Product details
Overview
VLMS33S1T2-GS08 from Vishay Semiconductors is a surface-mount super red power LED in PLCC-2 package, designed for 30 mA DC operation with 290 mcd typical luminous intensity, 630 nm dominant wavelength, and ±60° viewing angle. It delivers high brightness for indicator and backlighting applications in automotive dashboards and traffic signage.
For engineers reviewing the VLMS33S1T2-GS08 datasheet, VLMS33S1T2-GS08 pinout, VLMS33S1T2-GS08 application, or VLMS33S1T2-GS08 equivalent, key selection criteria include forward voltage tolerance (1.7–2.5 V), thermal resistance (400 K/W), AEC-Q101 qualification, and AlInGaP-on-GaAs chip technology for stable red emission under industrial temperature cycling.
Technical Context
The VLMS33S1T2-GS08 uses AlInGaP-on-GaAs semiconductor technology to achieve narrow spectral output centered at 630 nm (dominant) with 17 nm bandwidth, enabling high color purity in signaling applications. Its PLCC-2 thermoplastic package integrates a white reflector cavity filled with clear epoxy, optimizing light extraction and angular uniformity.
Rated for 50 mA maximum DC forward current at ambient ≤73 °C and junction temperature up to +125 °C, it supports reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802. Preconditioned to JEDEC level 2a and qualified to AEC-Q101, it meets automotive-grade reliability requirements for dashboard and exterior lighting.

Equivalent & Alternatives
The following parts are listed as comparable options for similar visible-light indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMS33S1U1-GS08 | Same package and technology; higher luminous intensity bin (U: 450–560 mcd vs. T: 280–450 mcd) | Better suited for outdoor signage requiring higher brightness; may require driver adjustment to avoid oversaturation in enclosed panels | Select VLMS33S1U1-GS08 when >450 mcd minimum intensity is required and optical diffusion is limited |
| LST67B-S1T2 | OSRAM equivalent; identical optical specs (630 nm, ±60°, 290 mcd), same PLCC-2 footprint, but different thermal pad layout and JEDEC MSL rating | Compatible in function and form, but requires validation of solder profile due to differing moisture sensitivity classification | Choose LST67B-S1T2 only after confirming reflow compatibility with existing line setup and verifying thermal pad thermal performance |
Compared with VLMS33S1T2-GS08, VLMS33S1U1-GS08 offers higher intensity within the same super red binning group, while LST67B-S1T2 provides cross-manufacturer sourcing flexibility at the cost of requalification effort for thermal and moisture handling.

FAQ
What is the maximum continuous forward current rating for VLMS33S1T2-GS08?
The VLMS33S1T2-GS08 is rated for 50 mA DC forward current when ambient temperature is ≤73 °C and mounted on a PCB with ≥16 mm² copper pad. At higher ambient temperatures, derating is required per Figure 1 in the datasheet; at 100 °C ambient, maximum allowable current drops to approximately 25 mA to maintain junction temperature ≤125 °C.
Does VLMS33S1T2-GS08 require baking before reflow soldering?
Yes - VLMS33S1T2-GS08 is moisture-sensitive per JESD22-A112 level 2a. If the sealed aluminum bag has been opened and the device is exposed to >60 % RH at 30 °C for more than 672 hours, baking at 60 °C ±5 °C for 96 hours under <5 % RH is required prior to reflow. The dry pack label on the reel indicates exposure time and MSL status.
Is VLMS33S1T2-GS08 compatible with lead-free reflow processes?
Yes - VLMS33S1T2-GS08 is qualified for Pb-free reflow per J-STD-020. Its recommended profile peaks at 245 °C (max 260 °C for ≤10 s), with ramp rates ≤3 °C/s (up) and ≤6 °C/s (down). Figure 26 in the datasheet provides the full profile, and the device withstands up to two reflow cycles without degradation.
What does the "T2" suffix in VLMS33S1T2-GS08 indicate?
The "T2" suffix denotes the luminous intensity bin within the super red VLM.33.. family: Group T (280–450 mcd) and subgroup 2 (tighter distribution within that group). This binning ensures consistent brightness across reels - no mixing of intensity groups occurs per tape, supporting predictable optical system calibration.
Can VLMS33S1T2-GS08 be used in reverse-biased configuration?
No - although the datasheet notes reverse conduction is "suitable for short-term application," VLMS33S1T2-GS08 is not designed for sustained reverse operation. Its absolute maximum reverse voltage is only 5 V; exceeding this risks permanent junction damage. Always observe polarity during PCB layout and driver design.
