Product details
Overview
VLMO33T1U2-GS08 from Vishay Semiconductors is a surface-mount orange-red power LED in PLCC-2 package, featuring 450 mcd typical luminous intensity at 30 mA, 617 nm typical dominant wavelength, ±60° viewing angle, and 400 K/W thermal resistance. It delivers high-brightness indicator lighting for automotive dashboard illumination and traffic signal modules.
For engineers reviewing the VLMO33T1U2-GS08 datasheet, VLMO33T1U2-GS08 pinout, VLMO33T1U2-GS08 application, or VLMO33T1U2-GS08 equivalent, key selection criteria include luminous intensity binning (U-group), AEC-Q101 qualification, AlInGaP-on-GaAs chip technology, reflow-compatible PLCC-2 footprint, and JEDEC level 2a moisture sensitivity handling.
Technical Context
The VLMO33T1U2-GS08 uses AlInGaP-on-GaAs semiconductor technology to achieve stable orange-red emission with 611–622 nm dominant wavelength range and 18 nm spectral bandwidth. Its PLCC-2 package integrates a white thermoplastic lead frame and clear epoxy lens, enabling ±60° Lambertian radiation pattern and 3 mlm/mcd luminous flux-to-intensity ratio.
Rated for 50 mA DC forward current at ambient temperatures ≤73 °C, it maintains operation across –40 °C to +100 °C ambient range with 125 °C maximum junction temperature. Thermal resistance is fixed at 400 K/W when mounted on PCB pads >16 mm², and ESD withstand voltage reaches 2 kV per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 280–710 mcd at 30 mA (U-group binning ensures tight intensity matching within reel) |
| Dominant wavelength | 611–622 nm (orange-red chromaticity suitable for high-visibility signaling) |
| Forward voltage | 1.7–2.5 V at 30 mA (low VF enables efficient drive with 3.3 V or 5 V logic-level sources) |
| Viewing angle | ±60° (wide beam supports uniform illumination across control panel symbols) |
| Thermal resistance | 400 K/W (requires ≥16 mm² copper pad for sustained 50 mA operation) |
| ESD rating | 2 kV HBM (robust handling during automated SMT assembly without special grounding) |
| AEC-Q101 | Qualified (validates reliability for automotive interior lighting and instrument cluster use) |
Pinout & Package
VLMO33T1U2-GS08 uses a 2-pin PLCC-2 surface-mount package with molded white thermoplastic body and clear epoxy lens. Pin 1 (anode) and Pin 2 (cathode) are identified by physical notch orientation and tape feed direction per DIN IEC 40 (CO) 564 blister tape standard.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Positive terminal; must connect to current-limiting resistor or constant-current driver output |
| Pin 2 | Cathode | Ground reference; ties to system GND or driver return path; polarity-sensitive for reverse-voltage protection |
Key Features
| Feature | Design Value |
|---|---|
| AlInGaP-on-GaAs chip technology | Delivers high radiant efficiency and stable orange-red output with minimal wavelength shift over temperature (±1.5 nm from –40 °C to +100 °C) |
| Luminous intensity ratio ≤1.6 | Ensures consistent brightness across units in same reel (IVmax/IVmin ≤ 1.6), critical for uniform backlighting in multi-LED arrays |
| JEDEC level 2a preconditioning | Enables standard reflow soldering without baking unless exposed >672 h at >30 °C/60 % RH after bag opening |
| Reflow/vapor-phase/wave solder compatible | Withstands peak reflow temperatures up to 260 °C per J-STD-020, supporting high-volume automated assembly |
| AEC-Q101 qualification | Validates robustness against thermal cycling, humidity bias, and mechanical shock required for automotive cabin applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR33T1U2-GS08 | Identical optical/electrical specs and package; same Vishay part number prefix and U2 binning - confirmed identical device | No functional difference; both rated for traffic, automotive, and industrial indicator use | Select based on distributor stock availability; GS08 (1500/reel) suits prototyping and low-volume production |
| TLMO33T1U2 | Same PLCC-2 package, ±60° viewing angle, and 611–622 nm dominant wavelength, but lower 350 mcd max intensity and no AEC-Q101 qualification | Suitable for non-automotive industrial panels where qualification is not mandated | Choose VLMO33T1U2-GS08 when automotive-grade reliability or higher intensity consistency is required |
Compared with VLMR33T1U2-GS08 (identical specification) and TLMO33T1U2 (lower intensity, no AEC-Q101), VLMO33T1U2-GS08 offers guaranteed U-group luminous intensity binning and full automotive qualification-making it the preferred choice for safety-critical or high-reliability orange-red indicator applications.

FAQ
What is the maximum continuous forward current rating for VLMO33T1U2-GS08?
The VLMO33T1U2-GS08 is rated for 50 mA DC forward current when ambient temperature remains ≤73 °C. Exceeding this limit without thermal derating risks junction temperature exceeding 125 °C, accelerating lumen depreciation. At 30 mA, the device operates well within safe margins and delivers its specified 450 mcd typical luminous intensity.
Does VLMO33T1U2-GS08 require baking before reflow soldering?
VLMO33T1U2-GS08 is preconditioned to JEDEC level 2a and shipped in dry-packed anti-humidity bags. Baking is only required if the sealed bag has been opened and the reel exposed to >30 °C/60 % RH for more than 672 hours. Otherwise, standard J-STD-020 reflow profiles (peak 260 °C) may be applied directly.
Is VLMO33T1U2-GS08 pin-compatible with other PLCC-2 LEDs from Vishay?
Yes - VLMO33T1U2-GS08 shares the standardized 2-pin PLCC-2 footprint, pad layout, and polarity marking (notch-aligned anode) with all VLM.33.. series devices including VLMS33S1T2-GS08 and VLMY33T1U2-GS08. This enables drop-in replacement within the same package family when optical parameters align with design requirements.
What does the "U2" suffix indicate in VLMO33T1U2-GS08?
The "U2" suffix denotes luminous intensity binning per Vishay's classification table: U-group covers 450–710 mcd at 30 mA, and "2" specifies the upper sub-bin (560–710 mcd). This ensures narrow intensity distribution within each reel, critical for uniform appearance in multi-LED applications like dashboard backlighting.
Can VLMO33T1U2-GS08 be driven directly from a 3.3 V microcontroller GPIO?
Yes - with a properly sized series current-limiting resistor. At 30 mA drive and 2.0 V typical forward voltage, a 43 Ω resistor yields ~3.3 V – 2.0 V = 1.3 V drop, resulting in 30.2 mA. Ensure GPIO can sink/supply ≥30 mA continuously and verify thermal dissipation on the PCB pad to maintain RthJA ≤ 400 K/W.
