Product details
Overview
VLMS31J1L2-GS08 from Vishay Semiconductors is a high-intensity red surface-mount LED in PLCC-2 package, emitting at 630 nm dominant wavelength with 9 mcd typical luminous intensity at 10 mA, 1.9–2.6 V forward voltage at 20 mA, and ±60° viewing angle-designed for indicator and backlighting in telecommunication and office equipment.
For engineers reviewing the VLMS31J1L2-GS08 datasheet, VLMS31J1L2-GS08 pinout, VLMS31J1L2-GS08 application, or VLMS31J1L2-GS08 equivalent, key selection criteria include luminous intensity binning (L2 group), GaAsP-on-GaP chip technology, JEDEC level 2a preconditioning compliance, 2 kV ESD withstand rating, and compatibility with IR reflow soldering per J-STD-020.
Technical Context
This red SMD LED uses GaAsP-on-GaP semiconductor technology to deliver stable visible-light emission with dominant wavelength tightly binned between 624 nm and 638 nm. Its non-diffused lens enables efficient coupling to light pipes and LCD backlights, while the PLCC-2 thermoplastic package provides mechanical robustness and thermal resistance of 400 K/W junction-to-ambient when mounted on ≥16 mm² PCB pad.
The device operates across –40 °C to +100 °C ambient temperature range with 20 mA DC forward current rating and 6 V reverse voltage limit. Luminous intensity ratio within one tape reel is controlled to ≤1.6 (IVmax/IVmin), ensuring consistent brightness for automated assembly and visual uniformity in multi-LED arrays.
Key Specifications

FAQ
What is the luminous intensity range of the VLMS31J1L2-GS08?
The VLMS31J1L2-GS08 has a luminous intensity range of 4.5–18 mcd at 10 mA forward current, corresponding to the L2 bin classification per Vishay's intensity grouping table. This range ensures consistent brightness across reels shipped from the same production lot, with no mixing of intensity groups on a single tape.
Does the VLMS31J1L2-GS08 require baking before reflow soldering?
The VLMS31J1L2-GS08 is preconditioned to JEDEC level 2a and shipped in moisture-barrier packaging. Baking is not required if mounted within 672 hours of opening the dry bag under factory conditions (<30 °C / 60 % RH). If exposure exceeds this, baking at 60 °C for 96 h at <5 % RH is specified per JESD22-A112.
What is the dominant wavelength specification for VLMS31J1L2-GS08?
The dominant wavelength of VLMS31J1L2-GS08 is specified as 624–638 nm at 10 mA forward current, with a typical value of 630 nm. This narrow band supports consistent red color reproduction in multi-LED arrays and meets common visual signaling standards for status indicators.
Can VLMS31J1L2-GS08 be driven directly from a 3.3 V microcontroller GPIO?
Yes, VLMS31J1L2-GS08 can be driven directly from a 3.3 V GPIO when paired with an appropriate current-limiting resistor. At 20 mA forward current, its VF ranges from 1.9 V to 2.6 V, leaving sufficient headroom for resistor-based current control without exceeding GPIO drive capability or thermal limits.
What is the thermal resistance junction-to-ambient for VLMS31J1L2-GS08?
The thermal resistance junction-to-ambient (RthJA) of VLMS31J1L2-GS08 is 400 K/W when mounted on a PCB with copper pad area greater than 16 mm². This value enables continuous 20 mA operation up to 74 °C ambient temperature without derating, supporting use in enclosed industrial enclosures.
