Product details
Overview
VLMR33T1U2-GS08 from Vishay Semiconductors is an orange-red power SMD LED in PLCC-2 package, rated for 50 mA DC forward current, with dominant wavelength 611–622 nm, luminous intensity 280–710 mcd at 30 mA, and forward voltage 1.7–2.5 V - used in automotive dashboard illumination and traffic signal indicators.
For engineers reviewing the VLMR33T1U2-GS08 datasheet, VLMR33T1U2-GS08 pinout, VLMR33T1U2-GS08 application, or VLMR33T1U2-GS08 equivalent, key selection criteria include luminous intensity binning (U-group), ±60° viewing angle, AEC-Q101 qualification, thermal resistance of 400 K/W, and compatibility with lead-free reflow per J-STD-020.
Technical Context
The VLMR33T1U2-GS08 uses AlInGaP-on-GaAs technology to deliver stable orange-red emission with peak wavelength at 624 nm and spectral bandwidth of 18 nm at 50% relative intensity. Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and integrated reflector.
Designed for high-reliability industrial and automotive use, it supports JEDEC level 2a preconditioning, withstands 2 kV ESD (JESD22-A114-B), and operates across –40 °C to +100 °C ambient temperature with junction limit of +125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 280–710 mcd at 30 mA - defines brightness binning (U-group) for consistent visual output across production reels |
| Dominant wavelength | 611–622 nm - ensures precise orange-red chromaticity compliant with traffic signal and automotive color standards |
| Forward voltage | 1.7–2.5 V at 30 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 indicator backlighting and surface-mounted status lighting |
| Thermal resistance | 400 K/W - requires ≥16 mm² copper pad for thermal management at 50 mA continuous operation |
| ESD rating | 2 kV HBM - meets industrial handling requirements without additional on-board protection circuitry |
| AEC-Q101 | Qualified - validated for automotive under-hood and cabin applications including dashboard illumination |
Pinout & Package
PLCC-2 package: 2-pin surface-mount device with cathode (pin 1) and anode (pin 2) terminals; molded white thermoplastic body (3.5 mm × 2.8 mm × 2.2 mm), clear epoxy lens, and internal reflector structure. Mounting pad layout requires solder mask opening per Vishay drawing 6.541-5067.01-4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Cathode | Connected to ground or current-sink driver; polarity must be observed to avoid reverse-bias damage beyond 5 V |
| Pin 2 | Anode | Connected to bias voltage or current-source driver; forward conduction begins at ~1.7 V threshold |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity testing, and mechanical shock |
| Luminous intensity ratio ≤ 1.6 | Ensures tight brightness consistency (IVmax/IVmin) within each 1500-piece GS08 reel |
| Reflow-compatible packaging | Rated for Pb-free reflow up to 260 °C peak, vapor phase, and wave solder per CECC 00802 and J-STD-020 |
| JEDEC level 2a preconditioning | Enables safe handling and assembly without moisture sensitivity concerns when unsealed ≤672 h at ≤30 °C/60% RH |
| AlInGaP-on-GaAs chip technology | Delivers high radiant efficiency and wavelength stability over temperature vs. traditional GaAsP LEDs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMS33S1U1-GS08 | Super red emission (626–638 nm), lower min. luminous intensity (180 mcd) | Better suited for high-contrast red signaling where longer wavelength improves photopic visibility | Select when color point must shift toward standard red; not interchangeable for orange-red compliance-critical uses |
| VLMY33T1U2-GS08 | Yellow emission (583–594 nm), same U-group intensity binning and PLCC-2 package | Used where amber/yellow chromaticity required (e.g., turn signals, caution indicators) | Drop-in physical replacement but optically distinct; verify spectral match before substitution |
Compared with VLMR33T1U2-GS08, VLMS33S1U1-GS08 shifts dominant wavelength +15 nm for deeper red compliance, while VLMY33T1U2-GS08 moves –28 nm to yellow - both retain identical thermal, electrical, and mechanical specs, enabling board-level reuse only when chromaticity permits.

FAQ
What is the maximum continuous forward current rating for VLMR33T1U2-GS08?
The VLMR33T1U2-GS08 is rated for 50 mA DC forward current at ambient temperatures ≤73 °C when mounted on a PCB with thermal pad area >16 mm². Exceeding this current without adequate thermal management reduces lifetime and risks thermal runaway. Derating is required above 73 °C per Fig. 1 in the datasheet.
Is VLMR33T1U2-GS08 suitable for automotive applications?
Yes, VLMR33T1U2-GS08 is AEC-Q101 qualified and tested for automotive use including temperature cycling, humidity exposure, and mechanical shock. It is deployed in dashboard illumination, interior lighting, and exterior indicator systems where orange-red chromaticity and long-term reliability are critical.
What does the "U2" suffix indicate in VLMR33T1U2-GS08?
The "U2" suffix denotes the luminous intensity bin: U-group (450–710 mcd at 30 mA) and sub-bin 2 (upper half of that range). This ensures consistent brightness across all units on a given 1500-piece GS08 reel, eliminating mixing of intensity groups per Vishay's packing policy.
Can VLMR33T1U2-GS08 be soldered using standard lead-free reflow profiles?
Yes, VLMR33T1U2-GS08 is qualified for Pb-free reflow per J-STD-020, with peak temperature up to 260 °C for ≤10 seconds. The recommended profile (Fig. 26) specifies ramp rates ≤3 °C/s, time above 217 °C ≤30 s, and cooling rate ≤6 °C/s to prevent package cracking or delamination.
What is the viewing angle specification for VLMR33T1U2-GS08?
VLMR33T1U2-GS08 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50% of its axial value at 60° off-center in both horizontal and vertical planes. This wide viewing angle supports uniform illumination across broad surfaces without secondary optics.
