Product details
Overview
VLMS3101-GS18 from Vishay Semiconductors is a surface-mount red LED in PLCC-2 package, with dominant wavelength 630 nm (±6 nm), luminous intensity 2.8–9.4 mcd at 10 mA, and forward voltage 2.0–2.6 V at 20 mA. It delivers narrow brightness and color binning for indicator and backlighting applications in telecommunication and office equipment.
For engineers reviewing the VLMS3101-GS18 datasheet, VLMS3101-GS18 pinout, VLMS3101-GS18 application, or VLMS3101-GS18 equivalent, this page provides verified optical, electrical, thermal, and packaging data - including JEDEC level 2a preconditioning, ±60° viewing angle, 1 kV ESD rating, and compatibility with IR/vapor-phase/wave soldering per CECC standards.
Technical Context
This red GaAsP-on-GaP LED operates at 10 mA nominal drive current with pulse-tested luminous intensity (25 ms) and exhibits low thermal resistance (400 K/W) when mounted on ≥16 mm² PCB pads. Its non-diffused lens enables efficient coupling to light pipes and LCD backlighting layers.
The device supports automated placement and conforms to EIA/ICE SMD standards. Reverse voltage rating is 6 V, junction temperature limit is 100 °C, and it meets RoHS, lead-free, and halogen-free environmental requirements per Vishay documentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Dominant wavelength | 624–636 nm - ensures consistent red chromaticity for visual indication compliance |
| Luminous intensity | 2.8–9.4 mcd at 10 mA - supports brightness-binned selection for uniform panel appearance |
| Forward voltage | 2.0–2.6 V at 20 mA - enables stable biasing with common 3.3 V or 5 V logic-level current-limiting resistors |
| Viewing angle | ±60° - provides wide, symmetric illumination suitable for front-panel indicators and symbol backlighting |
| Junction capacitance | 7 pF at 0 V - negligible impact on high-speed switching in multiplexed display drivers |
| ESD withstand | 1 kV HBM per JESD22-A114-B - sufficient for handling in standard ESD-safe assembly environments |
| Thermal resistance | 400 K/W - requires minimum 16 mm² copper pad for reliable operation at max 20 mA continuous current |
Pinout & Package
Package: PLCC-2 surface-mount package with white thermoplastic body, embedded lead frame, and clear epoxy-filled reflector. Low-profile design (height ≤ 2.2 mm) optimized for space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input | Connected to current-limiting resistor; polarity must be observed during placement to avoid reverse conduction |
| Cathode (K) | Ground return path | Internally connected to lead frame; serves as thermal and electrical reference node |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables precise optical coupling to light guides and edge-lit LCD backlights without scattering loss |
| Luminous intensity ratio ≤ 1.6 | Ensures uniform brightness across LEDs on same reel - critical for consistent UI appearance in multi-LED arrays |
| JEDEC level 2a preconditioning | Validates moisture sensitivity control for safe lead-free reflow without popcorning or delamination |
| Compatible with 8 mm tape | Supports high-throughput pick-and-place integration using standard feeder systems (e.g., Fuji, Yamaha) |
| Low power consumption | 20 mA max operating current allows direct drive from microcontroller GPIO pins with minimal heat generation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LST670-J1L2 | Same PLCC-2 package, 625–635 nm dominant wavelength, 3–10 mcd at 10 mA - slightly wider intensity range | Identical use in telecom indicators and office equipment; differs in moisture sensitivity labeling and tape packaging format | Select when OSRAM sourcing preference applies or when cross-qualified for legacy BOMs requiring LST670-J1L2 footprint compatibility |
| Vishay VLMS3100-GS08 | Same die, identical optical/electrical specs, but shipped in GS08 tape (1500 pcs/reel) vs. GS18 (3000 pcs/reel) | No functional difference; GS08 used where smaller reel size or shorter lead time is prioritized over volume efficiency | Choose VLMS3101-GS18 for higher-volume production runs requiring 3000-unit reels and optimized logistics cost per unit |
Compared with OSRAM LST670-J1L2 and Vishay VLMS3100-GS08, the VLMS3101-GS18 offers identical photometric performance and mechanical fit but delivers improved supply continuity through larger reel quantity and Vishay's extended lifecycle support for industrial-grade SMD LEDs.

FAQ
What is the maximum continuous forward current for VLMS3101-GS18?
The VLMS3101-GS18 has a maximum DC forward current of 20 mA at ambient temperatures ≤74 °C. Exceeding this value risks accelerated degradation and reduced lifetime. Derating is required above 74 °C per the absolute maximum ratings table in the Vishay datasheet, and thermal management via adequate PCB copper area is essential to maintain junction temperature below 100 °C.
Does VLMS3101-GS18 require special handling due to moisture sensitivity?
Yes, VLMS3101-GS18 is moisture-sensitive per JEDEC level 2a and ships in dry-packed antistatic reels with humidity indicator labels. After opening the sealed bag, it must be mounted within 672 hours at ≤30 °C/60 % RH or stored in <10 % RH dry boxes. If exposed beyond limits, baking at 60 °C for 96 hours under <5 % RH is required before reflow soldering to prevent popcorning.
What is the viewing angle specification for VLMS3101-GS18 and how does it affect layout?
The VLMS3101-GS18 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50 % at 60° off-axis. This wide, symmetric viewing cone simplifies front-panel design by allowing flexible LED placement relative to user line-of-sight and eliminates need for secondary optics in most indicator applications.
Can VLMS3101-GS18 be used in reverse-bias configurations?
The VLMS3101-GS18 supports short-term reverse-bias operation up to 6 V, as noted in the datasheet's Absolute Maximum Ratings. However, sustained reverse conduction is not recommended - it provides no functional benefit and may accelerate degradation. Use only in standard forward-biased configuration for reliable long-term performance.
Is VLMS3101-GS18 compatible with lead-free reflow soldering processes?
Yes, VLMS3101-GS18 is qualified for lead-free reflow per J-STD-020, with peak package body temperature up to 260 °C for ≤10 seconds. Vishay specifies a ramp-up rate ≤3 °C/s, time above 217 °C ≤60 s, and cooling rate ≤6 °C/s. The device also passes vapor-phase and wave soldering per CECC standards when using recommended profiles.
