Product details
Overview
TLHG4900 from Vishay Semiconductors is a high-brightness green LED in a standard Ø 3 mm clear plastic package (T-1), delivering 16–37 mcd luminous intensity at 10 mA, with dominant wavelength 562–575 nm and ±16° viewing angle-designed for status indication and legend lighting where visual uniformity and directional brightness are critical.
For engineers reviewing the TLHG4900 datasheet, TLHG4900 pinout, TLHG4900 application, or TLHG4900 equivalent, this page provides verified optical/electrical specs, package dimensions, binning categories, absolute maximum ratings, and real-world selection guidance for industrial indicator and panel-mount lighting designs.
Technical Context
The TLHG4900 uses GaP-on-GaP epitaxial technology to achieve green emission with narrow spectral distribution and high luminous efficacy. Its ±16° half-intensity angle enables focused beam control without external optics, supporting high-contrast visual signaling in ambient-lit environments.
It operates within -40 °C to +100 °C ambient range, supports DC and pulsed drive (up to 1 A surge), and is categorized into luminous intensity groups (e.g., S: 16–32 mcd) and wavelength subgroups (e.g., green Group 5: 566–569 nm) to ensure consistent appearance across production batches.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 16–37 mcd @ 10 mA - ensures high-visibility status indication at low drive current |
| Dominant wavelength | 562–575 nm - defines true green color output compliant with IEC 62471 photobiological safety |
| Viewing angle | ±16° half-intensity - delivers directional brightness ideal for front-panel legend illumination |
| Forward voltage | 2.4–3.0 V @ 20 mA - compatible with standard 3.3 V or 5 V logic-level current-limiting resistor drives |
| Absolute max forward current | 30 mA continuous @ ≤60 °C - sets thermal derating boundary for PCB layout and heatsinking |
| Junction-to-ambient thermal resistance | 400 K/W - confirms suitability for compact through-hole mounting without forced cooling |
| Reverse voltage rating | 6 V - defines minimum reverse protection diode requirement in AC-coupled or bidirectional drive circuits |
Pinout & Package
TLHG4900 is a two-terminal through-hole LED in standard Ø 3 mm (T-1) clear plastic package per drawing 6.544-5255.02-4: body diameter 2.9 ± 0.1 mm, length 6.1 ± 0.3 mm, lead spacing 2.54 mm nominal, cathode indicated by flat side and shorter lead.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (longer lead) | Positive DC input terminal | Must be connected to current source or resistor network; polarity reversal prevents conduction |
| Cathode (shorter lead, flat side) | Negative/return terminal | Identified by physical marking; connects to ground or sink driver; reverse bias must not exceed 6 V |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | Group S (16–32 mcd) enables consistent brightness matching across multi-LED panels |
| Wavelength binning | Green subgroups (e.g., 566–569 nm) ensure uniform chromaticity in color-critical status displays |
| Small mechanical tolerances | ±0.1 mm body diameter and ±0.3 mm length support automated insertion and tight panel cutouts |
| High peak current capability | 1 A surge rating (tp ≤ 10 μs) allows PWM dimming up to 100 kHz without degradation |
| DC and pulsed operation | Rated for continuous 30 mA or high-duty-cycle pulsing-supports both static indicators and blinking UI elements |
Applications
| Status lights | Off / on indicator |
|---|---|
Use Scenario: Front-panel power and fault status indication on industrial PLCs and power supplies. IC Role / Device Role / Timing Role: Visual output device providing human-readable system state feedback.

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 TLHG5400 | Same Ø 3 mm package, higher luminous intensity (25–50 mcd), wider viewing angle (±20°) | Better suited for wide-angle visibility; less directional than TLHG4900 | Select TLHG5400 when broader viewing cone is required; TLHG4900 preferred for focused legend lighting |
| ROHM SSL-LX3053GD | Ø 3 mm package, 20–40 mcd, dominant wavelength 565–575 nm, RthJA = 350 K/W | Slightly lower thermal resistance enables marginally higher continuous current in confined layouts | Choose SSL-LX3053GD if thermal budget is constrained; TLHG4900 offers tighter wavelength binning for color-matching |
Compared with TLHG5400 and SSL-LX3053GD, TLHG4900 provides the narrowest viewing angle (±16°) and most granular green wavelength binning-making it optimal for applications demanding precise chromatic consistency and directional brightness control in compact indicator arrays.

FAQ
What is the maximum continuous forward current for TLHG4900?
The TLHG4900 has a maximum DC forward current of 30 mA at ambient temperatures ≤60 °C. Exceeding this value requires thermal derating per the datasheet's Fig. 1, and junction temperature must remain below 100 °C. At 25 °C ambient, TLHG4900 can sustain 30 mA continuously with proper PCB copper area; TLHG4900 reliability degrades rapidly above 35 mA without active cooling.
Does TLHG4900 support PWM dimming, and what is its surge current rating?
Yes, TLHG4900 supports PWM dimming with a peak forward surge current rating of 1 A for pulse widths ≤10 μs. This enables high-frequency (≥10 kHz) dimming without thermal stress. The TLHG4900's GaP-on-GaP structure exhibits fast turn-on/turn-off response, making it suitable for strobed or multiplexed display applications where TLHG4900 brightness must be precisely modulated.
How is luminous intensity binned for TLHG4900, and why does it matter?
TLHG4900 is binned into luminous intensity groups (e.g., Group S: 16–32 mcd) and shipped in single-group reels to ensure visual uniformity. This matters because TLHG4900 devices from the same reel will exhibit matched brightness-critical for multi-LED status panels where mismatched intensity would degrade perceived quality and readability.
What is the dominant wavelength range of TLHG4900, and how is it categorized?
The TLHG4900 has a dominant wavelength range of 562–575 nm and is further categorized into eight green wavelength subgroups (e.g., Group 5: 566–569 nm). This fine binning allows designers to select TLHG4900 units with tightly matched chromaticity-essential for applications like medical device indicators where regulatory compliance requires consistent green hue across production lots.
Is TLHG4900 RoHS-compliant and halogen-free?
Yes, TLHG4900 complies with RoHS Directive 2011/65/EU and is halogen-free per Vishay specification document 99912. Material declarations confirm no brominated flame retardants, chlorine, or fluorine above threshold limits. TLHG4900 meets JEDEC J-STD-609A Class 1 for moisture sensitivity and is rated for lead-free reflow up to 260 °C for 5 seconds.
