Product details
Overview
VLMR33R2U2-GS18 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 280–450 mcd at 30 mA, and thermal resistance 400 K/W. It serves in high-reliability indicator and signage applications requiring stable color and intensity under industrial ambient conditions.
For engineers reviewing the VLMR33R2U2-GS18 datasheet, VLMR33R2U2-GS18 pinout, VLMR33R2U2-GS18 application, or VLMR33R2U2-GS18 equivalent, key selection criteria include its AEC-Q101 qualification, ±60° viewing angle, JESD22-A114-B ESD rating (2 kV), reflow compatibility per J-STD-020, and luminous intensity binning consistency (IVmax/IVmin ≤ 1.6).
Technical Context
This device uses AlInGaP-on-GaAs technology to deliver orange-red emission with peak wavelength ~624 nm and spectral bandwidth ≤18 nm at 50% relative intensity. Its PLCC-2 thermoplastic package features a white reflector cavity filled with clear epoxy, enabling efficient light extraction and consistent angular distribution.
Thermal management is defined by RthJA = 400 K/W when mounted on a PCB pad >16 mm², supporting continuous operation up to +100 °C ambient and junction temperature limits of +125 °C. It meets JEDEC level 2a preconditioning and withstands reverse voltage up to 5 V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar orange-red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR33T1U2-GS08 | Same die, identical optical/electrical specs, but supplied in 1500-piece GS08 tape (vs. 8000-piece GS18) | Lower per-reel quantity; suited for prototyping or low-volume production runs | Select when smaller batch sizes or faster sampling cycles are required |
| VLMS33S1U1-GS18 | Super red variant (626–638 nm), same PLCC-2 package, 50 mA rating, but higher luminous intensity (180–560 mcd) | Used where deeper red hue and higher intensity are preferred over orange-red chromaticity | Choose when color point must shift toward longer wavelengths while retaining mechanical and thermal compatibility |
Compared with VLMR33R2U2-GS18, VLMR33T1U2-GS08 offers identical performance in a smaller reel format, while VLMS33S1U1-GS18 provides a spectrally distinct super red alternative with higher intensity-both retain PLCC-2 footprint and AEC-Q101 qualification but differ in chromaticity and packaging scale.

FAQ
What is the maximum forward current rating for VLMR33R2U2-GS18?
The VLMR33R2U2-GS18 has a DC forward current rating of 50 mA at ambient temperatures ≤73 °C. This rating assumes mounting on a PCB pad >16 mm² to maintain thermal resistance at 400 K/W. Exceeding this current without adequate heatsinking risks accelerated lumen depreciation and junction temperature violation beyond +125 °C.
Is VLMR33R2U2-GS18 qualified for automotive applications?
Yes, VLMR33R2U2-GS18 is AEC-Q101 qualified, confirming its suitability for automotive interior and exterior lighting functions such as dashboard indicators, status lamps, and non-safety-critical signaling. It meets stress testing requirements for temperature cycling, humidity, and mechanical shock per the AEC standard.
What does the "U2" suffix indicate in VLMR33R2U2-GS18?
The "U2" suffix in VLMR33R2U2-GS18 denotes the luminous intensity bin: U-group (450–710 mcd) and subgroup 2 (560–710 mcd). This ensures consistent brightness within each reel-no mixing of intensity bins occurs, supporting predictable optical performance in production assemblies.
Can VLMR33R2U2-GS18 be used in reflow soldering processes?
Yes, VLMR33R2U2-GS18 is qualified for Pb-free reflow soldering per J-STD-020, with peak temperature up to 260 °C for ≤100 s. The device also supports vapor-phase and wave soldering per CECC 00802. Preconditioning per JEDEC level 2a is required prior to reflow to prevent moisture-related damage.
What is the viewing angle specification for VLMR33R2U2-GS18?
VLMR33R2U2-GS18 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 wide, symmetric viewing profile supports broad-area illumination and reduces directional sensitivity in panel-mounted indicator applications.
