Product details
Overview
TLCS5100 from Vishay Semiconductors is a super red, ultrabright 5 mm LED with untinted non-diffused lens, AlInGaP-on-GaAs technology, 2400–7500 mcd luminous intensity at 50 mA, 626–638 nm dominant wavelength, and ±9° viewing angle - deployed in high-visibility automotive stop lights and instrumentation indicators.
For engineers reviewing the TLCS5100 datasheet, TLCS5100 pinout, TLCS5100 application, or TLCS5100 equivalent, this page delivers verified optical specs, thermal limits, binning classification, absolute maximum ratings, and real-world use context for front-panel, CHMSL, and outdoor panel lighting design.
Technical Context
The TLCS5100 uses AlInGaP-on-GaAs die architecture to achieve high radiant efficiency in the super red spectrum (626–638 nm), with junction temperature rated up to 125 °C and thermal resistance of 300 K/W. Its ±9° half-intensity angle and untinted lens enable tight beam control without diffusion loss.
It operates at 50 mA DC forward current with 2.1–2.7 V forward voltage, supports reverse voltage up to 5 V, and exhibits luminous intensity binned per packing unit (IVmax/IVmin ≤ 2.0). ESD withstand is rated at 2 kV per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 2400–7500 mcd at 50 mA - enables high-brightness indicator operation without external optics or current boosting. |
| Dominant wavelength | 626–638 nm - falls within super red spectral band optimized for human photopic response and regulatory compliance in vehicle lighting. |
| Viewing angle | ±9° half-intensity - provides narrow, directional light output ideal for focused signage and discrete panel indicators. |
| Forward voltage | 2.1–2.7 V at 50 mA - compatible with standard 3.3 V and 5 V logic-level driver circuits without series resistor overdesign. |
| Junction temperature | Up to 125 °C - supports operation in under-hood automotive environments and sealed outdoor enclosures. |
| ESD rating | 2 kV HBM - reduces risk of handling damage during manual assembly or low-voltage test fixture integration. |
| Thermal resistance | 300 K/W - defines thermal path limitation; requires PCB copper area or heatsinking for sustained 50 mA operation above 70 °C ambient. |
Pinout & Package
TLCS5100 is a 2-terminal through-hole LED in standard 5 mm round package (Ø5.0 ±0.15 mm body, 12.9 ±0.3 mm total length) with axial leads. Cathode identified by flat edge on lens housing and shorter lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current source or driver output; polarity reversal risks irreversible damage beyond 5 V reverse bias. |
| Cathode (shorter lead, flat side) | Negative terminal | Reference node for current return; must be tied to ground or sink driver; identifies orientation during manual placement. |
Key Features
| Feature | Design Value |
|---|---|
| Untinted non-diffused lens | Preserves peak luminance density and angular precision - avoids intensity loss from internal scattering in indicator applications requiring sharp cutoff. |
| AlInGaP-on-GaAs die | Delivers superior quantum efficiency in 620–640 nm range versus older GaAsP - enables higher mcd/W at 50 mA without thermal runaway. |
| Luminous intensity binning | Single brightness group per bag (e.g., HH = 2400–4800 mcd) - eliminates post-assembly sorting and ensures consistent visual match across panels. |
| High-temperature operation | Rated for Tj = 125 °C - allows direct mounting on thermally stressed PCBs in engine bay or industrial control cabinets without derating. |
| ESD robustness | 2 kV HBM rating - reduces need for external TVS protection in low-speed indicator circuits, lowering BOM count. |
Applications
| Automotive CHMSL | Instrumentation Indicators |
|---|---|
Use Scenario: Central high-mounted stop light on passenger vehicles requiring SAE J1393-compliant red emission and visibility at >100 m. IC Role / Device Role / Timing Role: Discrete light-emitting element - no timing or control function; driven by constant-current switch-mode or linear LED driver. Use Value: 626–638 nm dominant wavelength meets spectral purity requirements; ±9° beam minimizes stray light into adjacent optics while delivering ≥7500 mcd at 50 mA for daylight legibility. |
Use Scenario: Front-panel status indicator on industrial HMIs, medical devices, or test equipment where color-coded feedback must remain visible under ambient illumination. IC Role / Device Role / Timing Role: Visual signaling component - electrically passive emitter; driven by microcontroller GPIO or dedicated LED driver IC. Use Value: Untinted lens preserves luminance density; 2400–7500 mcd range allows brightness tuning via series resistor or PWM without changing part number or layout. |
| Outdoor LED Panels | Light Guide Integration |
Use Scenario: Pixel element in monochrome outdoor message signs exposed to UV, humidity, and thermal cycling from −40 to +100 °C ambient. IC Role / Device Role / Timing Role: Primary light source - mounted directly on FR4 or metal-core PCB; no embedded intelligence or interface. Use Value: 125 °C junction rating and −40 to +100 °C operating range ensure reliability without active cooling; AlInGaP die resists UV-induced lumen depreciation better than phosphor-converted alternatives. |
Use Scenario: Edge-lit light guide in control dashboards or appliance interfaces requiring uniform red illumination across translucent symbols. IC Role / Device Role / Timing Role: Point-source input coupler - positioned at light guide perimeter; optical coupling efficiency depends on collimation and alignment. Use Value: ±9° viewing angle matches typical light guide acceptance angles; non-diffused lens maximizes coupling efficiency into acrylic or polycarbonate guides without secondary optics. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TLHR5100 | Same 5 mm package and AlInGaP-on-GaAs die, but red (611–622 nm) with higher typical intensity (11,000 mcd) and wider spectral bandwidth (18 nm vs. 20 nm). | Better suited for general-purpose red indication where spectral purity is less critical than raw brightness; not compliant with CHMSL red wavelength limits. | Select TLHR5100 only if dominant wavelength tolerance >622 nm is acceptable and higher intensity justifies potential color mismatch in multi-LED arrays. |
| OSRAM LHU6BR | 5 mm T-1¾ package, 625–635 nm, 3000–9000 mcd at 50 mA, ±10° viewing angle, 2.0–2.6 V VF - similar optical performance but different mechanical footprint and thermal resistance (320 K/W). | Compatible with same PCB pad layout only if revised for 2.54 mm lead spacing and 5.1 mm body diameter; slightly wider beam may require light guide redesign. | Choose LHU6BR when sourcing diversification is required and minor mechanical rework is acceptable; verify thermal margin given higher RthJA. |
Compared with TLCS5100, TLHR5100 offers higher intensity but narrower spectral compliance, while LHU6BR provides comparable photometry with different mechanical fit and thermal behavior - neither is pin-compatible, and both require validation of optical alignment and thermal management in target assemblies.

FAQ
What is the maximum continuous forward current for TLCS5100?
The TLCS5100 is rated for 50 mA DC forward current at ambient temperatures ≤85 °C. Exceeding this value without thermal derating risks accelerated lumen depreciation and junction temperature exceeding 125 °C. Pulse operation up to 1 A is allowed only for ≤10 μs duration, as specified in the absolute maximum ratings table of the Vishay datasheet 81346.
Does TLCS5100 have a built-in current-limiting resistor?
No, TLCS5100 is a bare LED die in a 5 mm package with no integrated current-limiting resistor. It requires an external series resistor or constant-current driver to regulate forward current at 50 mA. The forward voltage range of 2.1–2.7 V at 50 mA must be used to calculate appropriate resistor value based on supply voltage and thermal conditions.
Can TLCS5100 be used in reverse-bias configurations?
The TLCS5100 datasheet notes that short-term reverse driving is suitable for specific applications, but its absolute maximum reverse voltage is only 5 V. Sustained reverse bias or voltage spikes beyond this limit will cause permanent degradation. It is not designed as a bidirectional device and should be operated strictly in forward conduction mode for reliable service life.
How is luminous intensity binned for TLCS5100 shipments?
TLCS5100 is shipped in single brightness groups per bag (e.g., HH = 2400–4800 mcd), with IVmax/IVmin ≤ 2.0 within each unit. Vishay does not ship mixed bins - each packing unit contains only one luminous intensity category, ensuring visual consistency across assembled units without post-production sorting.
What is the lead finish and RoHS status of TLCS5100?
TLCS5100 features lead-free (Pb-free) termination finish and complies with RoHS Directive 2011/65/EU and REACH regulations. Environmental symbols including RoHS and halogen-free markings appear on the product label per Vishay documentation. Full compliance data is available in Vishay's material declaration document 99912.
