Product details
Overview
TLHR6405 from Vishay Semiconductors is a red light-emitting diode (LED) in a 5 mm tinted diffused T-1¾ package, delivering 6.3–14 mcd luminous intensity at 10 mA, with dominant wavelength 612–630 nm, ±30° viewing angle, and forward voltage of 2–3 V at 20 mA - used for status indication, legend lighting, and panel-mounted on/off indicators.
For engineers reviewing the TLHR6405 datasheet, TLHR6405 pinout, TLHR6405 application, or TLHR6405 equivalent, this page provides verified optical/electrical specs, package dimensions, absolute maximum ratings, and real-world selection guidance for industrial indicator and front-panel lighting designs.
Technical Context
The TLHR6405 is a GaAsP-on-GaP heterostructure LED optimized for high on-off contrast in ambient-light environments. Its ±30° half-intensity angle and diffused lens ensure uniform illumination across wide viewing zones without hotspots.
Rated for DC and pulsed operation up to 1 A surge current (tp ≤ 10 μs), it supports reliable operation from −40 °C to +100 °C ambient, with thermal resistance of 350 K/W and junction temperature limit of 100 °C - enabling use in sealed enclosures and thermally constrained panels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 6.3–14 mcd at 10 mA - ensures clear visibility at typical panel distances without excessive current draw |
| Dominant wavelength | 612–630 nm - standard red spectral output compatible with human visual acuity and color-coding standards |
| Viewing angle | ±30° - enables broad coverage for user-facing indicators without requiring precise alignment |
| Forward voltage | 2–3 V at 20 mA - compatible with common 3.3 V and 5 V logic-supplied current-limiting resistor networks |
| Absolute max forward current | 30 mA continuous - defines safe DC drive level for long-term reliability in 24/7 status lights |
| Reverse voltage | 6 V - sets minimum reverse-bias protection requirement for PCB-level ESD or polarity-reversal safeguards |
| Junction capacitance | ≤50 pF at 0 V - negligible impact on switching speed in static or low-frequency indicator applications |
Pinout & Package
TLHR6405 uses a standard 5 mm T-1¾ radial-leaded package with cathode-indicating flat edge and shorter lead. Package outline conforms to DIN specifications with 2.54 mm lead pitch, 5.0 mm lens diameter, and 8.7 mm overall height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor and supply rail; polarity must be observed to avoid damage |
| Cathode (shorter lead, flat side) | Negative terminal | Reference node for current return; marked by physical flat on lens housing and shorter lead |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | Ensures consistent brightness across multiple units in same assembly - critical for uniform panel appearance |
| Tinted diffused lens | Eliminates glare and provides soft, even emission - improves readability under direct lighting |
| Wide operating temperature range | −40 °C to +100 °C ambient - supports deployment in industrial control cabinets and outdoor-rated enclosures |
| High surge current tolerance | 1 A peak for 10 μs - withstands transient inrush during power-up or relay-coil switching events |
| RoHS-compliant materials | Lead-free, halogen-free construction - meets global environmental compliance requirements for end-product certification |
Applications
| Status Indicator | Legend Illumination |
|---|---|
Use Scenario: Front-panel LED showing system power-on state in industrial HMIs or test equipment. IC Role / Device Role / Timing Role: Discrete visual indicator driven directly from microcontroller GPIO or dedicated driver IC. Use Value: High 6.3–14 mcd output and ±30° viewing angle ensure legibility across operator positions without backlighting or optics. | Use Scenario: Backlighting engraved labels on membrane switches or control panels. IC Role / Device Role / Timing Role: Low-power, steady-state emitter placed behind translucent legend areas. Use Value: Tinted diffused lens delivers uniform, non-glare illumination ideal for text/shape definition without hotspots. |
| Readout Light | Maintenance Indicator |
Use Scenario: Localized lighting for analog meter scales or digital display digits in low-ambient-light settings. IC Role / Device Role / Timing Role: Constant-current-driven discrete LED adjacent to readout surface. Use Value: 612–630 nm red output enhances contrast against black/white markings while minimizing eye fatigue. | Use Scenario: Service-mode indicator on field-deployed instrumentation, visible only during maintenance access. IC Role / Device Role / Timing Role: Low-duty-cycle, manually triggered visual flag for technician diagnostics. Use Value: 30 mA absolute max rating and −40 °C to +100 °C operation support intermittent use in unconditioned environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHR6401 | Luminous intensity 4–12 mcd (lower than TLHR6405's 6.3–14 mcd); otherwise identical package, wavelength, and electrical specs | Suitable where reduced brightness suffices for lower power or glare-sensitive locations | Select TLHR6401 when panel density requires lower intensity to avoid visual overload or when driving from weak GPIO sources |
| TLHR6405-ASZ | Identical optical/electrical specs; differs only in packaging - supplied in ammopack (5 × 1000) with anode-first orientation labeling | Used when automated pick-and-place requires standardized tape orientation and traceable batch labeling | Choose TLHR6405-ASZ for SMT-compatible reel-fed assembly; TLHR6405 is bulk or tape-and-reel without orientation coding |
Compared with TLHR6401 and TLHR6405-ASZ, the TLHR6405 offers the highest standard luminous intensity in its series while retaining full compatibility with legacy 5 mm through-hole layouts and drive circuits - making it optimal for new designs prioritizing visibility without redesign.

FAQ
What is the luminous intensity range of TLHR6405 at 10 mA?
The TLHR6405 delivers a luminous intensity of 6.3–14 mcd at 10 mA forward current, measured under standard conditions (Tamb = 25 °C). This range reflects factory binning to ensure consistent brightness across production lots, supporting uniform appearance in multi-LED assemblies.
What is the dominant wavelength specification for TLHR6405?
The TLHR6405 has a dominant wavelength range of 612–630 nm, placing its red emission within the standard visible red band optimized for human visual detection and color-coded status recognition. Peak wavelength is specified at 635 nm.
Does TLHR6405 support pulsed operation, and what is its surge current rating?
Yes, TLHR6405 supports pulsed operation with a surge forward current rating of 1 A for pulse widths ≤10 μs. This allows brief overdrive for enhanced visibility during transient alerts while maintaining long-term reliability under DC bias.
What is the viewing angle of TLHR6405, and how does it affect panel design?
The TLHR6405 has an angle of half intensity of ±30°, meaning luminous intensity drops to 50% at 30° off-axis. This wide viewing cone simplifies front-panel layout by reducing alignment sensitivity and enabling visibility across broad operator angles without secondary optics.
Is TLHR6405 RoHS-compliant and halogen-free?
Yes, TLHR6405 is RoHS-compliant and halogen-free, meeting environmental standards per Vishay document #99912. Material categorization documentation is available at www.vishay.com/doc?99912, supporting regulatory compliance for global electronics manufacturing.
