Overview
VLMS235S2U1-GS08 from Vishay Semiconductors is a super red power MiniLED SMD device in a 2.3 mm × 1.3 mm × 1.4 mm package, delivering 224–560 mcd luminous intensity at 20 mA, with dominant wavelength 626–639 nm and forward voltage 1.8–2.6 V. It is AEC-Q101 qualified and designed for high-reliability automotive dashboard illumination and industrial indicator lighting.
For engineers reviewing the VLMS235S2U1-GS08 datasheet, VLMS235S2U1-GS08 pinout, VLMS235S2U1-GS08 application, or VLMS235S2U1-GS08 equivalent, this page provides verified optical, electrical, thermal, and packaging data - including luminous intensity binning (Group S), ±60° viewing angle, 2 kV ESD rating, JEDEC level 2a preconditioning, and IR reflow compatibility - to support LED selection, layout, and reliability validation.
Technical Context
The VLMS235S2U1-GS08 uses AlInGaP-on-Si technology to achieve high radiant efficiency in a miniature surface-mount package. Its optical design delivers a symmetric ±60° half-intensity viewing angle and narrow spectral bandwidth (Δλ = 18 nm), enabling precise color targeting in indicator applications.
Thermally, it features a junction-to-ambient thermal resistance of 480 K/W when mounted on a PCB with pad area >16 mm², supporting continuous DC operation up to 50 mA at Tamb ≤ 60 °C. It is rated for -40 °C to +100 °C operating temperature and qualified per AEC-Q101 for automotive use.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 224–560 mcd at 20 mA - defines brightness range for visibility under ambient light in indicator applications |
| Dominant wavelength | 626–639 nm - specifies super red chromaticity compliant with automotive color coding standards |
| Forward voltage | 1.8–2.6 V at 20 mA - determines minimum driver headroom and power dissipation (max 130 mW) |

| Ambient temp. range | -40 to +100 °C - supports under-hood and industrial control cabinet deployment |
Pinout & Package
VLMS235S2U1-GS08 is housed in a 2.3 mm × 1.3 mm × 1.4 mm MiniLED SMD package with cathode marked by an anode indicator (dot). The device uses standard reverse-polarity SMD LED footprint per drawing No. 6.541-5090.01-4 (Issue 4).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current-limiting resistor or constant-current driver output; polarity must be observed to avoid reverse-bias damage |
| Cathode (K) | Negative terminal | Connected to ground or low-side switch; marked by dot on package top surface per datasheet diagram |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, humidity bias, and mechanical shock |
| JEDEC level 2a preconditioning | Enables safe IR reflow soldering without popcorning; requires dry pack storage after bag opening |
| Luminous intensity binning (Group S) | Ensures consistent brightness across reels: 224–280 mcd at 20 mA for predictable visual uniformity |
| AlInGaP-on-Si die technology | Delivers high radiant efficiency and stable wavelength over temperature vs. traditional GaAsP |
| 2 kV HBM ESD rating | Reduces need for external protection circuitry in low-voltage control interfaces |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR235T2V1-GS08 | Higher luminous intensity (355–900 mcd), red (619–631 nm) vs. super red; same package and VF range | Better suited for general-purpose red indication where chromaticity tolerance is wider | Select when higher brightness or broader red spectrum is acceptable; not suitable for applications requiring strict 626+ nm super red compliance |
| OSRAM LS M67F-S2U2-1 | Direct cross-reference per Vishay's Crossing Table; identical luminous intensity bin (S2U1/S2U2), same package and optical specs | Same automotive and industrial use cases; validated alternative for supply chain diversification | Drop-in replacement with matching photometric and thermal behavior; verify reel labeling and moisture sensitivity handling per JESD22-A112 level 2a |
Compared with VLMS235S2U1-GS08, VLMR235T2V1-GS08 offers higher brightness but narrower spectral compliance for super red, while OSRAM LS M67F-S2U2-1 matches its photometric binning and mechanical form factor - making it the preferred alternative for continuity-critical automotive designs.

FAQ
What is the maximum continuous forward current for VLMS235S2U1-GS08?
The VLMS235S2U1-GS08 supports a maximum DC forward current of 50 mA when ambient temperature is ≤60 °C and thermal resistance is maintained at 480 K/W via proper PCB pad design (>16 mm² copper area). At higher temperatures, derating is required per Fig. 1 in the datasheet. Exceeding this limit risks accelerated lumen depreciation and junction overheating.
Is VLMS235S2U1-GS08 suitable for automotive applications?
Yes, VLMS235S2U1-GS08 is AEC-Q101 qualified and explicitly designed for automotive use, including dashboard illumination and exterior signaling. Its -40 °C to +100 °C operating range, 125 °C junction temperature rating, and JEDEC level 2a preconditioning confirm suitability for under-hood and cabin environments subject to thermal cycling and vibration.
What does the "S2U1" suffix in VLMS235S2U1-GS08 indicate?
The "S2U1" suffix denotes the luminous intensity and dominant wavelength binning: "S" = intensity group 224–280 mcd, "2" = second sub-bin within S group, and "U1" = dominant wavelength bin 626–630 nm. This ensures consistent optical performance across production reels - critical for color-matching in multi-LED assemblies.
How should VLMS235S2U1-GS08 be handled after opening the moisture barrier bag?
After opening the sealed aluminum bag, VLMS235S2U1-GS08 must be mounted within 672 hours at ≤30 °C / 60 % RH or stored in a dry box (<10 % RH). If exposed beyond this limit, baking per JESD22-A112 is required: 96 h at 60 °C +5 °C / <5 % RH for reels. Failure to comply risks popcorning during reflow.
Does VLMS235S2U1-GS08 support reverse-bias operation?
No - VLMS235S2U1-GS08 is not designed for reverse operation. The datasheet explicitly states "Not designed for reverse operation" under Absolute Maximum Ratings, and reverse voltage (VR) is unspecified. Applying reverse bias, even briefly, may cause irreversible degradation or catastrophic failure.
