Product details
Overview
VLMS3101-GS08 from Vishay Semiconductors is a surface-mount red LED in PLCC-2 package, with dominant wavelength 630 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 (IVmax/IVmin ≤ 1.6) for consistent backlighting and indicator use in office and telecom equipment.
For engineers reviewing the VLMS3101-GS08 datasheet, VLMS3101-GS08 pinout, VLMS3101-GS08 application, or VLMS3101-GS08 equivalent, key selection criteria include its ±60° viewing angle, low-profile non-diffused lens for light-pipe coupling, JEDEC level 2a preconditioning, 1 kV ESD rating, and compatibility with IR reflow and wave soldering per CECC standards.
Technical Context
This red GaAsP-on-GaP LED operates at 10 mA test current for photometric characterization and 20 mA for forward voltage rating. Its optical performance is defined by dominant wavelength (624–636 nm), peak wavelength (~640 nm), and angular intensity distribution centered at 0° with half-intensity at ±60°.
Thermal design relies on RthJA = 400 K/W when mounted on ≥16 mm² PCB pad, supporting operation from –40 °C to +100 °C ambient. Absolute maximum ratings include 6 V reverse voltage, 20 mA DC forward current, and 260 °C peak soldering temperature for ≤5 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Red, defined by dominant wavelength 624–636 nm - ensures visual consistency in indicator applications. |
| Luminous intensity | 2.8–9.4 mcd at 10 mA - enables precise brightness matching across units within same reel. |
| Forward voltage | 2.0–2.6 V at 20 mA - determines series resistor sizing and power budget in 3.3 V or 5 V logic-level drive circuits. |
| Viewing angle | ±60° half-intensity - provides wide, uniform illumination for front-panel indicators and LCD backlighting. |
| Junction capacitance | 7 pF at 0 V, 1 MHz - negligible impact on typical DC/low-frequency LED switching applications. |
| ESD withstand | 1 kV per JESD22-A114-B - supports handling in standard assembly environments without special grounding protocols. |
| Package | PLCC-2 SMD - compatible with automated placement and reflow processes; footprint requires 2.8 mm × 2.2 mm board area. |
Pinout & Package
PLCC-2 package: 2-pin surface-mount lead frame embedded in white thermoplastic, with clear epoxy-filled reflector cavity and non-diffused lens. Low-profile construction (height ≤ 1.9 mm) supports tight mechanical stacking in space-constrained assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source or microcontroller GPIO via current-limiting resistor; polarity must be observed during placement. |
| Cathode (K) | Negative terminal | Typically tied to ground or sink driver; marked by notch or chamfer on package edge per Vishay PLCC-2 mechanical drawing. |
Key Features
| Feature | Design Value |
|---|---|
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 per reel - eliminates manual brightness sorting in high-volume indicator assembly. |
| Non-diffused lens | Enables >85% optical coupling efficiency into light pipes - reduces backlight leakage and improves contrast in symbol illumination. |
| JEDEC level 2a preconditioning | Qualified for moisture-sensitive handling without baking unless exposed >672 h at >30 °C / 60 % RH - simplifies SMT line logistics. |
| Lead (Pb)-free reflow profile support | Rated for peak 255–260 °C per J-STD-020 - compatible with standard lead-free assembly lines without process deviation. |
Applications
| Telecom Indicator | A/V Equipment Backlight |
|---|---|
Use Scenario: Status indication on telephone handsets and fax machine control panels. IC Role / Device Role / Timing Role: Visual status emitter driven by microcontroller GPIO or discrete transistor switch. Use Value: High brightness-to-current ratio (up to 9.4 mcd @ 10 mA) minimizes power draw while maintaining visibility in ambient light. | Use Scenario: Keypad and display backlighting in stereo receivers and DVD players. IC Role / Device Role / Timing Role: Constant-current driven light source aligned with light guide for even panel illumination. Use Value: ±60° viewing angle and non-diffused lens ensure directional coupling into light pipes, reducing cross-talk between adjacent keys. |
| Office Equipment Symbol Light | LCD Flat Backlight |
Use Scenario: Power-on, ready, and error symbols on printers, scanners, and copiers. IC Role / Device Role / Timing Role: Steady-state or PWM-modulated emitter controlled by system MCU. Use Value: Tight dominant wavelength tolerance (624–636 nm) guarantees uniform red hue across multi-LED arrays, avoiding color mismatch in branding-critical UIs. | Use Scenario: Edge-lit backlight for monochrome character LCDs in industrial HMIs and point-of-sale terminals. IC Role / Device Role / Timing Role: Primary light source coupled to acrylic light guide with reflective dot pattern. Use Value: Low thermal resistance (RthJA = 400 K/W) allows sustained 20 mA operation without derating at 70 °C ambient - extends lifetime in enclosed enclosures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LST670-J1L2 | Same PLCC-2 package, 625–635 nm dominant wavelength, 3–10 mcd @ 10 mA - slightly tighter intensity binning (IVmax/IVmin ≤ 1.5). | Identical mounting and optical interface; validated for automotive interior lighting per AEC-Q101. | Select for automotive-qualified supply chains where extended temperature validation is required. |
| Vishay VLMS3100-GS08 | Identical die technology and PLCC-2 package; differs only in luminous intensity bin group - VLMS3100-GS08 ships H/J/K/L groups, VLMS3101-GS08 ships specific intensity subset per order. | No functional difference; used interchangeably where brightness group alignment is not critical. | Choose when sourcing from existing VLMS3100 inventory or requiring documented traceability to same production lot family. |
Compared with OSRAM LST670-J1L2 and Vishay VLMS3100-GS08, the VLMS3101-GS08 offers identical optical and thermal specifications but targets narrower intensity binning control per reel - advantageous for applications demanding batch-level brightness uniformity without post-production sorting.

FAQ
What is the maximum continuous forward current rating for VLMS3101-GS08?
The VLMS3101-GS08 has a DC forward current rating of 20 mA at ambient temperatures ≤74 °C. Exceeding this value risks accelerated lumen depreciation and junction overheating. Derating is required above 74 °C per the datasheet's forward current vs. ambient temperature curve, with zero current allowed above 100 °C ambient.
Does VLMS3101-GS08 require baking before reflow soldering?
VLMS3101-GS08 is shipped in JEDEC level 2a dry-packed reels and does not require baking if mounted within 672 hours of opening the moisture barrier bag under ≤30 °C / 60 % RH conditions. Baking (e.g., 96 h at 60 °C <5 % RH) is mandatory only after exposure beyond that threshold or if the humidity indicator card shows >10 % RH.
What is the significance of the "GS08" suffix in VLMS3101-GS08?
The "GS08" suffix denotes Vishay's standard 8 mm antistatic blister tape packaging option, containing 1500 pieces per reel. It specifies tape width, cavity dimensions, top tape adhesion, and reel diameter (178–180 mm), ensuring compatibility with all major pick-and-place machines calibrated for EIA-481-D compliant feeders.
Can VLMS3101-GS08 be driven directly from a 3.3 V microcontroller GPIO?
Yes, VLMS3101-GS08 can be driven directly from a 3.3 V GPIO when paired with an appropriate current-limiting resistor. At 20 mA forward current and 2.6 V max VF, a 36 Ω resistor (standard 39 Ω) yields ~18 mA - within absolute maximum rating and sufficient for most indicator applications.
Is VLMS3101-GS08 RoHS and REACH compliant?
Yes, VLMS3101-GS08 is RoHS-compliant (lead-free terminations) and halogen-free per Vishay's material declaration Doc. #99912. It carries full environmental compliance markings (RoHS, Pb-free, halogen-free) on its bar code label and meets EU REACH SVHC thresholds for all listed substances.
