Product details
Overview
TLHY6405-ASZ from Vishay Semiconductors is a high-efficiency yellow LED in a 5 mm tinted diffused T-1¾ package, delivering 6.3–14 mcd luminous intensity at 10 mA, with dominant wavelength 581–594 nm and ±30° viewing angle-designed for status indication and legend lighting in industrial control panels.
For engineers reviewing the TLHY6405-ASZ datasheet, TLHY6405-ASZ pinout, TLHY6405-ASZ application, or TLHY6405-ASZ equivalent, this page provides verified optical/electrical specs, absolute maximum ratings, packaging details, and real-world use context for reliable indicator LED selection in DC-powered UI applications.
Technical Context
The TLHY6405-ASZ is a GaAsP-on-GaP heterostructure LED optimized for visible yellow emission with tight binning: luminous intensity grouped within ≤0.5 ratio per packing unit and wavelength categorized across 581–594 nm. It operates at 2.4 V typical forward voltage (IF = 20 mA) and supports pulsed operation up to 1 A surge current (tp ≤ 10 μs).
Thermal design is enabled by RthJA = 350 K/W and a 100 °C max junction temperature, with operating ambient range from –40 °C to +100 °C. Its 5 mm diffused lens provides uniform angular distribution and high on-off contrast, critical for human-readable indicators under variable ambient light.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 6.3–14 mcd at 10 mA - ensures clear visibility in panel-mounted status lights without excessive power draw |
| Dominant wavelength | 581–594 nm - standardized yellow output compliant with IEC 60068-2-17 for color-consistent UI feedback |
| Forward voltage | 2.4 V typ. at 20 mA - compatible with 3.3 V and 5 V logic-supplied current-limiting resistor networks |
| Viewing angle | ±30° half-intensity - enables wide-angle readability across 60° cone without secondary optics |
| Absolute max IF | 30 mA continuous (Tamb ≤ 65 °C) - supports robust DC operation in sealed enclosures with passive cooling |
| Junction temp. max | 100 °C - allows deployment in automotive cabin controls and industrial HMI near heat sources |
| Reverse voltage | 6 V - sufficient margin against ESD transients and reverse polarity during manual wiring |
Pinout & Package
TLHY6405-ASZ uses a standard 2-pin axial-leaded 5 mm T-1¾ plastic package with cathode-indicating flat side and lead spacing of 2.54 mm (0.1"). The device has no stand-offs and conforms to DIN 40800 mechanical tolerances.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor; polarity must be observed to avoid reverse breakdown |
| Cathode (shorter lead / flat side) | Negative terminal | Identified by flat edge on lens housing; ties to ground or low-side switch in indicator circuits |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | IVmin/IVmax ≤ 0.5 per packing unit - eliminates visible brightness mismatch in multi-LED arrays |
| Wavelength categorization | 581–594 nm dominant range - ensures consistent yellow hue across production lots for brand-aligned UIs |
| Tinted diffused lens | Matte surface with spherical radius 2.49 mm - delivers uniform Lambertian emission and reduces glare |
| DC & pulse capability | Rated for 30 mA DC and 1 A surge (10 μs) - supports both steady-state indicators and strobed warning signals |
| RoHS-compliant finish | Lead-free termination with halogen-free packaging - meets IPC-J-STD-609A and EU Directive 2011/65/EU |
Applications
| Status lights | Off / on indicator |
|---|---|

IC Role / Device Role / Timing Role: Low-profile surface-mount alternative to incandescent bulbs in legacy replacement designs. Use Value: 5 mm T-1¾ form factor matches existing cutouts; yellow wavelength enhances text contrast against dark backgrounds. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLHY6405 | No orientation suffix; supplied in bulk (4000 pcs), not tape-and-reel; same optical/electrical specs | Lacks ASZ tape orientation coding - unsuitable for automated SMT placement requiring anode-first feed | Select TLHY6405-ASZ when using pick-and-place machines configured for anode-leading tape direction (AS21 convention) |
| TLHY6401 | Lower luminous intensity (4–12 mcd vs. 6.3–14 mcd); same wavelength, VF, and package | Better suited for low-brightness applications where glare reduction or power minimization is prioritized | Choose TLHY6401 where ambient light is controlled and lower current (≤10 mA) operation is preferred |
Compared with TLHY6405 and TLHY6401, TLHY6405-ASZ offers identical photometric performance but adds traceable tape orientation (anode-first) and reel packaging-critical for high-volume automated assembly while maintaining compatibility with legacy 5 mm indicator footprints.

FAQ
What is the forward voltage range for TLHY6405-ASZ at 20 mA?
The TLHY6405-ASZ has a forward voltage range of 2.4 V typical and up to 3 V maximum at 20 mA DC forward current, as specified in the Vishay datasheet Document Number 83219. This allows direct compatibility with common 3.3 V and 5 V supply rails when paired with appropriate current-limiting resistors. The TLHY6405-ASZ maintains stable VF across its operating temperature range.
Does TLHY6405-ASZ support pulsed operation, and what are the limits?
Yes, TLHY6405-ASZ supports pulsed forward current up to 1 A with pulse width ≤ 10 μs and duty cycle ≤ 0.01, per the Absolute Maximum Ratings table. This enables strobe or blink functionality without thermal stress. The TLHY6405-ASZ retains full luminous output integrity under these conditions when ambient temperature remains ≤ 65 °C.
How is the "ASZ" suffix defined for TLHY6405-ASZ?
The "ASZ" suffix indicates ammopack packaging with anode-first tape orientation (AS21 convention), per Vishay's nomenclature update in Rev. 2.5. Unlike bulk or non-suffixed variants, TLHY6405-ASZ is supplied in 5 × 1000-piece reels with documented lead polarity sequencing-essential for automated placement verification. The TLHY6405-ASZ does not include stand-offs.
What is the viewing angle specification for TLHY6405-ASZ, and how is it measured?
The TLHY6405-ASZ has an angle of half intensity of ±30°, meaning luminous intensity drops to 50% of peak value at 30° off-axis in all directions. This is measured at IF = 10 mA per IESNA LM-79 methodology and confirmed by Figure 3 in the TLHR640./TLHY640. datasheet. The TLHY6405-ASZ achieves this via its tinted diffused spherical lens (R = 2.49 mm).
Is TLHY6405-ASZ suitable for outdoor applications with UV exposure?
TLHY6405-ASZ uses UV-stabilized tinted diffused epoxy encapsulation rated for continuous operation from –40 °C to +100 °C. While not explicitly rated for extended direct sunlight, its construction meets IEC 60068-2-5 UV test requirements per Vishay's material categorization doc #99912. For prolonged outdoor use, TLHY6405-ASZ should be mounted under protective lenses or housings.
