Product details
Overview
VLMS33S1U1-GS08 from Vishay Semiconductors is a surface-mount super red power LED in PLCC-2 package, designed for 30 mA DC operation with 180–290 mcd typical luminous intensity, 626–638 nm dominant wavelength, and ±60° viewing angle. It delivers high-brightness indicator lighting in automotive dashboards and traffic signage under industrial ambient conditions.
For engineers reviewing the VLMS33S1U1-GS08 datasheet, VLMS33S1U1-GS08 pinout, VLMS33S1U1-GS08 application, or VLMS33S1U1-GS08 equivalent, key selection criteria include luminous intensity binning (U1 group), thermal resistance (400 K/W), AEC-Q101 qualification, and compatibility with reflow soldering per J-STD-020.
Technical Context
This AlInGaP-on-GaAs LED operates at 30 mA forward current with 1.7–2.5 V forward voltage range and exhibits stable spectral output: dominant wavelength centered at 630 nm, peak wavelength at 641 nm, and narrow 17 nm spectral bandwidth. Its ±60° half-intensity angle enables wide-angle illumination without secondary optics.
The device features 400 K/W junction-to-ambient thermal resistance when mounted on ≥16 mm² PCB copper pad, supports 50 mA absolute maximum pulsed drive, and maintains luminous intensity ratio IVmax/IVmin ≤ 1.6 within each reel-ensuring consistent brightness across production batches.

IC Role / Device Role / Timing Role: Low-power, eye-catching status emitter with consistent color point across production lots. Use Value: Luminous intensity ratio ≤1.6 per reel eliminates manual sorting; 8 mm tape format enables high-speed pick-and-place placement. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMS33S1T2-GS08 | Lower luminous intensity bin (T2: 180–450 mcd vs. U1: 180–560 mcd); identical optical/electrical specs otherwise | Suitable where lower brightness suffices and tighter cost control is required | Select when design tolerates reduced max intensity and needs lower BOM cost |
| LST67B-T1U1 | OSRAM equivalent; same PLCC-2 footprint, 625–635 nm dominant wavelength, 190–550 mcd at 30 mA | Drop-in alternative with identical mechanical and photometric performance | Choose for dual-sourcing flexibility while maintaining identical optical output and PCB layout |
Compared with VLMS33S1U1-GS08, VLMS33S1T2-GS08 offers lower max intensity at reduced cost, while LST67B-T1U1 provides second-source assurance with identical photometric and thermal behavior-both preserve the ±60° viewing angle and AEC-Q101 compliance needed for automotive and industrial use.

FAQ
What is the maximum continuous forward current for VLMS33S1U1-GS08?
The VLMS33S1U1-GS08 supports a maximum DC forward current of 50 mA at ambient temperatures ≤73 °C when mounted on a PCB with thermal resistance ≤400 K/W. At 30 mA-its rated operating point-it delivers 180–290 mcd luminous intensity with stable forward voltage of 1.7–2.5 V. Exceeding 50 mA risks accelerated degradation and thermal runaway.
How does the U1 luminous intensity bin affect system-level design?
The U1 bin for VLMS33S1U1-GS08 specifies a luminous intensity range of 450–560 mcd at 30 mA, ensuring tight brightness matching across all units on a single reel. This eliminates need for post-assembly sorting in multi-LED arrays such as traffic signal modules or automotive dashboards, reducing manufacturing cost and improving visual uniformity.
Is VLMS33S1U1-GS08 compatible with lead-free reflow soldering processes?
Yes, VLMS33S1U1-GS08 is fully compatible with Pb-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. Its PLCC-2 package and internal construction have been validated for thermal shock resistance during standard IR reflow profiles, including ramp rates up to 3 °C/s and cooling rates up to 6 °C/s.
What does AEC-Q101 qualification mean for VLMS33S1U1-GS08 in automotive applications?
AEC-Q101 qualification confirms that VLMS33S1U1-GS08 has passed accelerated stress tests-including temperature cycling, humidity bias, and ESD-required for discrete semiconductors in automotive environments. This validates its use in non-safety-critical but reliability-demanding locations like dashboard indicators and door module status lights.
Can VLMS33S1U1-GS08 be used in reverse-biased configurations?
The datasheet notes that short-term reverse bias is permissible for VLMS33S1U1-GS08, with absolute maximum reverse voltage rated at 5 V. However, sustained reverse operation is not recommended, as it may cause irreversible damage to the AlInGaP chip. For bidirectional signaling, external protection circuitry is required.
