Product details
Overview
VLMK233U1AA-GS08 from Vishay Semiconductors is an orange-red power MiniLED SMD device in a 2.3 mm × 1.3 mm × 1.4 mm package, delivering 450–1400 mcd luminous intensity at 20 mA, with dominant wavelength 611–622 nm and forward voltage 1.8–2.6 V. It serves as a high-reliability indicator light in automotive dashboards and industrial control panels under harsh ambient conditions.
For engineers reviewing the VLMK233U1AA-GS08 datasheet, VLMK233U1AA-GS08 pinout, VLMK233U1AA-GS08 application, or VLMK233U1AA-GS08 equivalent, this page delivers verified optical, electrical, thermal, and packaging data - including AEC-Q101 qualification, ±60° viewing angle, and JEDEC level 2a preconditioning - to support robust LED selection for safety-critical and high-temperature environments.
Technical Context
The VLMK233U1AA-GS08 is a surface-mount AlInGaP-on-Si LED optimized for stable photometric output across -40 °C to +100 °C operating temperature. Its 480 K/W junction-to-ambient thermal resistance requires ≥16 mm² copper pad area on PCB for rated 50 mA DC forward current handling.
It operates with 20 mA nominal drive current, supports IR reflow soldering per J-STD-020, and features ESD withstand up to 2 kV (JESD22-A114-B). The ±60° half-intensity angle and 18 nm spectral bandwidth enable uniform illumination in compact indicator layouts without secondary optics.
Key Specifications

IC Role / Device Role / Timing Role: Standalone visual status element driven by microcontroller GPIO pins via current-limiting resistors. Use Value: 2 kV ESD rating prevents assembly damage; luminous intensity binning (U1AA) ensures uniform panel appearance across thousands of units. | Use Scenario: Front-panel status and function indicators on consumer AV receivers, amplifiers, and media players where compact size and color fidelity are critical. IC Role / Device Role / Timing Role: Surface-mount discrete LED integrated into tight-layout front bezels with limited board space. Use Value: 2.3 × 1.3 mm footprint saves PCB real estate; soft orange-red hue enhances user interface aesthetics while maintaining readability. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR233T2V2-GS08 | Red (619–631 nm), lower min. luminous intensity (355 mcd), same package and VF range | Better suited for red-only signaling where chromaticity must meet strict red spectral boundaries | Select when red compliance (e.g., IEC 60838) is mandatory and orange-red is not permitted |
| VLMO233U1AA-GS08 | Soft orange (600–611 nm), identical luminous intensity range and VF, same AEC-Q101 qualification | Preferred for warm-orange aesthetic applications such as hospitality or premium audio UIs | Choose for broader orange spectrum where 605 nm typical λd improves perceived warmth vs. VLMK233U1AA-GS08's 616 nm |
Compared with VLMK233U1AA-GS08, VLMR233T2V2-GS08 shifts chromaticity toward red compliance at the cost of lower minimum intensity, while VLMO233U1AA-GS08 trades 5 nm shorter dominant wavelength for warmer tone - both retain identical thermal, mechanical, and reliability specs, enabling drop-in layout reuse where color tolerance permits.

FAQ
What is the maximum continuous forward current for VLMK233U1AA-GS08?
The VLMK233U1AA-GS08 supports a maximum DC forward current of 50 mA at ambient temperatures ≤60 °C. At higher temperatures, derating applies per Fig. 1 in the datasheet: e.g., 35 mA at 85 °C. Exceeding these limits risks accelerated lumen depreciation and junction overheating. Always verify thermal design using the 480 K/W RthJA value and ≥16 mm² copper pad area.
Is VLMK233U1AA-GS08 suitable for automotive applications?
Yes, VLMK233U1AA-GS08 is AEC-Q101 qualified and explicitly designed for automotive use, including dashboard illumination and exterior signaling. Its -40 to +100 °C operating range, 2 kV ESD rating, and JEDEC level 2a moisture sensitivity level meet stringent automotive manufacturing and field reliability requirements. The VLMK233U1AA-GS08 datasheet confirms qualification testing per AEC-Q101 Rev. D.
What does the "U1AA" suffix indicate in VLMK233U1AA-GS08?
The "U1AA" suffix in VLMK233U1AA-GS08 specifies its luminous intensity and dominant wavelength binning: "U" denotes 450–560 mcd intensity group, "1" indicates the first sub-bin within that group, and "AA" identifies the dominant wavelength bin centered at 616 nm (611–622 nm range). This ensures consistent brightness and color matching across reels shipped to the same customer.
Can VLMK233U1AA-GS08 be used in reverse-biased configuration?
No - the VLMK233U1AA-GS08 is not designed for reverse conduction. The datasheet explicitly states that reverse voltage operation is "suitable for short term application only", with absolute maximum VR = 5 V. Continuous reverse bias risks permanent degradation of the AlInGaP die. Always observe correct anode-cathode polarity during PCB layout and driver design for VLMK233U1AA-GS08.
What is the recommended soldering profile for VLMK233U1AA-GS08?
VLMK233U1AA-GS08 requires lead-free reflow per J-STD-020: peak temperature ≤260 °C for ≤10 s, time above 217 °C ≤60 s, ramp-up ≤3 °C/s, and ramp-down ≤6 °C/s. The device is preconditioned to JEDEC level 2a, so opened reels must be baked if exposed >672 hours at ≤30 °C/60 % RH. Refer to Fig. 10 in the VLMK233U1AA-GS08 datasheet for full profile details.
