Product details
Overview
TLMB3104-GS08 from Vishay is a blue surface-mount LED using GaN-on-SiC technology in PLCC-2 package, with luminous intensity 5.0–12.5 mcd at 10 mA, 466 nm dominant wavelength, ±60° viewing angle, and 3.9–4.5 V forward voltage at 20 mA. It serves as indicator/backlight in automotive dashboards and office equipment.
For engineers reviewing the TLMB3104-GS08 datasheet, TLMB3104-GS08 pinout, TLMB3104-GS08 application, or TLMB3104-GS08 equivalent, key selection criteria include luminous intensity binning (IVmax/IVmin ≤ 1.6 per unit), non-diffused lens for light-pipe coupling, ESD Class 1 rating, and compatibility with IR/vapor-phase/wave soldering processes.
Technical Context
This device operates as a visible-light emitter optimized for uniform visual appearance in multi-LED assemblies, enabled by factory luminous intensity grouping. Its GaN-on-SiC die delivers stable blue output with peak wavelength at 428 nm and dominant wavelength at 466 nm under 10 mA drive.
The PLCC-2 package features a white thermoplastic body over a lead frame, conforms to EIA/ICE standards, and supports reflow profiles up to 260 °C for 5 s. Thermal resistance junction-to-ambient is 400 K/W when mounted on ≥16 mm² PCB pad area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 5.0–12.5 mcd at IF = 10 mA; enables consistent brightness matching across LEDs in same packaging unit |
| Dominant wavelength | 466 nm; defines perceived blue color for human vision applications |
| Forward voltage | 3.9–4.5 V at IF = 20 mA; determines minimum supply headroom and series resistor sizing |
| Viewing angle | ±60° half-intensity; defines usable illumination cone for backlight or indicator placement |
| Max DC forward current | 20 mA at Tamb ≤ 60 °C; sets continuous drive limit for thermal reliability |
| Junction temperature | 100 °C maximum; constrains ambient + self-heating budget in enclosed designs |
| ESD rating | Class 1 per ANSI/ESDA-JEDEC JS-001; requires handling precautions during assembly |
Pinout & Package
TLMB3104-GS08 uses PLCC-2 package: 2-pin surface-mount plastic-leaded chip carrier with white thermoplastic body, lead frame embedded, non-diffused lens, and EIA/ICE standard footprint. Mounting pad layout matches size B tantalum capacitor outline (3.5 mm × 2.8 mm body, 1.65 mm pin pitch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Positive LED terminal | Connected to current-limiting resistor or driver output; polarity must be observed to avoid reverse breakdown |
| Cathode (Pin 2) | Negative LED terminal | Typically tied to ground or low-side switch; pin 2 is marked by chamfered corner on package top view |
Key Features
| Feature | Design Value |
|---|---|
| GaN-on-SiC die technology | Enables high-efficiency blue emission with superior thermal stability vs. AlInGaP or older SiC-only LEDs |
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 within one tape unit ensures uniform visual appearance without manual sorting |
| Non-diffused lens | Preserves directional output for efficient coupling into light pipes or edge-lit LCD backlights |
| Lead-free construction | Meets RoHS Directive 2011/65/EU and eliminates Pb contamination risk in SMT reflow |
| Solder process compatibility | Validated for infrared, vapor-phase, and wave soldering per CECC standards-no special profile needed |

Equivalent & Alternatives
The following parts are listed as comparable options for similar blue LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLMB3106-GS08 | Higher luminous intensity range: 5.0–20.0 mcd vs. 5.0–12.5 mcd | Better suited for applications requiring higher brightness in ambient-light environments | Select TLMB3106-GS08 only if >12.5 mcd typical output is required; otherwise TLMB3104-GS08 offers tighter binning control |
| TLMB3101-GS08 | Lower luminous intensity range: 4.0–12.5 mcd; min IV reduced by 1.0 mcd | Acceptable where lower minimum brightness suffices and cost sensitivity is higher | TLMB3101-GS08 may reduce BOM cost but lacks guaranteed 5.0 mcd minimum; verify system visibility margin |
Compared with TLMB3101-GS08 and TLMB3106-GS08, TLMB3104-GS08 provides the optimal balance of guaranteed minimum intensity (5.0 mcd), upper limit (12.5 mcd), and binning consistency (IVmax/IVmin ≤ 1.6), making it preferred for applications demanding predictable visual performance across production units.

FAQ
What is the luminous intensity range of TLMB3104-GS08 at 10 mA drive current?
The TLMB3104-GS08 has a luminous intensity range of 5.0 to 12.5 mcd when tested at 10 mA and Tamb = 25 °C. This range is guaranteed per packaging unit, with IVmax/IVmin ≤ 1.6 to ensure visual uniformity across LEDs in the same tape reel. The TLMB3104-GS08 is binned to meet this specification during final test.
Does TLMB3104-GS08 support standard reflow soldering processes?
Yes, TLMB3104-GS08 is qualified for infrared, vapor-phase, and wave soldering per CECC standards. Its PLCC-2 package withstands peak reflow temperatures up to 260 °C for 5 seconds. The device is lead-free and RoHS-compliant, eliminating Pb-related wetting or dewetting risks during standard SMT assembly. TLMB3104-GS08 does not require special thermal profiling beyond JEDEC J-STD-020 guidelines.
What is the dominant wavelength and peak wavelength of TLMB3104-GS08?
The TLMB3104-GS08 has a dominant wavelength of 466 nm and a peak wavelength of 428 nm, both measured at IF = 10 mA and Tamb = 25 °C. Dominant wavelength defines the perceived blue hue for human observers, while peak wavelength indicates the spectral power maximum-critical for optical filter matching. TLMB3104-GS08 maintains these values across its operating temperature range.
Is TLMB3104-GS08 suitable for automotive applications?
Yes, TLMB3104-GS08 is rated for operation from -40 to +100 °C ambient temperature and qualified for automotive dashboard backlighting and switch illumination. Its GaN-on-SiC die provides stable blue output under thermal cycling, and its PLCC-2 package passes vibration and thermal shock tests per AEC-Q200 recommendations. TLMB3104-GS08 is used in production automotive instrumentation systems.
What is the maximum DC forward current rating for TLMB3104-GS08?
The maximum DC forward current for TLMB3104-GS08 is 20 mA when ambient temperature is ≤ 60 °C. At higher ambient temperatures, derating applies per Figure 2 in the datasheet-e.g., ~15 mA at 85 °C. Exceeding 20 mA continuously risks accelerated degradation and luminous flux decline. TLMB3104-GS08 must be operated within this limit to maintain rated lifetime and intensity stability.
