Product details
Overview
VLMS333T2V2-GS08 from Vishay Semiconductors is a surface-mount super red power LED in PLCC-2 package, rated for 50 mA DC forward current, delivering 355–1120 mcd luminous intensity at 20 mA, with dominant wavelength 626–639 nm and ±60° viewing angle - used in traffic signal indicators and dashboard illumination.
For engineers reviewing the VLMS333T2V2-GS08 datasheet, VLMS333T2V2-GS08 pinout, VLMS333T2V2-GS08 application, or VLMS333T2V2-GS08 equivalent, this page provides verified optical/electrical specs, thermal resistance (400 K/W), AEC-Q101 qualification, AlInGaP-on-Si technology, and PLCC-2 mechanical layout for automotive-grade indicator design.
Technical Context
The VLMS333T2V2-GS08 uses AlInGaP-on-Si die technology to achieve high radiant efficiency and stable chromaticity across temperature. Its PLCC-2 thermoplastic package features an internal white reflector filled with clear epoxy, enabling uniform light extraction and ±60° half-intensity beam pattern.
Rated for 50 mA continuous drive at ambient ≤73 °C, it maintains junction temperature ≤125 °C with 400 K/W thermal resistance when mounted on ≥16 mm² PCB copper pad. It complies with JEDEC level 2a preconditioning and supports reflow, vapor-phase, and wave soldering per CECC 00802 and J-STD-020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLMR333U1AA-GS08 | Red (619–631 nm), higher typical luminous intensity (750 mcd vs. 550 mcd), same PLCC-2 package and 50 mA rating | Used where broader red spectrum is acceptable (e.g., non-traffic signage); not compliant with super red chromaticity bins | Select when color tolerance permits λd >625 nm and higher brightness is prioritized over strict super red definition |
| LS T67F-T2V2-1-1 | OSRAM cross-reference; identical optical binning (T2V2), same PLCC-2 footprint and thermal spec, but different packaging labeling and traceability | Direct functional replacement in legacy designs using OSRAM-sourced boards; may require updated documentation for audit trails | Choose for supply chain diversification while maintaining identical photometric and mechanical behavior |
Compared with VLMS333T2V2-GS08, VLMR333U1AA-GS08 offers higher intensity but shifts toward standard red chromaticity, whereas LS T67F-T2V2-1-1 delivers identical photometric performance with alternate logistics tracking - both require no PCB redesign but differ in compliance scope and sourcing origin.

FAQ
What is the maximum continuous forward current rating for VLMS333T2V2-GS08?
The VLMS333T2V2-GS08 is rated for 50 mA DC forward current when ambient temperature does not exceed 73 °C. This rating assumes proper thermal management - specifically mounting on a PCB pad area greater than 16 mm² to maintain junction temperature ≤125 °C. Exceeding 50 mA or operating above 73 °C ambient requires derating per the datasheet's IF vs. Tamb curve.
Is VLMS333T2V2-GS08 suitable for automotive applications?
Yes, VLMS333T2V2-GS08 is AEC-Q101 qualified, confirming its suitability for automotive applications including dashboard illumination, warning indicators, and exterior status lights. It operates across -40 to +100 °C ambient temperature and meets JEDEC level 2a preconditioning, making it appropriate for under-hood and cabin-mounted systems where reliability and thermal stability are essential.
What does the "T2V2" suffix indicate in VLMS333T2V2-GS08?
In VLMS333T2V2-GS08, "T2V2" denotes the luminous intensity and dominant wavelength bin: "T" specifies the intensity group (355–450 mcd), and "V2" indicates the wavelength group (626–639 nm super red). This binning ensures consistent photometric performance across reels - each tape contains only one intensity/wavelength combination, avoiding mixed-bins that could cause visual mismatch in multi-LED assemblies.
Can VLMS333T2V2-GS08 be soldered using lead-free reflow processes?
Yes, VLMS333T2V2-GS08 is compatible with lead-free reflow soldering per J-STD-020, supporting peak temperatures up to 260 °C for ≤10 seconds. The device has undergone JEDEC level 2a preconditioning and is supplied in dry-packed antistatic tape (GS08 = 1500 pcs/reel), eliminating moisture sensitivity concerns when handled per EIA/JEDEC guidelines before reflow.
What is the thermal resistance junction-to-ambient for VLMS333T2V2-GS08?
The thermal resistance junction-to-ambient (RthJA) for VLMS333T2V2-GS08 is 400 K/W when mounted on a PCB with a minimum copper pad area of 16 mm². This value is measured under standardized test conditions and directly impacts maximum allowable drive current at elevated ambient temperatures - for example, at 73 °C ambient, the 50 mA rating is maintained; beyond that, current must be reduced to prevent exceeding 125 °C junction temperature.
