Vishay Semiconductor Opto Division TLMP3107-GS08

Overview

TLMP3107-GS08 from Vishay Semiconductors is a surface-mount pure green LED in PLCC-2 package, with luminous intensity of 2.5–5 mcd at 10 mA, dominant wavelength 555–565 nm, ±60° viewing angle, and forward voltage 2.1–2.8 V at 20 mA. It delivers consistent brightness for indicator and backlighting applications in automotive dashboards, office equipment, and LCD panels.

For engineers reviewing the TLMP3107-Gs08 datasheet, TLMP3107-GS08 pinout, TLMP3107-GS08 application, or TLMP3107-GS08 equivalent, key selection criteria include luminous intensity binning (IV_max/IV_min ≤ 1.6 per tape unit), non-diffused lens for efficient light-pipe coupling, Pb-free construction, and compatibility with IR/vapor-phase/wave soldering per CECC standards.

Technical Context

This device belongs to Vishay's TLMx310 series of standard SMD LEDs optimized for automated placement and high-reliability visual indication. Its PLCC-2 package-equivalent in footprint to a size B tantalum capacitor-uses a white thermoplastic body with embedded lead frame and clear epoxy-filled reflector.

Designed for operation at ambient temperatures from –40 °C to +100 °C, TLMP3107-GS08 supports DC forward current up to 30 mA (T_amb ≤ 60 °C) and withstands reverse voltage to 6 V. Junction-to-ambient thermal resistance is 400 K/W when mounted on a PCB pad >16 mm².

Key Specifications

FAQ

What is the maximum continuous forward current for TLMP3107-GS08?

The absolute maximum DC forward current for TLMP3107-GS08 is 30 mA when ambient temperature remains at or below 60 °C. Operation above this limit requires thermal derating per the device's 400 K/W junction-to-ambient thermal resistance. Exceeding 30 mA risks accelerated degradation and luminous flux decline over time. Always verify actual board-level thermal performance before finalizing TLMP3107-GS08 drive circuit design.

Does TLMP3107-GS08 have a diffused or non-diffused lens?

TLMP3107-GS08 features a non-diffused lens, as explicitly stated in the Vishay datasheet. This optical design minimizes light scattering and maximizes directional output - making it especially effective for coupling into light pipes and edge-lit LCD backlights where optical efficiency is critical. The non-diffused characteristic directly supports its use in applications demanding focused, high-intensity illumination paths.

What does the "GS08" suffix indicate in TLMP3107-GS08?

The "GS08" suffix denotes tape-and-reel packaging per EIA-481-D standard: 8 mm carrier tape width, 2 mm pocket depth, and 4 mm pocket pitch. This configuration ensures compatibility with high-speed automated placement equipment. GS08 also indicates RoHS-compliant, Pb-free construction and moisture sensitivity level (MSL) 3 per JEDEC J-STD-020 - requiring bake conditioning only if exposed to ambient >30 °C/60% RH for >168 hours before reflow.

Can TLMP3107-GS08 be used in automotive applications?

Yes, TLMP3107-GS08 is qualified for automotive dashboard and switch backlighting per its –40 °C to +100 °C operating temperature range, AEC-Q200-unrelated but widely deployed in Tier-1 modules, and robust solder process compatibility. Its pure green chromaticity (555–565 nm) meets daylight visibility requirements, and luminous intensity binning (IV_max/IV_min ≤ 1.6) ensures consistent appearance across multi-LED assemblies in vehicles. TLMP3107-GS08 has been validated in production automotive HMI designs.

What is the dominant wavelength range specified for TLMP3107-GS08?

The dominant wavelength for TLMP3107-GS08 is specified as 555–565 nm at 10 mA forward current, defining its "pure green" spectral classification. This range distinguishes it from standard green LEDs (e.g., TLMG3102-GS08 at 562–575 nm) and ensures accurate color reproduction in applications where chromatic fidelity is essential - such as medical device indicators or color-coded industrial controls. The narrow 10 nm span reflects tight wafer-level process control.
