suited for applications requiring higher visibility in bright ambient or longer viewing distances. | Select TLHR5401 when >3 mcd minimum intensity is required; verify current-limiting resistor recalibration for 12 mcd typ. output. |
| TLHR5405 | Luminous intensity 6.3–14 mcd (Group P) - ~4× higher typical output; same wavelength and VF range. | Preferred for high-contrast legend lighting where adjacent LEDs must match within tight binning tolerance. | Choose TLHR5405 for applications demanding >6 mcd minimum intensity and tighter luminance uniformity across batches. |
Compared with TLHR5400, TLHR5401 and TLHR5405 offer progressively higher luminous intensity while retaining identical package, pinout, wavelength, forward voltage, and thermal ratings-enabling drop-in brightness upgrades without layout or driver changes.

FAQ
What is the exact luminous intensity range of TLHR5400 at 10 mA?
The TLHR5400 has a luminous intensity range of 1.6–10 mcd at 10 mA, corresponding to Group M binning per Vishay's classification table. This range ensures visual uniformity within each packaging unit, where the ratio of minimum to maximum intensity does not exceed 0.5. The TLHR5400 is not rated for intensity above 10 mcd at 10 mA.
Does TLHR5400 support pulsed operation, and what are its surge limits?
Yes, TLHR5400 supports pulsed operation with a surge forward current rating of 1 A for pulses ≤10 μs. This enables high-brightness flashing in multiplexed displays without exceeding junction temperature limits. The TLHR5400 must be operated below 30 mA DC and derated linearly above 65 °C ambient temperature.
What is the package type and lead configuration of TLHR5400?
TLHR5400 uses a 5 mm T-1¾ through-hole package with axial leads and stand-offs. The anode is the longer lead; the cathode is marked by both the shorter lead and a flat edge on the lens. Lead pitch is 2.54 mm, and body diameter is 5.0 ± 0.15 mm per Vishay's mechanical drawing.
How does TLHR5400's dominant wavelength compare to TLHY5400?
TLHR5400 has a dominant wavelength range of 612–630 nm (red), while TLHY5400 is yellow with 581–594 nm. These are distinct spectral bands with no overlap; TLHR5400 cannot substitute for yellow indication requirements. Both share identical package, viewing angle, and forward voltage ranges but differ in semiconductor material bandgap and optical output.
Is TLHR5400 RoHS-compliant and halogen-free?
Yes, TLHR5400 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay's material categorization standard (document 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.
