Product details
Overview
VLMK31R1S2-GS08 from Vishay Semiconductors is a red surface-mount LED based on AlInGaP-on-GaAs technology, housed in a PLCC-2 package with ±60° viewing angle, 112–280 mcd luminous intensity at 20 mA, 630 nm dominant wavelength, and 1.9–2.6 V forward voltage - optimized for automotive dashboard backlighting and indicator applications.
For engineers reviewing the VLMK31R1S2-GS08 datasheet, VLMK31R1S2-GS08 pinout, VLMK31R1S2-GS08 application, or VLMK31R1S2-GS08 equivalent, this page delivers verified optical/electrical specs, AEC-Q101 qualification status, JEDEC level 2a preconditioning compliance, ESD robustness (2 kV), and tape-and-reel packaging details (GS08 = 1500 pcs/reel).
Technical Context
The VLMK31R1S2-GS08 is a non-diffused, low-profile SMD LED with clear epoxy lens and white thermoplastic reflector, enabling efficient light coupling into light pipes and LCD backlights. Its PLCC-2 package features a lead frame embedded in thermoplastic, supporting IR reflow, vapor-phase, and wave soldering per J-STD-020 and CECC 00802.
Optically, it delivers dominant wavelength of 630 nm and peak wavelength of 643 nm, with angular intensity distribution centered at 0° and half-intensity at ±60°. Electrically, it operates up to 30 mA DC forward current, withstands 5 V reverse voltage, and exhibits 15 pF junction capacitance at 0 V/1 MHz - suitable for high-reliability indicator and backlight circuits in harsh ambient conditions (-40 to +100 °C).
