Product details
Overview
VLMC3101-GS08 from Vishay Semiconductors is a green low-current surface-mount LED in PLCC-2 package, delivering 1.12–2.0 mcd luminous intensity at 2 mA forward current, with dominant wavelength 562–575 nm and ±60° viewing angle-designed for indicator and backlighting in battery-powered office and telecom equipment.
For engineers reviewing the VLMC3101-GS08 datasheet, VLMC3101-GS08 pinout, VLMC3101-GS08 application, or VLMC3101-GS08 equivalent, key selection criteria include luminous intensity binning (Group F), GaP-on-GaP die technology, JEDEC Level 2a moisture sensitivity, and compatibility with IR reflow per J-STD-020.
Technical Context
This device operates as a low-power visible-light emitter optimized for 2 mA DC forward current, with absolute maximum ratings of 7 mA continuous forward current and 6 V reverse voltage. Its thermal resistance junction-to-ambient is 500 K/W when mounted on a PCB pad >16 mm², supporting operation from –40 °C to +100 °C ambient.
The PLCC-2 package features a white thermoplastic body with embedded lead frame and clear epoxy-filled reflector, enabling non-diffused lens performance ideal for light-pipe coupling. Luminous intensity ratio within one reel is controlled to ≤1.6 (IVmax/IVmin), ensuring consistent brightness across shipped units.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 1.12–2.0 mcd at 2 mA - defines visible brightness level for human-eye detection in low-power indicator use |
| Dominant wavelength | 562–575 nm - specifies green spectral output suitable for high-visibility status indication |
| Forward voltage | 1.9–2.4 V at 2 mA - determines minimum supply headroom and series resistor sizing |
| Viewing angle | ±60° - sets beam spread for uniform illumination across small panel areas or symbols |
| Absolute max forward current | 7 mA at Tamb ≤ 90 °C - limits continuous drive to prevent thermal degradation and lumen depreciation |
| Junction-to-ambient thermal resistance | 500 K/W - quantifies self-heating under standard mounting; requires adequate PCB copper area for thermal management |
| Moisture sensitivity level | JEDEC Level 2a - mandates dry-packaging and ≤672 h exposure before reflow unless baked per JESD22-A112 |
Pinout & Package
Package: PLCC-2 (equivalent to size B tantalum capacitor), 3.5 mm × 2.8 mm footprint, 1.75 mm height, with non-diffused lens and white thermoplastic body. Lead frame embedded in housing; anode and cathode terminals exposed on underside.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source or microcontroller GPIO via current-limiting resistor; polarity must be observed to avoid reverse breakdown |
| Cathode (K) | Negative LED terminal | Connected to ground or sink driver; reverse voltage rating limited to 6 V - not intended for bidirectional signaling |
Key Features
| Feature | Design Value |
|---|---|
| Low-current operation | Rated at 2 mA typical drive - reduces power consumption and extends battery life in portable devices |
| Non-diffused lens | Enables efficient coupling into light pipes and edge-lit LCD backlights without scattering loss |
| Luminous intensity binning control | IVmax/IVmin ≤ 1.6 per reel - ensures predictable brightness matching across production units |
| Solder process compatibility | Qualified for IR reflow, vapor phase, and wave soldering per CECC 00802 and J-STD-020 - supports automated assembly |
| JEDEC Level 2a preconditioning | Validated for moisture-sensitive handling - eliminates risk of popcorning during reflow if stored and processed correctly |
Applications
| Telecom Indicator | Office Equipment Backlight |
|---|---|
Use Scenario: Status indication on telephone handsets and fax machines where space and power are constrained. IC Role / Device Role / Timing Role: Visible light emitter providing user-recognizable operational feedback. Use Value: 1.12–2.0 mcd output at 2 mA enables clear visibility under ambient lighting while drawing minimal current from line-powered or backup supplies. |
Use Scenario: Backlighting of membrane switches and LCD segments in printers, copiers, and scanners. IC Role / Device Role / Timing Role: Low-profile SMD light source aligned with light-guide geometry. Use Value: Non-diffused lens and ±60° viewing angle deliver directional illumination into narrow optical paths, minimizing crosstalk between adjacent symbols. |
| Battery-Powered Audio/Video | Outdoor Small Indicator |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current green SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMC3100-GS08 | Luminous intensity bin E (0.71–0.9 mcd) vs. VLMC3101-GS08's bin F (1.12–1.4 mcd); otherwise identical electrical/optical specs and packaging | Lower brightness suitable where reduced visual impact or lower power draw is prioritized | Select VLMC3100-GS08 only when brightness consistency within tighter mcd range is required and lower output is acceptable |
| TLR1100G | Same PLCC-2 package, but GaAsP-on-GaP die; dominant wavelength 565–575 nm, VF 2.0–2.5 V, IV 1.0–1.8 mcd at 2 mA | Higher forward voltage tolerance and slightly broader wavelength tolerance - less critical for general-purpose indication | Choose TLR1100G when sourcing flexibility is needed and minor VF/λd variation is acceptable in cost-sensitive designs |
Compared with VLMC3101-GS08, VLMC3100-GS08 offers lower luminous intensity for dimmer indicators, while TLR1100G provides alternative material system and wider parameter tolerances - neither is pin-compatible in the sense of guaranteed identical optical alignment or binning control, but both serve overlapping low-current green LED use cases.

FAQ
What is the luminous intensity range of the VLMC3101-GS08?
The VLMC3101-GS08 has a luminous intensity range of 1.12–2.0 mcd at 2 mA forward current, corresponding to Group F binning per Vishay's classification table. This range ensures consistent brightness across reels, with IVmax/IVmin ≤ 1.6 within each packaging unit. The VLMC3101-GS08 is tested using a 25 ms current pulse and calibrated to ±11 % accuracy.
Is the VLMC3101-GS08 compatible with lead-free reflow soldering?
Yes, the VLMC3101-GS08 is qualified for lead-free IR reflow soldering per J-STD-020, with a peak package body temperature limit of 260 °C for ≤10 s. Its PLCC-2 package withstands standard reflow profiles, including ramp rates up to 3 °C/s and cooling rates up to 6 °C/s. The VLMC3101-GS08 also supports vapor-phase and wave soldering per CECC 00802.
What is the viewing angle specification for the VLMC3101-GS08?
The VLMC3101-GS08 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50 % of its axial value at ±60° off-center. This symmetric viewing profile supports wide-angle visibility in panel-mounted indicators and uniform illumination across flat backlight targets. The VLMC3101-GS08 uses a non-diffused lens, preserving directionality for light-pipe coupling.
Does the VLMC3101-GS08 require baking before reflow if the moisture barrier bag is opened?
Yes - the VLMC3101-GS08 is rated JEDEC Level 2a and must be baked if exposed >672 hours at ≤30 °C and ≤60 % RH after opening the dry bag. Recommended bake conditions are 96 h at 60 °C ±5 °C and <5 % RH for reels, or 192 h at 40 °C ±5 °C and <5 % RH. The VLMC3101-GS08 moisture label is printed on the aluminum bag per JESD22-A112.
What is the forward voltage range of the VLMC3101-GS08 at its rated current?
The VLMC3101-GS08 has a forward voltage range of 1.9–2.4 V at 2 mA DC forward current. This range reflects manufacturing variation in the GaP-on-GaP die and is used to calculate appropriate series resistor values for constant-current drive. The VLMC3101-GS08 forward voltage decreases slightly with rising ambient temperature, as shown in Figure 7 of the datasheet.
