Product details
Overview
TLHK5100 from Vishay Semiconductors is a clear, non-diffused 5 mm red LED optimized for outdoor applications including traffic signals and CHMSL. It features AlInGaP-on-GaAs technology, 630 nm typical dominant wavelength, ±9° viewing angle, 1400 mcd typical luminous intensity at 20 mA, and 2.6 V max forward voltage.
For engineers reviewing the TLHK5100 datasheet, TLHK5100 pinout, TLHK5100 application, or TLHK5100 equivalent, key selection criteria include outdoor visibility performance, narrow-angle beam control, thermal robustness to +100°C ambient, and compatibility with standard 5 mm through-hole PCB layouts.
Technical Context
The TLHK5100 employs AlInGaP-on-GaAs heterostructure technology to deliver high-efficiency red emission with tight spectral control (626–639 nm dominant wavelength). Its untinted, non-diffused lens and ±9° half-intensity angle enable focused light output ideal for long-distance signaling.
Rated for DC forward current up to 30 mA and junction temperature up to 100°C, the device maintains stable luminous intensity across -40°C to +100°C operating range. Thermal resistance junction-to-ambient is 350 K/W, supporting reliable operation in unheatsinked outdoor enclosures.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TLHR5100 | Diffused lens, ±25° viewing angle, 800 mcd typ. - broader beam, lower peak intensity | Better suited for wide-angle panel indicators; not recommended for directional signaling | Select TLHR5100 only when uniform surface illumination-not focused beam-is required |
| Lumex SSL-LX5093ID | 5 mm red, ±10° viewing angle, 1200 mcd typ., GaAsP technology - lower efficiency, higher VF drift with temperature | Lower thermal stability limits use in high-ambient automotive or outdoor enclosures | Choose SSL-LX5093ID only for cost-sensitive indoor instrumentation where ambient ≤65°C |
Compared with TLHR5100 and SSL-LX5093ID, the TLHK5100 delivers superior directionality and outdoor thermal resilience-critical for traffic and CHMSL applications where beam control and high-temperature reliability are non-negotiable.

FAQ
What is the maximum continuous forward current rating for the TLHK5100?
The TLHK5100 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤65°C. Exceeding this value risks accelerated lumen depreciation and junction overheating beyond the 100°C limit. Derating is required above 65°C ambient per Fig. 1 in the datasheet. Always verify thermal design using the 350 K/W RthJA value when operating TLHK5100 in enclosed or high-temperature environments.
Does the TLHK5100 meet RoHS and halogen-free compliance requirements?
Yes, the TLHK5100 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay specification. Environmental symbols-including Pb-free and halogen-free markings-are printed on the product label per documentation in www.vishay.com/doc?99912. Full compliance data is available in the material declaration for TLHK5100 on the Vishay website.
What is the significance of the ±9° angle of half intensity for the TLHK5100?
The ±9° angle of half intensity defines the angular cone within which luminous intensity remains ≥50% of its peak axial value. For the TLHK5100, this narrow beam enables precise optical targeting in traffic signals and CHMSL without secondary lenses. It directly supports photometric compliance with SAE J578 and EN 12367 by ensuring adequate candela at specified viewing angles.
Can the TLHK5100 be used in pulsed operation, and what are the surge limits?
Yes, the TLHK5100 supports pulsed operation with a surge forward current rating of 1 A for pulse widths ≤10 μs. This capability allows brief overdrive for strobe or flash applications, provided duty cycle and average power remain within the 100 mW dissipation limit. Pulse testing must follow the 25 ms duration condition specified for luminous intensity measurement to ensure repeatable photometric results for TLHK5100.
How is luminous intensity binned for the TLHK5100, and what brightness groups are shipped?
The TLHK5100 is binned into luminous intensity groups (e.g., AA: 320–640 mcd, DD: 750–1500 mcd) per the datasheet table. Only one brightness group is shipped per bag-no mixing occurs. Single-group orders are not supported to ensure supply continuity; standard orders receive mixed-bag shipments covering the full Z–HH range. Brightness binning is verified at 20 mA, 25°C, with 25 ms pulse width.
