Product details
Overview
VLMR33R2U2-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 thermal resistance 400 K/W - deployed in traffic signal indicators and automotive dashboard illumination.
For engineers reviewing the VLMR33R2U2-GS08 datasheet, VLMR33R2U2-GS08 pinout, VLMR33R2U2-GS08 application, or VLMR33R2U2-GS08 equivalent, key selection criteria include its AEC-Q101 qualification, ±60° viewing angle, JESD22-A114-B ESD rating (2 kV), JEDEC level 2a preconditioning compliance, and reflow/wave solder compatibility per J-STD-020 and CECC 00802.
Technical Context
This device uses AlInGaP-on-GaAs chip technology to deliver stable orange-red emission under high-current operation. Its PLCC-2 thermoplastic package embeds a lead frame with white reflector cavity filled with clear epoxy, enabling efficient light extraction and thermal management up to +125 °C junction temperature.
Rated for 50 mA continuous drive at ambient ≤73 °C, it maintains luminous output across -40 to +100 °C operating range with forward voltage 1.7–2.5 V at 30 mA and reverse voltage limit of 5 V. Spectral bandwidth is 18 nm at 50% relative intensity, with dominant wavelength shift <±1.5 nm over 10–90 mA drive range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 | Same series, identical optical specs (611–622 nm, 280–710 mcd), but categorized in different luminous intensity bin (U2 vs R2) | Matches same physical footprint and drive requirements; differs only in pre-binned brightness group | Select when tighter luminance matching within U-bin is required for specific display uniformity targets |
| TLMO1100F1000 | OSRAM PLCC-2 orange-red LED; dominant wavelength 610–620 nm, 250–630 mcd at 30 mA, RthJA = 420 K/W | Slightly lower max intensity and higher thermal resistance; JEDEC level 2a compliant but not AEC-Q101 qualified | Choose for non-automotive industrial use where AEC-Q101 is not mandated and cost sensitivity outweighs binning precision |
Compared with VLMR33R2U2-GS08, VLMR33T1U2-GS08 offers identical photometric performance in a different brightness bin, while TLMO1100F1000 provides cross-brand compatibility at marginally reduced intensity and thermal efficiency - making the former ideal for brightness-matched replacements and the latter suitable for cost-driven non-automotive designs.

FAQ
What is the maximum continuous forward current rating for VLMR33R2U2-GS08?
The VLMR33R2U2-GS08 is rated for 50 mA DC forward current at ambient temperatures ≤73 °C. Exceeding this current without thermal derating risks junction temperature exceeding +125 °C, accelerating lumen depreciation and reducing lifetime. The 400 K/W thermal resistance requires adequate PCB copper area (>16 mm²) to maintain safe operation.
Is VLMR33R2U2-GS08 qualified for automotive applications?
Yes, VLMR33R2U2-GS08 is AEC-Q101 qualified, meaning it has passed accelerated stress tests including temperature cycling, humidity bias, mechanical shock, and ESD per JESD22-A114-B. This qualification validates its suitability for under-hood and cabin-mounted automotive lighting functions such as dashboard indicators and warning lamps.
What does the "U2" suffix indicate in VLMR33R2U2-GS08?
The "U2" suffix denotes the luminous intensity bin 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 consistent brightness within each 1500-piece GS08 tape reel, with no mixing of intensity groups - critical for uniform appearance in multi-LED displays.
Can VLMR33R2U2-GS08 be used in reverse-bias configuration?
The datasheet notes that reverse-direction driving is suitable only for short-term applications. VLMR33R2U2-GS08 has a maximum reverse voltage rating of 5 V; prolonged reverse bias may cause irreversible degradation of the AlInGaP/GaAs junction. It is not designed as a bidirectional device and should be operated exclusively in forward bias for reliable performance.
What soldering processes are validated for VLMR33R2U2-GS08?
VLMR33R2U2-GS08 is validated for Pb-free reflow (J-STD-020), vapor-phase, and wave soldering (CECC 00802). Its peak reflow temperature tolerance is 260 °C for ≤10 s, with ramp rates limited to 3 °C/s (up) and 6 °C/s (down). Preconditioning per JEDEC level 2a ensures moisture sensitivity is managed without mandatory baking if mounted within 672 hours of bag opening.
