Product details
Overview
VLMD3100-GS18 from Vishay Semiconductors is a red surface-mount LED in PLCC-2 package, featuring 11.2–22 mcd luminous intensity at 10 mA, 648 nm dominant wavelength, ±60° viewing angle, and 1.8–2.2 V forward voltage at 20 mA. It is AEC-Q101 qualified and designed for automotive dashboard backlighting and indicator applications requiring narrow brightness binning.
For engineers reviewing the VLMD3100-GS18 datasheet, VLMD3100-GS18 pinout, VLMD3100-GS18 application, or VLMD3100-GS18 equivalent, this page delivers verified optical, electrical, thermal, and packaging data - including JEDEC level 2a preconditioning, 2 kV ESD rating, and IR reflow compatibility - to support reliable SMT integration and automotive-grade design validation.
Technical Context
This GaAlAs-on-GaAs LED operates with DC forward current up to 30 mA at ≤60 °C ambient, delivering stable red emission with tight luminous intensity ratio (IVmax/IVmin ≤ 1.6 per reel) and low thermal resistance (RthJA = 400 K/W on ≥16 mm² pad). Its non-diffused lens enables efficient coupling to light pipes and LCD backlight guides.
Optical performance is characterized at 10 mA pulse (25 ms), with dominant wavelength temperature coefficient of +0.05 nm/K and forward voltage coefficient of −1.8 mV/K. The device supports automated placement and conforms to CECC 00802 and J-STD-020 soldering profiles, including peak reflow at 260 °C for ≤10 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Pinout & Package
The VLMD3100-GS18 uses a 4-pin PLCC-2 surface-mount package with molded white thermoplastic body, clear epoxy lens, and integrated reflector. Dimensions: 3.5 × 2.8 × 1.9 mm (L × W × H), with 1.6 mm pad spacing and anode/cathode polarity marked on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Positive LED terminal | Connected to current source; requires series resistor or constant-current driver for bias control |
| Cathode (Pin 2) | Negative LED terminal | Connected to ground or sink driver; polarity must be observed to avoid reverse breakdown (VR = 6 V max) |
| Exposed pad (Pin 3/4) | Thermal and mechanical anchor | Not electrically active; must be soldered to ≥16 mm² copper pour for thermal management and mechanical reliability |
Key Features
| Feature | Design Value |

IC Role / Device Role / Timing Role: Discrete LED mounted on front-panel PCB, driven by dedicated LED controller or discrete transistor switch. Use Value: Wide operating temperature range (−40 to +100 °C) ensures reliability in uncontrolled telecom environments; ESD rating prevents field failures during service. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMD3105-GS08 | Same optical specs but higher max luminous intensity (28 mcd) and GS08 tape (7500 pcs/reel) | Preferred where higher brightness margin is required without changing layout | Select when tighter brightness tolerance is not critical and lower reel quantity suffices |
| LHT674-L2N1 (OSRAM) | Identical luminous intensity bin (L2N1), same PLCC-2 package, but 650 nm peak wavelength vs. 648 nm dominant | Drop-in replacement only after verifying color match in final assembly under target lighting | Choose for multi-source procurement where OSRAM supply chain diversification is prioritized |
Compared with VLMD3100-GS18, VLMD3105-GS08 offers higher intensity headroom but less stringent binning control, while LHT674-L2N1 provides second-source availability with minor spectral shift - both require validation of optical alignment and thermal performance in the target PCB layout.

FAQ
What is the maximum continuous forward current for VLMD3100-GS18?
The VLMD3100-GS18 has a DC forward current rating of 30 mA at ambient temperatures ≤60 °C. At higher ambient temperatures, derating is required per Figure 1 in the datasheet - e.g., 20 mA at 85 °C. Exceeding these limits risks accelerated lumen depreciation and junction overheating. Always verify thermal design using the specified 400 K/W junction-to-ambient resistance.
Is VLMD3100-GS18 compatible with lead-free reflow soldering processes?
Yes, VLMD3100-GS18 is fully compatible with lead-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. The recommended profile includes ramp-up ≤3 °C/s, time above 217 °C ≤30 s, and peak hold at 240–245 °C. Preconditioning to JEDEC level 2a is already applied, eliminating need for pre-bake if used within 672 hours of bag opening.
What does the "GS18" suffix indicate in VLMD3100-GS18?
The "GS18" suffix denotes Vishay's preferred tape-and-reel packaging option: 8 mm antistatic blister tape containing 8000 units per reel. This differs from GS08 (7500 units, 5 × 1500 configuration) and reflects optimized logistics for high-volume SMT lines. Both GS08 and GS18 share identical electrical, optical, and mechanical specifications for VLMD3100-GS18.
How is luminous intensity binned for VLMD3100-GS18, and why does it matter?
VLMD3100-GS18 is categorized in the "L" luminous intensity group (11.2–14 mcd min/max), with IVmax/IVmin ≤ 1.6 per reel. This tight binning ensures consistent brightness across all units on a single reel, eliminating post-assembly sorting and reducing calibration effort in automotive and industrial indicator systems where visual uniformity is critical.
Does VLMD3100-GS18 require current-limiting circuitry, and what is the typical drive configuration?
Yes, VLMD3100-GS18 requires external current limiting. A series resistor is typical for low-speed indicator use (e.g., 150 Ω with 3.3 V supply and 20 mA target), while constant-current drivers (e.g., TLC591x, MAX168xx) are recommended for backlighting to maintain stable intensity across voltage and temperature variation. The forward voltage range of 1.8–2.2 V at 20 mA must be accounted for in all designs.
