Product details
Overview
VLMT3100-GS08 from Vishay Semiconductors is a low-current red surface-mount LED in PLCC-2 package, delivering 0.28–1.1 mcd luminous intensity at 2 mA forward current, with dominant wavelength 612–625 nm and forward voltage 1.7–2.4 V. It serves as an indicator or backlight in battery-powered and space-constrained equipment.
For engineers reviewing the VLMT3100-GS08 datasheet, VLMT3100-GS08 pinout, VLMT3100-GS08 application, or VLMT3100-GS08 equivalent, key selection factors include its ±60° viewing angle, non-diffused lens for light-pipe coupling, 7 mA absolute maximum forward current, and compatibility with IR/vapor-phase/wave soldering per CECC standards.
Technical Context
The VLMT3100-GS08 uses GaAsP-on-GaP semiconductor technology to emit red light with peak wavelength at 635 nm and dominant wavelength tightly binned between 612 nm and 625 nm. Its PLCC-2 package features a white thermoplastic body with clear epoxy-filled reflector and non-diffused lens.
Designed for low-power operation, it achieves luminous intensity ratio IVmax/IVmin ≤ 1.6 within one tape reel, ensuring consistent brightness across units. 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.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 0.28–1.1 mcd at 2 mA - enables visibility in low-power indicator applications without excessive current draw |
| Dominant wavelength | 612–625 nm - delivers standard red color suitable for status indication and human-perceptible signaling |
| Forward voltage | 1.7–2.4 V at 2 mA - compatible with 3.3 V and 5 V logic-supplied bias networks using simple series resistor |
| Viewing angle | ±60° - provides wide angular coverage for front-panel indicators and uniform backlighting of symbols |
| Absolute max forward current | 7 mA at Tamb ≤ 90 °C - defines safe continuous drive level for long-term reliability in compact layouts |
| Junction temperature limit | 100 °C - constrains thermal design margin when operating in sealed enclosures or high-ambient environments |
| Reverse voltage rating | 6 V - allows brief reverse-bias use (e.g., multiplexed displays) without degradation |
Pinout & Package
The VLMT3100-GS08 is housed in a 2-terminal PLCC-2 surface-mount package (equivalent in footprint to size B tantalum capacitor), with dimensions 3.5 mm × 2.8 mm × 1.75 mm and non-diffused lens. Pin identification follows standard PLCC-2 polarity: cathode marked by notch or bevel on package edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current-limiting resistor and supply rail; must be biased ≥1.7 V above cathode to emit light |
| Cathode (K) | Negative terminal | Typically tied to ground or sink driver; polarity marking on package aids automated placement verification |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables efficient coupling into light pipes and directional backlighting without optical loss from diffusion layers |
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 per reel ensures consistent brightness across all units on a single tape - critical for uniform panel appearance |
| Solder process compatibility | Qualified for infrared reflow (J-STD-020 Level 2a), vapor phase, and wave soldering - supports high-yield SMT assembly |
| Low profile package | 1.75 mm height allows integration beneath thin bezels and in ultra-low-profile consumer interfaces |
| Thermal resistance | 500 K/W junction-to-ambient (on ≥16 mm² pad) enables stable operation up to +100 °C ambient without active cooling |
Applications
| Telecom Indicator | Audio/Video Backlight |
|---|---|
Use Scenario: Status indication on telephone handsets and fax machine control panels under variable ambient lighting. IC Role / Device Role / Timing Role: Discrete red LED emitter providing human-visible status feedback without microcontroller GPIO overhead. Use Value: Low 2 mA drive current extends battery life in cordless handsets; ±60° viewing angle ensures visibility across wide user angles. |
Use Scenario: Symbol illumination behind membrane switches on AV receivers and DVD players. IC Role / Device Role / Timing Role: Passive optical source driven directly from logic-level outputs or dedicated LED drivers. Use Value: Non-diffused lens couples efficiently into molded light guides; tight wavelength binning maintains consistent red hue across product batches. |
| Battery-Powered Indicator | LCD Flat Backlight |
Use Scenario: Power-on and mode indicators in portable medical monitors and handheld test equipment. IC Role / Device Role / Timing Role: Low-power visible emitter replacing higher-current LEDs to reduce quiescent load on coin-cell or Li-ion supplies. Use Value: 7 mA absolute max rating and 20 mW power dissipation allow direct drive from LDO outputs without thermal derating. |
Use Scenario: Edge-lit backlight for small character LCDs in office equipment and industrial HMI panels. IC Role / Device Role / Timing Role: Discrete red LED positioned at LCD perimeter to inject light into light-guide film. Use Value: 3.5 mm × 2.8 mm PLCC-2 footprint fits narrow bezel constraints; clear epoxy fill maximizes light extraction efficiency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar low-current red SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMY3100-GS08 | Yellow variant (λd = 585–595 nm); identical PLCC-2 package, 2 mA test condition, same luminous intensity range and viewing angle | Used where color differentiation is required (e.g., warning vs. ready states); not spectrally interchangeable with VLMT3100-GS08 | Select VLMY3100-GS08 only when yellow emission is functionally required; mechanical and electrical compatibility is maintained |
| TLDR6400 | Red LED in 0805 package (2.0 mm × 1.25 mm); higher typical intensity (2.5 mcd @ 20 mA) but requires 20 mA drive and has narrower ±30° viewing angle | Higher brightness suits outdoor-readable indicators; incompatible footprint and thermal profile prevent drop-in replacement | Choose TLDR6400 only if higher intensity justifies redesign for 0805 layout and increased power budget |
Compared with VLMT3100-GS08, VLMY3100-GS08 offers identical form-factor and drive conditions but shifts output to yellow for multi-color coding, while TLDR6400 trades package size and viewing angle for higher intensity at significantly higher current - neither is pin-compatible, but both serve adjacent low-current indicator roles.

FAQ
What is the maximum continuous forward current for VLMT3100-GS08?
The VLMT3100-GS08 has an absolute maximum DC forward current of 7 mA at ambient temperatures ≤90 °C. Exceeding this value risks accelerated degradation and reduced lifetime. Derating is required above 90 °C ambient, and pulse operation (e.g., multiplexed displays) may use higher peak currents within specified surge limits.
Does VLMT3100-GS08 support reflow soldering, and what profile should be used?
Yes, VLMT3100-GS08 is qualified for lead-free reflow soldering per J-STD-020 Level 2a. The recommended profile features peak temperature ≤260 °C for ≤10 seconds, ramp rates ≤3 °C/s (up) and ≤6 °C/s (down), and time above 217 °C limited to ≤30 seconds. Preconditioning per JEDEC Level 2a is required before reflow.
What does the "GS08" suffix indicate in VLMT3100-GS08?
The "GS08" suffix denotes Vishay's standard 8 mm antistatic blister tape packaging option containing 1500 units per reel. This format is optimized for automatic pick-and-place equipment and complies with DIN IEC 40 (CO) 564. Tape dimensions and reel specifications are documented in the official datasheet Figure 8 and Figure 9.
Is VLMT3100-GS08 RoHS and halogen-free compliant?
Yes, VLMT3100-GS08 is RoHS-compliant and halogen-free, meeting Vishay's material categorization standards per document 99912. Environmental compliance symbols (RoHS, Pb-free, halogen-free) appear on the standard bar code label affixed to each dry-packed reel.
How is luminous intensity binned for VLMT3100-GS08, and why does it matter?
VLMT3100-GS08 is binned by luminous intensity into groups C1–G2 (e.g., C1 = 0.28–0.36 mcd), with IVmax/IVmin ≤ 1.6 per reel. This ensures brightness consistency across all units on a single tape - essential for uniform appearance in multi-LED panels and avoids post-assembly sorting or calibration.
