Product details
Overview
TLHB5401 from Vishay Telefunken is a high-efficiency blue light-emitting diode (LED) using GaN-on-SiC technology in a standard 5 mm tinted diffused T-1 3/4 package, with dominant wavelength 466 nm, luminous intensity 10–32 mcd at 20 mA, and ±30° viewing angle-designed for status indication and legend lighting in industrial control panels.
For engineers reviewing the TLHB5401 datasheet, TLHB5401 pinout, TLHB5401 application, or TLHB5401 equivalent, key selection criteria include luminous intensity binning, ESD Class 1 rating, thermal resistance (350 K/W), forward voltage (3.9–4.5 V), and operating temperature range (–40 to +100 °C).
Technical Context
This LED employs gallium nitride (GaN) epitaxially grown on silicon carbide (SiC) substrate, enabling higher quantum efficiency and improved thermal stability versus earlier SiC-only devices. It replaces legacy TLHB540-series variants with enhanced optical output and tighter spectral control.
The device operates as a low-power, visible-light emitter with DC forward current rated up to 20 mA (continuous) and surge capability of 100 mA for ≤10 s. Its 5 mm plastic package features mechanical tolerances suitable for automated insertion and consistent optical diffusion.

Equivalent & Alternatives
The following parts are listed as comparable options for similar blue LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kingbright APL-5012SURK | AlInGaP red-orange emitter (625 nm), 15–35 mcd, same 5 mm T-1 3/4 package and 20 mA rating | Not spectrally equivalent; used where color-coding requires red/orange instead of blue | Select when system-level color scheme mandates non-blue status coding or when GaN reliability concerns outweigh spectral match |
| Vishay TLHB5400 | Same GaN-on-SiC die, lower luminous intensity bin (6.3–15 mcd), identical package and electrical specs | Substitutable where lower brightness suffices and cost optimization is prioritized | Choose TLHB5400 if panel layout permits higher LED density or ambient light levels are lower than 500 lux |
Compared with TLHB5401, APL-5012SURK offers different chromaticity but identical mechanical fit, while TLHB5400 shares full compatibility except for reduced luminous output-making TLHB5401 optimal for high-visibility blue indication where brightness headroom is critical.

FAQ
What is the dominant wavelength of TLHB5401 and why does it matter for indicator design?
The TLHB5401 has a dominant wavelength of 466 nm, placing its output in the vivid blue region of the visible spectrum. This value matters because it ensures high perceptual contrast against common panel backgrounds and meets international standards for status-color coding. The TLHB5401's narrow peak at 428 nm and tight binning support consistent visual signaling across batches-critical when multiple TLHB5401 units are used in a single HMI.
Can TLHB5401 be driven directly from a 5 V microcontroller GPIO pin?
No-TLHB5401 requires current limiting due to its forward voltage range of 3.9–4.5 V and maximum rated forward current of 20 mA. Driving it directly from a 5 V GPIO risks exceeding IF and causing premature degradation. A series resistor (e.g., 100 Ω for ~20 mA at 5 V) or constant-current driver is required. The TLHB5401's thermal resistance (350 K/W) also necessitates attention to PCB copper area for heat dissipation in sustained operation.
How does the luminous intensity binning of TLHB5401 benefit panel assembly?
TLHB5401 is categorized into luminous intensity groups (10–32 mcd at 20 mA), allowing manufacturers to select matched bins for uniform appearance across multi-LED interfaces. This binning eliminates visible brightness variation between adjacent TLHB5401 units on control panels-essential for professional-grade HMIs where inconsistent lighting undermines perceived product quality and usability.
Is TLHB5401 suitable for outdoor applications exposed to temperature extremes?
Yes-TLHB5401 is rated for operation from –40 to +100 °C ambient temperature and storage across the same range. Its GaN-on-SiC construction provides superior thermal stability versus older LED technologies. However, optical lens material (tinted diffused plastic) must be verified for UV resistance if deployed in direct sunlight; the TLHB5401 itself remains functional within its specified thermal envelope under those conditions.
What does ESD Class 1 mean for handling TLHB5401 during PCB assembly?
ESD Class 1 indicates that TLHB5401 can be damaged by discharges as low as 250 V, requiring strict electrostatic control: grounded workstations, ionized air, wrist straps, and shielded packaging. Unlike higher-class LEDs, TLHB5401 lacks integrated protection diodes-so transient events during pick-and-place or hand-soldering may cause latent or immediate failure. This classification applies specifically to the TLHB5401 and informs ESD protocol decisions in SMT lines.
