Product details
Overview
VLMY333U1AA-GS08 from Vishay Semiconductors is a yellow surface-mount power LED in PLCC-2 package, rated for 50 mA DC forward current, with dominant wavelength 583–594 nm, luminous intensity 450–1400 mcd at 20 mA, and forward voltage 1.8–2.6 V - used in indicator, backlighting, and dashboard illumination systems.
For engineers reviewing the VLMY333U1AA-GS08 datasheet, VLMY333U1AA-GS08 pinout, VLMY333U1AA-GS08 application, or VLMY333U1AA-GS08 equivalent, key selection criteria include dominant wavelength tolerance, thermal resistance (400 K/W), AEC-Q101 qualification, ±60° viewing angle, and compatibility with reflow soldering per J-STD-020.
Technical Context
The VLMY333U1AA-GS08 uses AlInGaP-on-Si technology to deliver stable yellow emission with peak wavelength at 591 nm and spectral bandwidth of 17 nm at 50% relative intensity. Its PLCC-2 package features a white thermoplastic lead frame and clear epoxy-filled reflector, enabling high thermal dissipation and directional light output.
Rated for operation from –40 °C to +100 °C ambient, it supports up to 50 mA drive current when mounted on PCBs with pad area >16 mm², and exhibits reverse voltage tolerance of 5 V for short-term applications. ESD withstand voltage is 2 kV per JESD22-A114-B.
Key Specifications
| Parameter | Value and Actual Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMO333U2AB-GS08 | Soft orange emission (600–611 nm), higher typical luminous intensity (950 mcd), same PLCC-2 package and drive specs | Used where warmer amber tone is preferred over yellow - e.g., decorative lighting or non-regulatory signage | Select when chromaticity must shift toward orange while retaining mechanical and thermal compatibility |
| LY T67F-U1AA-36-1 | OSRAM cross-reference; identical dominant wavelength (583–594 nm), same intensity bin (U1AA), but different thermal resistance (420 K/W) | Drop-in alternative only if board layout accommodates slightly higher junction temperature rise | Choose for multi-source procurement where OSRAM supply chain preference applies; verify thermal margin in final layout |
Compared with VLMY333U1AA-GS08, VLMO333U2AB-GS08 shifts chromaticity toward orange without altering drive or thermal design, while LY T67F-U1AA-36-1 offers second-source availability with minor thermal derating - both require validation of optical and thermal behavior in target application.

FAQ
What is the maximum continuous forward current for VLMY333U1AA-GS08?
The VLMY333U1AA-GS08 supports a maximum DC forward current of 50 mA when ambient temperature is ≤73 °C and mounted on a PCB with thermal pad area >16 mm². At higher temperatures, derating per Fig. 1 in the datasheet applies - e.g., 35 mA at 100 °C ambient. Exceeding this limit risks accelerated lumen depreciation and junction overheating.
Is VLMY333U1AA-GS08 suitable for automotive applications?
Yes, VLMY333U1AA-GS08 is AEC-Q101 qualified, meaning it has passed stress tests for temperature cycling, humidity, mechanical shock, and ESD required for automotive electronic components. It is commonly deployed in dashboard illumination and exterior indicator systems where reliability under thermal and vibration stress is critical.
What does the "U1AA" suffix indicate in VLMY333U1AA-GS08?
In VLMY333U1AA-GS08, "U1AA" denotes the luminous intensity and dominant wavelength bin: "U" = 450–560 mcd intensity group, "1" = first sub-bin within U, and "AA" = dominant wavelength group covering 583–586 nm. This binning ensures consistent optical performance across reels shipped to a single customer order.
Can VLMY333U1AA-GS08 be soldered using standard lead-free reflow profiles?
Yes, VLMY333U1AA-GS08 is qualified for lead-free reflow per J-STD-020, with a maximum peak temperature of 260 °C for ≤10 s. The recommended profile (Fig. 13) specifies ramp rates ≤3 °C/s, time above 217 °C ≤60 s, and dwell at peak ≤120 s - fully compatible with standard Class 3 assembly lines.
What is the viewing angle specification for VLMY333U1AA-GS08, and how is it measured?
VLMY333U1AA-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 is measured per CIE 127:2007 at 20 mA DC drive, defining the usable beam width for uniform panel illumination and indicator visibility.
