Product details
Overview
TLHY5405 from Vishay Semiconductors is a yellow high-efficiency LED in a 5 mm tinted diffused T-1¾ plastic package, with dominant wavelength 581–594 nm, luminous intensity 6.3–14 mcd at 10 mA, and ±30° viewing angle. It serves as a status indicator or legend light in industrial control panels requiring high on-off contrast and uniform color appearance.
For engineers reviewing the TLHY5405 datasheet, TLHY5405 pinout, TLHY5405 application, or TLHY5405 equivalent, this page delivers verified optical, electrical, and packaging data - including forward voltage (2.4 V typ. @ 20 mA), reverse voltage rating (6 V), junction temperature limit (100 °C), and luminous intensity binning (Q group) - to support reliable visual interface design and BOM validation.
Technical Context
The TLHY5405 uses GaAsP-on-GaP semiconductor technology optimized for visible yellow emission, with peak wavelength at 585 nm and narrow dominant wavelength binning (six groups: 1–6) enabling consistent color matching across assemblies. Its 5 mm diffused lens provides wide angular distribution and high contrast under ambient lighting.
Rated for DC and pulsed operation up to 1 A surge current (tp ≤ 10 μs), it supports both steady-state panel indicators and duty-cycled backlighting. Thermal resistance is 350 K/W, allowing operation from –40 °C to +100 °C ambient with derated forward current above 65 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Yellow (dominant wavelength 581–594 nm, peak 585 nm) |
| Luminous intensity | 6.3–14 mcd at 10 mA (Q bin group; ensures brightness uniformity within packing unit) |
| Forward voltage | 2.4 V typical at 20 mA (enables direct drive from 3.3 V or 5 V logic with series resistor) |
| Viewing angle | ±30° half-intensity (wide dispersion suitable for front-panel visibility across 60° cone) |
| Absolute max IF | 30 mA continuous (derates linearly above 65 °C ambient; supports long-life operation) |
| Reverse voltage | 6 V (limits need for external protection diode in low-voltage DC applications) |
| Junction temp | 100 °C max (defines thermal design margin for PCB copper area and airflow requirements) |
Pinout & Package
TLHY5405 is housed in a standard 5 mm (T-1¾) radial-leaded plastic package with cathode-indicating flat edge and internal anode/cathode bond wires. Leads are tin-plated copper, compatible with reflow and wave soldering per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Connects to current-limiting resistor and supply rail; polarity must be observed to avoid damage |
| Cathode (shorter lead / flat side) | Negative terminal | Common return path; marked by flat edge on lens housing and shorter lead length |
Key Features
| Feature | Design Value |
|---|---|
| Wide viewing angle (±30°) | Enables clear visibility across broad operator angles without mechanical aiming |
| Luminous intensity binning (Q group) | Guarantees 6.3–12.5 mcd consistency within each bag - critical for uniform panel appearance |
| Wavelength binning (6 groups) | Ensures tight yellow hue match across multiple units - avoids visible color shift in multi-LED arrays |
| DC and high peak current capable | Supports 30 mA continuous or 1 A transient pulses (10 μs), enabling PWM dimming and strobe use |
| Tinted diffused lens | Provides soft, glare-free illumination with high on/off contrast under ambient light |
Applications
| Status lights | Off / on indicator |
|---|---|
Use Scenario: Visual confirmation of system power-up, fault state, or communication activity on industrial HMIs and PLC modules. IC Role / Device Role / Timing Role: Discrete light-emitting component providing human-readable state feedback. Use Value: High on-off contrast and ±30° viewing angle ensure legibility from multiple operator positions without backlighting. |
Use Scenario: Binary indication on test equipment front panels, medical device controls, or lab instrumentation. IC Role / Device Role / Timing Role: Passive optical output element driven directly by microcontroller GPIO or discrete transistor switch. Use Value: Q-group luminous intensity binning guarantees consistent brightness across all units in production batches. |
| Legend light | Background illumination |
Use Scenario: Illuminating engraved or printed labels on control panels, switchgear, or safety enclosures. IC Role / Device Role / Timing Role: Surface-mount or through-hole indicator mounted behind translucent legend overlay. Use Value: Tinted diffused lens delivers even, non-hotspot illumination ideal for text/graphics readability. |
Use Scenario: Edge-lit bezels or low-level ambient lighting in diagnostic tools and portable instruments. IC Role / Device Role / Timing Role: Low-power visible emitter used in constant-current or PWM-driven backlight circuits. Use Value: 2.4 V typical forward voltage simplifies biasing from common 3.3 V rails with minimal resistor dissipation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TLHY5401 | Luminous intensity 4–12 mcd (N bin); lower brightness than TLHY5405's Q bin | Suitable where moderate brightness suffices and tighter intensity matching is not required | Select TLHY5401 when cost sensitivity outweighs need for highest luminance uniformity |
| ROHM SML-010YTT86R | Surface-mount 0805 package; 570–590 nm dominant wavelength; 12–18 mcd @ 20 mA | Requires PCB redesign for SMT vs. TLHY5405's through-hole 5 mm package | Choose SML-010YTT86R only when board space constraints mandate SMT and higher intensity is acceptable |
Compared with TLHY5401 and SML-010YTT86R, TLHY5405 delivers optimal balance of through-hole manufacturability, Q-bin intensity uniformity, and 581–594 nm yellow spectral fidelity - making it preferred for legacy panel designs requiring field-serviceable replacement and consistent visual identity.

FAQ
What is the dominant wavelength range of TLHY5405?
The TLHY5405 has a dominant wavelength range of 581–594 nm, binned into six color groups (1–6) to ensure consistent yellow hue across production lots. This specification is measured at 10 mA forward current and enables precise color matching in multi-LED interfaces where visual uniformity is critical.
What luminous intensity bin does TLHY5405 belong to?
TLHY5405 is categorized in the Q luminous intensity bin, specifying 6.3–12.5 mcd at 10 mA. Each packaging unit contains LEDs from only one intensity bin, ensuring brightness consistency without mixing - vital for panel-level visual coherence.
Can TLHY5405 be driven directly from a 3.3 V microcontroller GPIO?
No - TLHY5405 requires a series current-limiting resistor when driven from 3.3 V, as its typical forward voltage is 2.4 V at 20 mA. With 3.3 V supply, a ~47 Ω resistor sets nominal current near 20 mA; always verify thermal derating above 65 °C ambient.
What is the maximum continuous forward current for TLHY5405?
The absolute maximum DC forward current for TLHY5405 is 30 mA at ambient temperatures ≤65 °C. Above 65 °C, current must be linearly derated to maintain junction temperature ≤100 °C, with full derating to 0 mA at 100 °C ambient.
Does TLHY5405 have a built-in current-limiting resistor?
No, TLHY5405 is a bare LED die in a 5 mm package with no integrated resistor. External current control - via series resistor, constant-current driver, or active circuit - is mandatory to prevent thermal runaway and ensure rated lifetime.
