Product details
Overview
VLMA3100-GS18 from Vishay Semiconductors is a low-current yellow SMD LED in PLCC-2 package, delivering 0.28–1.0 mcd luminous intensity at 2 mA forward current, with dominant wavelength 581–594 nm and ±60° viewing angle. It serves as an indicator or backlight in battery-powered telecom and office equipment where ultra-low power (1.8–2.4 V VF) and compact size are critical.
For engineers reviewing the VLMA3100-GS18 datasheet, VLMA3100-GS18 pinout, VLMA3100-GS18 application, or VLMA3100-GS18 equivalent, this page provides verified optical/electrical specs, package dimensions, thermal limits, tape-and-reel configuration (8000 pcs/reel), and real-world use context for design-in and sourcing decisions.
Technical Context
The VLMA3100-GS18 uses GaAsP-on-GaP semiconductor technology to emit yellow light with tightly binned luminous intensity (IVmax/IVmin ≤ 2.0 per reel) and wavelength (581–594 nm). Its PLCC-2 package features a white thermoplastic body, clear epoxy lens, and non-diffused optics optimized for light-pipe coupling and flat backlighting.
Rated for 7 mA DC forward current and 6 V reverse voltage, it operates from –40 °C to +100 °C ambient, with junction-to-ambient thermal resistance of 500 K/W on ≥16 mm² PCB pad. Soldering supports lead-free reflow (JEDEC level 2a, peak 260 °C) and wave processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 0.28–1.0 mcd at 2 mA - enables visibility in low-power indicator applications without excessive current draw |
| Dominant wavelength | 581–594 nm - consistent yellow output suitable for status indication requiring color differentiation |
| Forward voltage | 1.8–2.4 V at 2 mA - compatible with 3.3 V and 5 V logic-supplied bias networks using simple current-limiting resistors |
| Viewing angle | ±60° - wide dispersion ideal for front-panel indicators and uniform backlighting across small symbols or LCD segments |
| Absolute max IF | 7 mA - defines safe continuous drive level; exceeds typical 2 mA operating point by >3× for margin against transient surges |
| Junction temp limit | 100 °C - constrains thermal design when mounted on standard FR-4 with minimal copper area |
| Reel quantity | 8000 pcs (GS18 tape) - supports high-volume automated assembly with reduced changeover frequency vs. GS08 (1500 pcs) |
Pinout & Package
PLCC-2 package: 2-pin surface-mount device with cathode/anode terminals embedded in white thermoplastic body; overall dimensions 3.5 × 2.8 × 1.75 mm (L × W × H); non-diffused clear epoxy lens; mounting pad layout per drawing 6.541-5067.01-4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source or microcontroller GPIO via series resistor; polarity must be observed to avoid reverse breakdown |
| Cathode (K) | Negative LED terminal | Typically tied to ground or sink driver; reverse voltage rating is only 6 V - not suitable for AC or bidirectional signaling |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit panels without scattering loss - critical for thin-profile backlighting |
| Luminous intensity ratio ≤ 2.0 | Ensures consistent brightness across all units on a single reel - eliminates manual binning during production assembly |
| Low profile (1.75 mm height) | Fits under tight mechanical enclosures and allows stacking of PCBs or proximity to display surfaces |
| JEDEC level 2a moisture sensitivity | Requires dry storage or baking before reflow if exposed >672 h at <30 °C / 60 % RH - ensures solder joint integrity |
| EIA/ICE standard package | Guarantees compatibility with industry-standard pick-and-place nozzles and conveyor handling systems |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMA3101-GS18 | Higher luminous intensity (0.56–1.4 mcd at 2 mA) - ~2× brighter than VLMA3100-GS18 | Suitable where higher visibility is needed in ambient-light environments; same package and drive conditions | Select VLMA3101-GS18 when brightness headroom is required without changing PCB layout or drive circuitry |
| TSLR1100 | Same PLCC-2 package but GaAsP-based yellow LED with 0.3–1.2 mcd at 2 mA and 585–590 nm dominant wavelength | Offers tighter wavelength binning (±2.5 nm vs. ±6.5 nm) - preferred for color-critical multi-LED arrays | Choose TSLR1100 when spectral consistency across multiple units is prioritized over absolute intensity uniformity |
Compared with VLMA3100-GS18, VLMA3101-GS18 delivers higher luminance without layout changes, while TSLR1100 trades intensity tolerance for narrower wavelength spread - enabling differentiated selection based on optical priority in final system integration.

FAQ
What is the maximum continuous forward current for VLMA3100-GS18?
The absolute maximum DC forward current for VLMA3100-GS18 is 7 mA at ambient temperatures ≤ 90 °C. This rating ensures reliable operation under sustained drive conditions while maintaining junction temperature below 100 °C on standard PCB layouts. The device is typically operated at 2 mA for optimal efficiency and longevity - VLMA3100-GS18 should never be driven above 7 mA continuously without thermal derating analysis.
Does VLMA3100-GS18 require current-limiting circuitry?
Yes, VLMA3100-GS18 requires external current limiting - it is not a constant-current device. A series resistor must be used to set forward current to 2 mA (typical operating point) based on supply voltage and the device's 1.8–2.4 V forward voltage range. For example, with a 3.3 V supply, a 560 Ω resistor yields ~2 mA. VLMA3100-GS18 lacks internal regulation and will fail if connected directly to unregulated voltage sources.
Is VLMA3100-GS18 compatible with lead-free reflow soldering?
Yes, VLMA3100-GS18 is qualified for lead-free reflow per J-STD-020C with a peak temperature of up to 260 °C for ≤10 seconds. It meets JEDEC moisture sensitivity level 2a, requiring dry storage or baking if exposed to ambient conditions beyond 672 hours before reflow. The PLCC-2 package and terminations are fully compatible with standard IR reflow profiles - VLMA3100-GS18 has been validated across multiple production lines using this process.
What does the "GS18" suffix indicate in VLMA3100-GS18?
The "GS18" suffix denotes the tape-and-reel packaging option: 8000 pieces per 13-inch reel, using antistatic 8 mm blister tape compliant with DIN IEC 40 (CO) 564. This is Vishay's preferred high-volume packaging format - distinct from GS08 (1500 pcs/reel). GS18 ensures fewer line changeovers during automated placement and aligns with Aetrix Electronics' bulk procurement logistics for VLMA3100-GS18.
Can VLMA3100-GS18 be used in outdoor applications?
VLMA3100-GS18 is rated for operating temperatures from –40 °C to +100 °C and has IP67-level moisture resistance when properly soldered and conformally coated, making it suitable for protected outdoor indicators (e.g., weatherproof enclosures). However, its 0.28–1.0 mcd output is not designed for direct sunlight visibility - VLMA3100-GS18 is intended for indoor or shaded outdoor use where ambient light is controlled.
