Vishay Semiconductor Opto Division TLMG3100-GS08

Overview

TLMG3100-GS08 from Vishay Semiconductors is a surface-mount green LED in PLCC-2 package, with luminous intensity ≥4 mcd at 10 mA, dominant wavelength 562–575 nm, and ±60° viewing angle-designed for indicator and backlighting applications in automotive dashboards and office equipment.

For engineers reviewing the TLMG3100-GS08 datasheet, TLMG3100-GS08 pinout, TLMG3100-GS08 application, or TLMG3100-GS08 equivalent, key selection criteria include forward voltage (2.2–2.8 V @ 20 mA), DC forward current rating (30 mA), thermal resistance (400 K/W), and luminous intensity binning (IV_max/IV_min ≤ 1.6 per tape unit).

Technical Context

This green LED uses GaP-on-GaP chip technology and features a non-diffused lens optimized for coupling to light pipes and flat backlighting. Its PLCC-2 package conforms to EIA/ICE standards and supports infrared, vapor-phase, and wave soldering per CECC specifications.

The device operates across –40 °C to +100 °C ambient temperature, with maximum junction temperature of 100 °C and reverse voltage rating of 6 V. Luminous intensity is binned at IF = 10 mA, and relative intensity vs. temperature curves confirm stable output up to 80 °C.

FAQ

What is the maximum DC forward current rating for the TLMG3100-GS08?

The TLMG3100-GS08 has a maximum DC forward current of 30 mA when ambient temperature is ≤60 °C. Exceeding this value without thermal derating risks accelerated lumen depreciation and reduced lifetime. The device's thermal resistance (400 K/W) requires adequate PCB copper area (≥16 mm²) to maintain junction temperature below 100 °C under continuous operation. Always verify actual board-level thermal performance for your TLMG3100-GS08 layout.

What does the "GS08" suffix indicate in TLMG3100-GS08?

The "GS08" suffix denotes tape-and-reel packaging in 8 mm carrier tape, conforming to EIA-481 standard, with component orientation and pocket pitch optimized for automated placement equipment. This packaging format ensures consistent feeding and placement accuracy for high-volume manufacturing. The TLMG3100-GS08 is not supplied in bulk or ammo-pack formats-only GS08 reel configuration is orderable per Vishay's documentation.

Is the TLMG3100-GS08 compatible with lead-free reflow soldering processes?

Yes, the TLMG3100-GS08 is qualified for lead-free reflow soldering with a peak temperature of 260 °C for ≤5 seconds, meeting JEDEC J-STD-020 requirements. Its Pb-free construction (e3 marking) and thermoplastic package withstand standard SAC305 alloy profiles. No special preheat or cooling ramp rates are mandated beyond standard SMD LED guidelines-verify compatibility with your specific reflow oven profile using TLMG3100-GS08 thermal characteristics.

How is luminous intensity binned for the TLMG3100-GS08?

The TLMG3100-GS08 is binned for luminous intensity such that IV_max/IV_min ≤ 1.6 within each 8 mm tape unit, measured at IF = 10 mA and Tamb = 25 °C. This ensures minimal brightness variation across LEDs placed from the same reel-critical for uniform panel lighting. Binning is performed at wafer level and verified during final test; no additional sorting is needed for consistent appearance in multi-LED arrays using TLMG3100-GS08.

What is the dominant wavelength range of the TLMG3100-GS08?

The TLMG3100-GS08 has a dominant wavelength range of 562–575 nm, placing its output in the standard green region of the visible spectrum. This range is defined per CIE 1931 chromaticity coordinates and confirmed under standardized test conditions (IF = 10 mA, Tamb = 25 °C). It differs from "pure green" variants like TLMP3101-GS08 (555–565 nm), making TLMG3100-GS08 suitable for general-purpose green indication where spectral precision is secondary to luminance.
