Product details
Overview
VLMS334AABB-GS08 from Vishay Semiconductors is a surface-mount super red power LED in PLCC-2 package, rated for 70 mA DC forward current, with dominant wavelength 626–639 nm, luminous intensity 1120–2800 mcd at 50 mA, and thermal resistance 300 K/W - used in high-reliability dashboard illumination and traffic signal indicators.
For engineers reviewing the VLMS334AABB-GS08 datasheet, VLMS334AABB-GS08 pinout, VLMS334AABB-GS08 application, or VLMS334AABB-GS08 equivalent, this page delivers verified optical, electrical, and packaging data - including AEC-Q101 qualification, ±60° viewing angle, AlInGaP-on-Si technology, JEDEC level 2a preconditioning, and reflow-compatible PLCC-2 footprint - to support automotive-grade lighting design and BOM validation.
Technical Context
This super red LED uses AlInGaP-on-Si die technology to achieve high radiant efficiency and stable chromaticity across temperature. Its PLCC-2 package integrates a white thermoplastic lead frame and clear epoxy-filled reflector, enabling uniform light extraction and mechanical robustness under thermal cycling.
Designed for continuous operation up to 125 °C junction temperature and rated for -40 to +100 °C ambient range, VLMS334AABB-GS08 supports automotive and industrial applications requiring AEC-Q101 compliance, ESD tolerance up to 2 kV (JESD22-A114-B), and compatibility with CECC 00802 and J-STD-020 soldering processes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 1120–2800 mcd at 50 mA - defines brightness binning for consistent visual output across production reels |
| Dominant wavelength | 626–639 nm - ensures super red chromaticity compliant with traffic signal and automotive indicator standards |
| Forward voltage | 1.9–2.8 V at 50 mA - enables low-voltage drive compatibility with 3.3 V and 5 V logic-supplied LED drivers |
| Viewing angle | ±60° - provides wide beam pattern suitable for panel backlighting and symbol illumination without secondary optics |
| Thermal resistance | 300 K/W - requires ≥16 mm² copper pad for thermal management at 70 mA continuous operation |
| ESD rating | 2 kV HBM - meets IEC 61000-4-2 Level 3 for handling in non-ESD-controlled assembly environments |
| AEC-Q101 | Qualified - validated for automotive under-hood and cabin lighting per stress test requirements |
Pinout & Package
VLMS334AABB-GS08 uses a 2-pin PLCC-2 surface-mount package with cathode-anode polarity marked by a notch on the package top edge. The lead frame is embedded in white thermoplastic, and the reflector cavity is filled with clear epoxy for optimal light coupling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current source; must be driven through series resistor or constant-current driver to limit IF ≤ 70 mA |
| Cathode (K) | Negative terminal | Connected to ground or low-side switch; polarity reversal permitted only for short-term testing per datasheet note (1) |
Key Features
| Feature | Design Value |
|---|---|
| AlInGaP-on-Si die technology | Delivers high luminous efficacy and wavelength stability over temperature vs. traditional GaAsP |
| PLCC-2 with white thermoplastic body | Enables high reflectivity (>90%) and thermal-mechanical reliability during reflow and thermal cycling |
| Luminous intensity ratio ≤ 1.6 | Ensures tight brightness matching within each tape reel (IVmax/IVmin ≤ 1.6) for uniform appearance in multi-LED arrays |
| AEC-Q101 qualification | Validates suitability for automotive interior lighting, including instrument cluster and switch backlighting |
| JEDEC level 2a preconditioning | Confirms moisture sensitivity level (MSL) 2a compliance - allows 672-hour factory floor exposure before reflow |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LS T67F-T2V2-1-1 | OSRAM equivalent; same PLCC-2 package, 625–635 nm dominant wavelength, 1200–2600 mcd at 50 mA | Identical use in traffic signals and automotive indicators; slightly tighter wavelength binning | Select when sourcing from OSRAM-dedicated supply chains or requiring cross-manufacturer second-source validation |
| VLMR334BACB-GS08 | Vishay red variant (619–631 nm); higher typical luminous intensity (2200 mcd vs. 1600 mcd) but narrower red chromaticity | Better suited for general-purpose red indicators where super red's longer wavelength is not mandated | Choose for cost-sensitive non-regulatory applications where chromaticity tolerance is relaxed and higher brightness is prioritized |
Compared with VLMS334AABB-GS08, LS T67F-T2V2-1-1 offers matched optical specs and direct drop-in replacement capability in PLCC-2 layout, while VLMR334BACB-GS08 trades super red chromaticity for higher nominal output - making it suitable where regulatory red hue compliance is not required.

FAQ
What is the maximum continuous forward current rating for VLMS334AABB-GS08?
The VLMS334AABB-GS08 is rated for 70 mA DC forward current at ambient temperatures ≤ 65 °C with a thermal resistance of 300 K/W and ≥16 mm² PCB copper pad. Exceeding this current without adequate thermal management reduces lifetime and risks catastrophic failure. Derating is required above 65 °C per Figure 1 in the datasheet.
Is VLMS334AABB-GS08 qualified for automotive applications?
Yes, VLMS334AABB-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive under-hood and cabin lighting. It is commonly used in instrument cluster backlighting and status indicators where reliability under thermal and vibration stress is critical.
What does the "GS08" suffix indicate in VLMS334AABB-GS08?
The "GS08" suffix denotes Vishay's standard 8 mm antistatic blister tape packaging option containing 1500 pieces per reel. This format is compatible with automated pick-and-place equipment and conforms to DIN IEC 40 (CO) 564. GS08 also implies JEDEC level 2a moisture sensitivity and dry-pack shipping with desiccant and humidity indicator card.
Can VLMS334AABB-GS08 be used in reverse-bias configuration?
The datasheet permits short-term reverse voltage application (≤5 V) for testing purposes only, as noted in the Absolute Maximum Ratings table. Continuous or repeated reverse bias is not recommended, as it may degrade the AlInGaP die or cause irreversible leakage current increase. VLMS334AABB-GS08 is designed for forward conduction only.
What is the viewing angle specification for VLMS334AABB-GS08 and how is it measured?
VLMS334AABB-GS08 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50% of its peak value at 60° off-axis in both directions. This is measured at 50 mA forward current under standard conditions (Tamb = 25 °C) using angular photometry per CIE 127, and is confirmed in Figure 2 of the datasheet.
