Product details
Overview
TLHG6420 from Vishay Semiconductors is a green 5 mm tinted diffused LED using AlInGaP-on-GaAs technology, with dominant wavelength 562–575 nm, luminous intensity 6.3–20 mcd at 10 mA, forward voltage 2.1–2.4 V at 20 mA, and ±25° viewing angle - deployed in status indicators and legend lighting where high on-off contrast and uniform appearance are required.
For engineers reviewing the TLHG6420 datasheet, TLHG6420 pinout, TLHG6420 application, or TLHG6420 equivalent, this page delivers verified optical/electrical specs, package dimensions, binning classification, absolute maximum ratings, and direct alternatives for industrial indicator design and BOM continuity planning.
Technical Context
The TLHG6420 is a through-hole, stand-off-free 5 mm T-1¾ LED with anode/cathode leads terminating flush to the base - optimized for manual or wave-solder assembly without mechanical lift. Its AlInGaP-on-GaAs die delivers stable green emission with tight wavelength binning (groups 3–8) and luminous intensity grouping (Q–V).
Thermal resistance junction-to-solder point is 325 K/W; absolute max ratings include 25 mA DC forward current, 60 mA surge current (1/10 duty, 1 kHz), and operating ambient range of −40 °C to +85 °C - confirming suitability for non-hermetic industrial enclosures and panel-mounted indicator use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color & Technology | Green emission via AlInGaP-on-GaAs chip - ensures stable wavelength and high efficiency vs. older GaP devices |
| Dominant Wavelength | 562–575 nm (min–max) at 10 mA - falls within standard green visual recognition band for human-interface indicators |
| Luminous Intensity | 6.3–20 mcd at 10 mA - supports visibility under ambient light up to ~1000 lux without excessive power draw |
| Forward Voltage | 2.1–2.4 V at 20 mA - compatible with 3.3 V and 5 V logic-supplied current-limiting resistor designs |
| Viewing Angle | ±25° half-intensity - provides wide, uniform illumination for front-panel status lights with minimal hot-spotting |
| Junction Temp Limit | 100 °C max - sets thermal derating threshold for continuous operation in sealed enclosures |
| Reverse Voltage | 5 V max - defines minimum reverse protection needed in AC-coupled or bidirectional drive circuits |
Pinout & Package
TLHG6420 uses a standard 2-lead through-hole T-1¾ (5 mm) package with no stand-offs; anode and cathode leads extend directly from the base. Lead spacing is 2.54 mm (0.1"), body diameter 5.0 ± 0.2 mm, and total length ≤37.6 mm. Leads are tin-plated copper, RoHS-compliant, and rated for 260 °C soldering (5 s, 2 mm from body).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive terminal | Must be biased ≥2.1 V above cathode to achieve nominal light output; polarity-sensitive in series/parallel arrays |
| Cathode (shorter lead, flat side) | Negative terminal | Common return path; requires current-limiting resistor or constant-current driver to prevent thermal runaway |
Key Features
| Feature | Design Value |
|---|---|
| Standard T-1¾ package | Enables drop-in replacement in legacy 5 mm LED sockets and automated insertion tooling without retooling |
| Wide ±25° viewing angle | Reduces need for secondary optics in panel-mount applications - simplifies mechanical design and lowers bill-of-materials cost |
| Luminous intensity binning (Q–V) | Ensures consistent brightness across multiple units in multi-LED arrays - critical for uniform status bar or segmented display appearance |
| Wavelength binning (groups 3–8) | Maintains color-matching tolerance <3 nm between units - avoids visible hue variation in adjacent indicators |
| No stand-off construction | Allows flush mounting against PCB or bezel - eliminates air gap that causes glare or parallax in front-panel legends |
Applications
| Status Lights | Off / On Indicator |
|---|---|
Use Scenario: Front-panel power/status indication on industrial HMIs and DIN-rail mounted controllers. IC Role / Device Role / Timing Role: Visual state feedback device - driven by microcontroller GPIO or discrete transistor switch.

Use Value: No-stand-off package enables minimal PCB-to-legend distance (<1 mm), maximizing light coupling efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar green LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay TLHG5420-CSZ | Identical optical/electrical specs but includes 1 mm stand-off; longer lead length and elevated mounting position | Suitable where mechanical clearance is needed between PCB and front panel - e.g., thick bezels or stacked overlays | Select TLHG5420-CSZ only when physical stand-off is required; TLHG6420-CSZ is preferred for flush-mount or space-constrained layouts |
| ROHM SML-310MTT86 | Surface-mount 1206 package; 565–575 nm dominant wavelength; 12–24 mcd at 20 mA; VF = 2.0–2.4 V | Designed for reflow assembly and high-density PCBs - not mechanically interchangeable with through-hole TLHG6420 | Choose SML-310MTT86 for new SMT-only designs; TLHG6420 remains optimal for through-hole, repairable, or mixed-technology assemblies |
Compared with TLHG5420-CSZ and SML-310MTT86, TLHG6420 offers the unique combination of through-hole reliability, zero stand-off form factor, and factory-binned luminous intensity - making it the preferred choice for serviceable industrial panels where mechanical robustness and visual consistency are prioritized over miniaturization.

FAQ
What is the exact package type and lead configuration of TLHG6420?
The TLHG6420 uses a standard T-1¾ (5 mm) through-hole package with two axial leads and no stand-off. The anode lead is longer and marked by a flat edge on the lens housing; cathode is shorter. Lead pitch is 2.54 mm, body diameter 5.0 ± 0.2 mm, and total length ≤37.6 mm. This configuration supports wave soldering and manual insertion into 0.040"–0.062" PCB holes.
Does TLHG6420 require external current limiting, and what resistor value is typical at 5 V supply?
Yes, TLHG6420 requires external current limiting. At 5 V supply and target 20 mA forward current, a 140 Ω resistor is typical (R = (5 V − 2.25 V) / 0.02 A ≈ 137.5 Ω). Derating to 10 mA for extended life yields ~270 Ω. TLHG6420 has no internal current regulation - resistor selection must account for VF tolerance (2.1–2.4 V) and supply variance.
How are TLHG6420 units binned for luminous intensity and wavelength?
TLHG6420 units are factory-binned into luminous intensity groups Q–V (e.g., group R = 10–20 mcd) and wavelength groups 3–8 (e.g., group 6 = 568–571 nm). Each reel contains only one intensity group and one wavelength group - no mixing occurs. Single-group orders are not available to ensure supply continuity; binning data is encoded in the suffix (e.g., -CSZ indicates specific intensity/wavelength combination).
Can TLHG6420 be used in outdoor applications exposed to UV or moisture?
TLHG6420 is rated for −40 °C to +85 °C operating temperature and features a tinted diffused epoxy lens, but it is not IP-rated or explicitly qualified for outdoor, high-UV, or condensing-humidity environments. For such use, conformal coating or secondary sealing is recommended. Its RoHS-compliant materials resist yellowing better than older epoxy formulations, but long-term UV exposure may reduce lumen maintenance.
What is the thermal resistance and maximum allowable power dissipation for TLHG6420?
TLHG6420 has a junction-to-solder-point thermal resistance of 325 K/W and a maximum power dissipation of 60 mW. At 20 mA and 2.4 V, it dissipates 48 mW - staying within limit. However, ambient temperature rise above 25 °C requires derating: at 85 °C ambient, max continuous current drops to ~12 mA to maintain Tj ≤ 100 °C. Thermal design must consider PCB copper area and airflow.
