Product details
Overview
VLMY33T2U2-GS08 from Vishay Semiconductors is a surface-mount yellow power LED in PLCC-2 package, built with AlInGaP-on-GaAs technology, delivering 280–425 mcd luminous intensity at 30 mA, 583–594 nm dominant wavelength, and ±60° viewing angle - deployed in automotive dashboard illumination and industrial indicator lighting.
For engineers reviewing the VLMY33T2U2-GS08 datasheet, VLMY33T2U2-GS08 pinout, VLMY33T2U2-GS08 application, or VLMY33T2U2-GS08 equivalent, key selection criteria include luminous intensity binning (Group T/U), thermal resistance (400 K/W), AEC-Q101 qualification, and compatibility with JEDEC Level 2a reflow profiles.
Technical Context
The VLMY33T2U2-GS08 uses AlInGaP-on-GaAs chip technology to achieve stable yellow emission with narrow spectral bandwidth (Δλ ≤ 18 nm) and low forward voltage drift over temperature (±250 mV from −50 °C to +100 °C). Its PLCC-2 thermoplastic package integrates a white reflector cavity filled with clear epoxy for high optical coupling efficiency.
Rated for 50 mA DC forward current at ambient temperatures ≤73 °C, it maintains luminous output across −40 °C to +100 °C operating range and withstands 2 kV ESD (HBM, JESD22-A114-B). Preconditioning per JEDEC Level 2a ensures robustness in automated SMT assembly.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMY33T1U2-GS08 | Identical package, same luminous intensity range (280–425 mcd), but narrower dominant wavelength bin (583–586 nm vs. 583–594 nm) | Suitable where tighter chromaticity control is required, e.g., color-matched multi-LED arrays | Select VLMY33T1U2-GS08 when binning consistency across production lots is prioritized over maximum intensity flexibility |
| TLHY5100 | PLCC-2 yellow LED (590 nm typ.), 200–350 mcd at 20 mA, higher VF (2.1–2.6 V), non-AEC-Q101 | Targeted at commercial-grade consumer electronics, not automotive or industrial harsh environments | Choose TLHY5100 only for cost-sensitive, non-automotive designs where AEC-Q101 and 50 mA drive capability are unnecessary |
Compared with VLMY33T2U2-GS08, VLMY33T1U2-GS08 offers tighter wavelength control but identical thermal and drive specs, while TLHY5100 trades AEC-Q101 compliance and higher current capability for lower cost and reduced intensity - making VLMY33T2U2-GS08 optimal for automotive and industrial applications demanding both reliability and brightness headroom.

FAQ
What is the maximum continuous forward current for VLMY33T2U2-GS08?
The VLMY33T2U2-GS08 supports 50 mA DC forward current when mounted on a PCB with pad area >16 mm² and ambient temperature ≤73 °C. Exceeding this limit without thermal derating risks junction temperature exceeding +125 °C, accelerating lumen depreciation. Always verify board layout thermal performance before operating VLMY33T2U2-GS08 at rated current.
Is VLMY33T2U2-GS08 compatible with lead-free reflow soldering?
Yes, VLMY33T2U2-GS08 is fully compatible with lead-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 s. The device undergoes JEDEC Level 2a preconditioning and passes CECC 00802 vapor-phase and wave solder validation - no special prebake is required if sealed dry bag storage guidelines are followed.
What does the "T2" suffix indicate in VLMY33T2U2-GS08?
The "T2" in VLMY33T2U2-GS08 denotes the luminous intensity bin group per Vishay's classification table: Group T corresponds to 280–355 mcd (minimum) and 355–450 mcd (maximum) at 30 mA. This binning ensures predictable brightness matching across reels used in multi-LED assemblies like instrument clusters or signage modules.
Does VLMY33T2U2-GS08 have polarity marking for automated placement?
Yes, VLMY33T2U2-GS08 features a chamfered corner on the PLCC-2 package that identifies the cathode (K) pin. This mechanical polarity marker is detectable by vision-guided pick-and-place systems and aligns with IPC-7351 standards for SMD LED orientation verification during high-speed assembly.
What is the storage lifetime of VLMY33T2U2-GS08 in its original dry pack?
VLMY33T2U2-GS08 has a shelf life of 12 months when stored in its original sealed aluminum moisture barrier bag at <40 °C and <90% RH. Once opened, devices must be mounted within 672 hours at ≤30 °C/60% RH or stored at <10% RH; otherwise, baking per J-STD-033 (e.g., 96 h at 60 °C/<5% RH) is required prior to reflow.
