Product details
Overview
VLMF31Q2T1-GS08 from Vishay Semiconductors is a high-intensity surface-mount soft orange LED in PLCC-2 package, built on AlInGaP-on-GaAs technology, with dominant wavelength 598–611 nm, luminous intensity 90–355 mcd at 20 mA, and forward voltage 2.0–2.6 V - optimized for automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLMF31Q2T1-GS08 datasheet, VLMF31Q2T1-GS08 pinout, VLMF31Q2T1-GS08 application, or VLMF31Q2T1-GS08 equivalent, this page delivers verified optical/electrical specs, AEC-Q101 qualification status, JEDEC level 2a preconditioning compliance, and tape-and-reel packaging details (GS08 = 1500 pcs/reel) critical for SMT production planning and automotive-grade design validation.
Technical Context
This device operates as a DC-driven visible-light emitter with ±60° viewing angle and non-diffused lens - enabling precise light coupling into light pipes and LCD edge guides. Its thermal resistance junction-to-ambient is 400 K/W when mounted on ≥16 mm² PCB pad, supporting continuous operation up to +100°C ambient.
The VLMF31Q2T1-GS08 is rated for 30 mA DC forward current and 5 V reverse voltage, with surge capability of 100 mA for ≤10 μs pulses. Junction capacitance is 15 pF at 0 V and 1 MHz, confirming suitability for moderate-speed multiplexed indicator circuits without signal integrity concerns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar visible-light SMD LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSRAM LOT676-Q2T1 | Identical soft orange binning, same PLCC-2 package, but rated for 25 mA max forward current vs. 30 mA for VLMF31Q2T1-GS08 | Lower max current reduces thermal margin in high-temperature enclosures; identical optical performance in backlighting | Select LOT676-Q2T1 only if legacy OSRAM supply chain alignment is required; otherwise prefer VLMF31Q2T1-GS08 for higher current headroom |
| Vishay VLMF31Q2T1 | No GS08 tape code - shipped in GS18 (8000 pcs/reel); identical electrical/optical specs and AEC-Q101 qualification | Same functional performance; GS18 offers better cost-per-unit for high-volume production runs | Choose VLMF31Q2T1-GS08 for prototyping and low-volume builds requiring 1500-piece reels; use VLMF31Q2T1 (GS18) for mass production |
Compared with OSRAM LOT676-Q2T1, the VLMF31Q2T1-GS08 offers +20% higher DC forward current rating and identical optical binning - improving thermal design margin in automotive applications. Against the untaped VLMF31Q2T1, the GS08 variant provides smaller reel size and faster setup for low-volume SMT lines.

FAQ
What is the maximum continuous forward current rating for the VLMF31Q2T1-GS08?
The VLMF31Q2T1-GS08 has a maximum DC forward current rating of 30 mA at ambient temperatures ≤85°C. This value is defined in the Absolute Maximum Ratings table and must not be exceeded to maintain reliability and AEC-Q101 qualification integrity. Derating is required above 85°C ambient, with full derating to zero at +125°C junction temperature. The VLMF31Q2T1-GS08 datasheet specifies thermal resistance junction-to-ambient as 400 K/W on ≥16 mm² copper pads.
Is the VLMF31Q2T1-GS08 suitable for automotive applications?
Yes, the VLMF31Q2T1-GS08 is AEC-Q101 qualified and explicitly designed for automotive use cases including dashboard backlighting and switch indicators. It meets temperature cycling, humidity bias, and mechanical shock requirements defined in the AEC-Q101 stress test standard. Its operating temperature range of –40°C to +100°C ambient and junction temperature limit of +125°C further validate its suitability for under-hood and cabin-mounted electronics.
What does the "GS08" suffix indicate in VLMF31Q2T1-GS08?
The "GS08" suffix denotes Vishay's standard 8 mm antistatic blister tape packaging option containing 1500 pieces per reel. This format complies with EIA-481-D and is optimized for high-speed pick-and-place equipment. The GS08 tape features embossed cavities, top cover tape, and moisture barrier bagging with JESD22-A112 level 2a labeling - ensuring safe handling and reflow readiness for SMT production lines.
How is luminous intensity binned for the VLMF31Q2T1-GS08?
The VLMF31Q2T1-GS08 is binned into luminous intensity groups P through T, with group Q specifying 71–112 mcd (Q1) or 90–112 mcd (Q2) at 20 mA. The "Q2" in the part number confirms shipment from the higher-intensity Q2 sub-bin. Each reel contains only one intensity group - no mixing - ensuring consistent brightness across all units on a given reel, which simplifies design and eliminates post-assembly brightness sorting.
Does the VLMF31Q2T1-GS08 require special handling for moisture sensitivity?
Yes, the VLMF31Q2T1-GS08 is classified as MSL level 2a per JEDEC J-STD-020, meaning it may be exposed to factory floor conditions for up to 672 hours at ≤30°C/60% RH before reflow. Once the moisture barrier bag is opened, dry box storage (<10% RH) is recommended. If exposure limits are exceeded, baking per J-STD-033 is required - e.g., 96 hours at 60°C +5°C/<5% RH - before reflow to prevent popcorning failure. The VLMF31Q2T1-GS08 reel label includes the EIA JEDEC level 2a indicator.
