Product details
Overview
TLCY6800 from Vishay Semiconductors is a yellow ultrabright AlInGaP-on-GaAs LED in a 5 mm clear, non-diffused, untinted package with ±4° viewing angle, 5750–25,000 mcd luminous intensity at 50 mA, and 585–597 nm dominant wavelength - used in high-visibility automotive CHMSL and outdoor LED panels.
For engineers reviewing the TLCY6800 datasheet, TLCY6800 pinout, TLCY6800 application, or TLCY6800 equivalent, key selection criteria include luminous intensity binning (LL group), forward voltage range (2.1–2.7 V), junction temperature rating (125 °C), ESD withstand (2 kV), and narrow-angle optical performance for directional signaling.
Technical Context
The TLCY6800 employs AlInGaP semiconductor technology on GaAs substrate to deliver high-efficiency yellow emission with tight spectral control (Δλ = 17 nm at 50% Irel max) and low thermal drift (TCλd = 0.1 nm/K). Its parabolic lens geometry enables ±4° half-intensity angle and optimized light extraction.
Rated for continuous DC forward current up to 50 mA (Tamb ≤ 85 °C), it supports surge currents of 1 A (tp ≤ 10 μs) and operates across –40 to +100 °C ambient. Thermal resistance RthJA is 300 K/W, limiting power dissipation to 135 mW at Tamb = 25 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 5750–25,000 mcd at 50 mA - defines minimum/typical brightness per bin (LL group); critical for visibility compliance in traffic and automotive indicators |
| Dominant wavelength | 585–597 nm - ensures consistent yellow chromaticity meeting CIE 1931 color space requirements for signaling applications |
| Forward voltage | 2.1–2.7 V at 50 mA - determines driver voltage headroom and series-resistor sizing in constant-current circuits |
| Viewing angle | ±4° half-intensity - provides highly directional beam for focused illumination without secondary optics |
| Junction temperature | Up to 125 °C - enables operation in under-hood or enclosed high-temperature environments without derating |
| ESD withstand | 2 kV per JESD22-A114-B - reduces need for external protection in board-level ESD-prone assemblies |
| Thermal resistance | 300 K/W - informs heatsinking requirements when operating near maximum power dissipation (135 mW) |
Pinout & Package
Package: 5 mm radial-leaded, clear untinted non-diffused plastic housing with parabolic lens; lead spacing 2.54 mm (0.1"), body diameter Ø5.0 ±0.15 mm, overall height 8.7 ±0.3 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connected to constant-current source or series resistor; polarity must be observed to avoid reverse breakdown (VR = 5 V max) |
| Cathode (shorter lead) | Negative terminal | Typically tied to ground or current-sink driver; reverse conduction permitted only briefly per datasheet note (1) |
Key Features
| Feature | Design Value |
|---|---|
| AlInGaP-on-GaAs die technology | Delivers high radiant efficiency and stable yellow output with minimal wavelength shift over temperature (TCλd = 0.1 nm/K) |
| Untinted non-diffused lens | Preserves peak luminance and enables precise beam collimation for long-distance visibility in stop lights and signage |
| Luminous intensity binning (LL group) | Guarantees 5750–11,500 mcd consistency within each bag - eliminates post-assembly brightness sorting in production |
| High junction temperature rating | 125 °C Tj allows direct mounting on thermally stressed PCBs (e.g., automotive instrument clusters) without active cooling |
| ESD robustness | 2 kV HBM rating reduces risk of field failure during handling and assembly without added TVS protection |
Applications
| Automotive CHMSL | Traffic Signal Modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TLHY5900 | Same 5 mm package, but wider viewing angle (±15°); lower luminous intensity (1200–6000 mcd); 588–592 nm dominant wavelength | Better suited for wide-angle panel backlighting than directional signaling | Select TLCY6800 when narrow beam and high intensity are required; TLHY5900 when broader coverage is acceptable |
| Lumex SSL-LX5093ID | 5 mm yellow LED with ±10° viewing angle, 10,000–20,000 mcd at 20 mA, VF = 2.0–2.4 V; no specified Tj rating above 100 °C | Rated for lower drive current and ambient temperature; not qualified for automotive CHMSL duty cycle | Choose TLCY6800 for high-temperature, high-intensity, automotive-grade use; SSL-LX5093ID for cost-sensitive general-purpose indicators |
Compared with TLHY5900 and SSL-LX5093ID, the TLCY6800 delivers superior directionality and thermal resilience - enabling reliable operation in sealed automotive housings and outdoor signal heads where heat buildup and optical precision are critical design constraints.

FAQ
What is the maximum continuous forward current for TLCY6800?
The TLCY6800 is rated for 50 mA DC forward current at ambient temperatures ≤ 85 °C. Exceeding this requires derating per Fig. 1 in the datasheet; at 100 °C ambient, maximum allowable current drops to ~30 mA to maintain Tj ≤ 125 °C. The TLCY6800 must not be operated beyond its absolute maximum ratings to ensure long-term reliability and lumen maintenance.
Does TLCY6800 have a defined pin-compatible replacement within Vishay's portfolio?
No pin-compatible replacement is documented for the TLCY6800. While other 5 mm Vishay LEDs like TLHY5900 share the same package outline and lead spacing, differences in viewing angle, intensity binning, and thermal specifications preclude drop-in substitution. System-level validation is required before substituting any alternative part for the TLCY6800.
How is luminous intensity binned for TLCY6800, and what does "LL group" mean?
The TLCY6800 is shipped in standardized luminous intensity bins; "LL group" corresponds to 5750–11,500 mcd at 50 mA. Each packaging unit contains LEDs from only one bin - no mixing - ensuring consistent brightness across production batches. This binning eliminates post-manufacture sorting for applications requiring uniform visual output, such as multi-LED traffic signal arrays.
Can TLCY6800 be driven directly from a microcontroller GPIO pin?
Yes, the TLCY6800 can be driven directly from a 3.3 V or 5 V microcontroller GPIO if limited to ≤5 mA average current using a series resistor - but this yields suboptimal brightness. For full-rated 50 mA operation, a constant-current driver or transistor-switched circuit is required. The TLCY6800 forward voltage (2.1–2.7 V) must be accounted for in resistor calculation to avoid exceeding GPIO current limits.
What is the significance of the ±4° viewing angle specification for TLCY6800?
The ±4° half-intensity viewing angle means luminous intensity drops to 50% of peak value at 4° off-axis - resulting in a tightly collimated beam ideal for directional applications like CHMSL and traffic signals. This narrow angle minimizes light spill, improves contrast in bright ambient conditions, and allows precise optical targeting without secondary lenses or reflectors - a key differentiator versus standard 20–30° indicator LEDs.
