Product details
Overview
VLMK333U2AB-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 560–1800 mcd at 20 mA, and forward voltage 1.8–2.6 V - deployed in automotive dashboard illumination and traffic signal indicators.
For engineers reviewing the VLMK333U2AB-GS08 datasheet, VLMK333U2AB-GS08 pinout, VLMK333U2AB-GS08 application, or VLMK333U2AB-GS08 equivalent, key selection criteria include luminous intensity binning (Group B), AEC-Q101 qualification, ±60° viewing angle, thermal resistance of 400 K/W, and compatibility with lead-free reflow soldering per J-STD-020.
Technical Context
The VLMK333U2AB-GS08 uses AlInGaP-on-Si die technology to deliver high-brightness orange-red emission with spectral bandwidth ≤18 nm at 50% relative intensity. Its PLCC-2 package features a white thermoplastic lead frame and clear epoxy-filled reflector, enabling stable optical output under thermal cycling.
Rated for operation from –40 °C to +100 °C ambient, it supports up to 50 mA drive at Tamb ≤ 73 °C (with RthJA = 400 K/W on ≥16 mm² PCB pad), and withstands 2 kV ESD per JESD22-A114-B - meeting JEDEC level 2a preconditioning and AEC-Q101 stress requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 560–1800 mcd at 20 mA - defines brightness binning (Group B) for consistent visual matching across units |
| Dominant wavelength | 611–622 nm - ensures precise orange-red chromaticity for color-critical signaling applications |
| Forward voltage | 1.8–2.6 V at 20 mA - determines driver compliance and power dissipation in constant-current circuits |
| Viewing angle | ±60° - enables wide-angle illumination without secondary optics in indicator panels |
| Thermal resistance | 400 K/W - sets maximum allowable PCB copper area (≥16 mm²) for safe 50 mA operation |
| ESD rating | 2 kV HBM - mandates ESD-safe handling during assembly and board-level testing |
| AEC-Q101 qualified | Yes - validates suitability for automotive electronics including instrument clusters and exterior signage |
Pinout & Package
PLCC-2 surface-mount package with 2.8 mm × 2.2 mm footprint, 3.5 mm height, and molded white thermoplastic body. Anode and cathode terminals are identified by polarity marking on top surface and tape orientation (anode at cavity end).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to constant-current source; requires current-limiting resistor or driver IC |
| Cathode (K) | Negative LED terminal | Connected to ground or low-side switch; polarity reversal permitted only short-term per datasheet note |
Key Features
| Feature | Design Value |
|---|---|
| AlInGaP-on-Si die technology | Delivers high radiant efficiency and wavelength stability over temperature vs. traditional GaAsP |
| Luminous intensity ratio ≤1.6 | Ensures tight brightness uniformity (IVmax/IVmin) within each reel - critical for multi-LED arrays |
| JEDEC level 2a preconditioning | Guarantees moisture sensitivity compliance for Pb-free reflow without baking under standard factory conditions |
| Reflow/wave solder compatible | Supports industrial assembly using J-STD-020 profile (peak 260 °C) and CECC 00802 wave processes |
| White thermoplastic reflector | Maximizes light extraction and maintains color consistency across operating life and thermal cycles |

Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMO333U2AB-GS08 | Softer orange emission (600–611 nm dominant wavelength); identical luminous intensity range and package | Better suited for warm-tone UI elements where color differentiation from red alerts is required | Select when chromaticity must shift toward yellow-orange while retaining same drive and thermal specs |
| LA T67F-U2AB-24-1 (OSRAM) | Same dominant wavelength range and PLCC-2 footprint; different binning structure and tape packaging (non-GS08) | Requires validation of moisture sensitivity level and reflow profile compatibility per OSRAM spec | Use when cross-manufacturer sourcing is needed; verify JEDEC level 2a compliance and ESD rating match |
Compared with VLMK333U2AB-GS08, VLMO333U2AB-GS08 offers warmer chromaticity at identical drive and thermal performance, while LA T67F-U2AB-24-1 provides a second-source option with matched optical specs but distinct qualification documentation and packaging logistics.

FAQ
What is the maximum continuous forward current rating for VLMK333U2AB-GS08?
The VLMK333U2AB-GS08 is rated for 50 mA DC forward current when ambient temperature is ≤73 °C and mounted on a PCB with thermal pad area >16 mm². Exceeding this current or operating above the specified ambient limit risks exceeding the 125 °C maximum junction temperature and accelerated lumen depreciation. Always refer to Figure 1 (Maximum Permissible Forward Current vs. Ambient Temperature) in the official Vishay datasheet for derating guidance.
Is VLMK333U2AB-GS08 suitable for automotive applications?
Yes, VLMK333U2AB-GS08 is AEC-Q101 qualified, confirming its suitability for automotive electronics including dashboard indicators, exterior signage, and control panel status lights. It meets stress test requirements for temperature cycling, humidity, mechanical shock, and ESD - validated per JEDEC standards. The device operates from –40 °C to +100 °C and supports reflow soldering per J-STD-020, aligning with automotive manufacturing processes.
What does the "U2AB" suffix indicate in VLMK333U2AB-GS08?
In VLMK333U2AB-GS08, "U2AB" denotes the luminous intensity and dominant wavelength binning: "U" = intensity group (560–710 mcd), "2" = wavelength subgroup (614–622 nm), and "AB" = combined bin code specifying exact intensity/wavelength pairing per reel. This ensures consistent optical performance across production lots - no mixing of bins occurs within a single GS08 tape reel (1500 pcs).
Can VLMK333U2AB-GS08 be used in reverse-bias configuration?
The VLMK333U2AB-GS08 datasheet explicitly permits short-term reverse-bias operation (up to 5 V) as noted in Absolute Maximum Ratings and the general note. However, this is not intended for continuous use: reverse current is limited to 10 μA at VR = 5 V, and prolonged reverse conduction may degrade reliability. For bidirectional signaling, dedicated dual-LED or AC-driven solutions are recommended instead of relying on reverse conduction of VLMK333U2AB-GS08.
What is the viewing angle specification for VLMK333U2AB-GS08 and how is it measured?
VLMK333U2AB-GS08 has an angle of half intensity of ±60°, meaning luminous intensity drops to 50% of its peak value at 60° off-axis in both horizontal and vertical planes. This is measured at IF = 20 mA under standard test conditions (Tamb = 25 °C, 25 ms pulse), per CIE 127:2007 methodology. The symmetric PLCC-2 package geometry and internal reflector design produce this wide Lambertian-like distribution, eliminating need for external diffusers in many indicator applications.
