Product details
Overview
VLMY33T1U2-GS08 from Vishay Semiconductors is a surface-mount yellow power LED in PLCC-2 package, designed for 30 mA DC operation with dominant wavelength 583–594 nm, luminous intensity 280–710 mcd, and forward voltage 1.7–2.5 V. It delivers high-brightness indicator and backlighting performance in automotive dashboards, signage, and consumer interface panels.
For engineers reviewing the VLMY33T1U2-GS08 datasheet, VLMY33T1U2-GS08 pinout, VLMY33T1U2-GS08 application, or VLMY33T1U2-GS08 equivalent, key selection criteria include its AEC-Q101 qualification, ±60° viewing angle, 400 K/W thermal resistance, JESD22-A114-B ESD rating (2 kV), and compatibility with reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802.
Technical Context
The VLMY33T1U2-GS08 uses AlInGaP-on-GaAs die technology to achieve stable yellow emission with narrow spectral bandwidth (Δλ ≤ 18 nm) and minimal dominant wavelength shift over temperature (±6 nm from −50 °C to +100 °C). Its PLCC-2 package integrates a white thermoplastic lead frame and clear epoxy lens, enabling uniform angular distribution and high reflectivity.
Rated for 50 mA maximum forward current at Tamb ≤ 73 °C and junction temperature up to +125 °C, it supports continuous operation in industrial and automotive ambient ranges (−40 °C to +100 °C) with thermal resistance of 400 K/W when mounted on ≥16 mm² PCB copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Color | Yellow - defined by dominant wavelength 583–594 nm, suitable for high-visibility status indication where amber/yellow coding is required. |
| Luminous intensity | 280–710 mcd at 30 mA - enables flexible brightness binning (Group U) without mixing bins per reel, supporting consistent visual output across production batches. |
| Dominant wavelength | 583–594 nm - tightly binned per JEDEC-compliant color classification (Groups 2–6), ensuring color consistency in multi-LED arrays. |
| Forward voltage | 1.7–2.5 V at 30 mA - low VF range simplifies drive circuit design and reduces power loss in series-string or constant-current configurations. |
| Viewing angle | ±60° - wide Lambertian radiation pattern provides broad, uniform illumination for panel backlighting and symbol lighting applications. |
| Thermal resistance | 400 K/W - requires ≥16 mm² copper pad for thermal management; limits max. continuous current to 50 mA only below 73 °C ambient. |
| ESD rating | 2 kV HBM per JESD22-A114-B - sufficient for handling in standard assembly environments without specialized ESD controls beyond antistatic tape/reel packaging. |
Pinout & Package
Package: SMD PLCC-2 with 2-terminal configuration (anode/cathode), white thermoplastic body, clear epoxy lens, and integrated reflector. Dimensions per drawing 6.541-5067.01-4: 3.5 ± 0.2 mm length, 2.8 ± 0.15 mm width, 2.2 mm height, 0.9 mm terminal thickness, and 1.75 ± 0.1 mm terminal pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive DC input | Connected to constant-current source or current-limiting resistor; polarity must be observed to avoid reverse breakdown (VR = 5 V max). |
| Cathode (K) | Ground return path | Serves as thermal and electrical reference; PCB pad layout must provide ≥16 mm² copper area for thermal dissipation per RthJA = 400 K/W spec. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMS33S1U1-GS08 | Super red (626–638 nm), same PLCC-2 package, identical IV range (180–560 mcd), but higher VF min (1.7 V) and wider λd tolerance. | Used where red coding is required (e.g., error alerts); not interchangeable for yellow-specific signaling due to CIE chromaticity mismatch. | Select only when red emission is mandated; cannot substitute for yellow-coded safety or status functions. |
| VLMR33T1U2-GS08 | Orange red (611–622 nm), same package and IV range (280–710 mcd), but shorter dominant wavelength and higher spectral irradiance at 620 nm. | Preferred for high-contrast stop-light or caution indicators where orange-red offers better daylight visibility than yellow. | Choose for applications needing higher photopic luminance in bright ambient conditions; not suitable where yellow chromaticity is specified (e.g., ISO 3864-1). |

FAQ
What is the maximum continuous forward current for VLMY33T1U2-GS08?
The VLMY33T1U2-GS08 supports 50 mA DC forward current only when ambient temperature remains ≤73 °C, as specified in Absolute Maximum Ratings. At higher temperatures, derating is required per Fig. 1 (Forward Current vs. Ambient Temperature), with zero permissible current above +100 °C ambient. The 30 mA test condition used in optical specs reflects typical operating point for luminous intensity and wavelength characterization.
Is VLMY33T1U2-GS08 compatible with lead-free reflow soldering processes?
Yes, VLMY33T1U2-GS08 is qualified for lead-free reflow per J-STD-020, with a maximum peak package body temperature of 260 °C for ≤10 seconds. The recommended profile (Fig. 26) specifies ramp-up ≤3 °C/s, time above 217 °C ≤30 s, and peak hold at 240–245 °C. It also supports vapor-phase and wave soldering per CECC 00802.
Does VLMY33T1U2-GS08 have built-in current regulation or driver circuitry?
No, VLMY33T1U2-GS08 is a passive two-terminal LED device with no integrated driver, current regulator, or control logic. It requires an external constant-current source or appropriate series resistor to limit forward current to ≤50 mA. All electrical and optical parameters assume externally controlled bias conditions.
What does the "U2" suffix in VLMY33T1U2-GS08 indicate?
The "U2" suffix denotes luminous intensity bin U (450–710 mcd) and color bin 2 (dominant wavelength 583–586 nm), per the COLOR CLASSIFICATION table. Each reel ships with LEDs from a single intensity and wavelength group - no mixing - ensuring consistent optical performance across the full 1500-piece reel.
Can VLMY33T1U2-GS08 be used in reverse-bias configurations?
No - the VLMY33T1U2-GS08 is not rated for reverse conduction. Absolute maximum reverse voltage is 5 V (note 1 states reverse operation is "suitable for short term application", but this refers to transient reverse pulses during AC drive or multiplexed scanning, not sustained reverse bias). Exceeding 5 V reverse risks permanent junction damage.
