Vishay Semiconductor Opto Division TLMP3100-GS08

Overview

TLMP3100-GS08 from Vishay Semiconductors is a surface-mount pure green LED in PLCC-2 package, delivering ≥1 mcd luminous intensity at 10 mA forward current, with dominant wavelength 555–565 nm and ±60° viewing angle-designed for backlighting LCD symbols and indicator panels in automotive dashboards and office equipment.

For engineers reviewing the TLMP3100-GS08 datasheet, TLMP3100-GS08 pinout, TLMP3100-GS08 application, or TLMP3100-GS08 equivalent, this device serves as a lead-free, low-profile SMD LED optimized for infrared/vapor-phase soldering, tight luminous intensity binning (IV_max/IV_min ≤ 1.6 per tape unit), and coupling to light pipes in space-constrained front-panel designs.

Technical Context

This pure green LED uses GaP-on-GaP semiconductor technology, emitting at peak wavelength 555 nm with forward voltage 2.1–2.8 V at 20 mA. Its PLCC-2 package features a white thermoplastic body with clear epoxy lens and internal reflector-enabling high optical efficiency and directional output.

Rated for DC forward current up to 30 mA at ≤60 °C ambient, it supports surge currents of 0.5 A (10 µs pulse) and operates across –40 to +100 °C. Thermal resistance junction-to-ambient is 400 K/W on a PCB pad >16 mm², limiting continuous power dissipation to 100 mW.

FAQ

What is the maximum continuous forward current rating for TLMP3100-GS08?

The TLMP3100-GS08 has an absolute maximum DC forward current of 30 mA when ambient temperature is ≤60 °C. Exceeding this limit risks accelerated lumen depreciation and junction overheating. For reliable operation at higher ambient temperatures, derating per Figure 2 in the datasheet is required-e.g., 20 mA at 85 °C ambient. Always verify thermal design with actual PCB copper area and airflow.

Does TLMP3100-GS08 support PWM dimming, and what is its junction capacitance?

Yes, TLMP3100-GS08 supports PWM dimming with a junction capacitance of 15 pF at 0 V and 1 MHz. This low capacitance enables clean switching up to at least 100 kHz without significant rise/fall time degradation. For optimal dimming linearity, use PWM frequencies above 1 kHz to avoid visible flicker while maintaining full brightness control range.

What is the dominant wavelength range of TLMP3100-GS08, and why does it matter for color-critical applications?

The TLMP3100-GS08 has a dominant wavelength range of 555–565 nm, defining its pure green chromaticity. This narrow band ensures consistent color rendering across production batches and distinguishes it from broader-spectrum green LEDs (e.g., TLMG3100 at 562–575 nm). In applications like medical device indicators or safety signage, this precise wavelength guarantees compliance with color-coded regulatory requirements.

Is TLMP3100-GS08 compatible with lead-free reflow soldering processes?

Yes, TLMP3100-GS08 is qualified for lead-free reflow soldering per JEDEC J-STD-020, including infrared and vapor-phase processes. Its package withstands peak temperatures up to 260 °C for ≤5 seconds. The device is also RoHS-compliant and lead (Pb)-free, meeting EU Directive 2011/65/EU requirements without compromising solder joint integrity or optical performance.

How is luminous intensity binned for TLMP3100-GS08, and what does IVmax/IVmin ≤ 1.6 mean in practice?

TLMP3100-GS08 is binned so that the ratio of maximum to minimum luminous intensity (IV_max/IV_min) within a single 8 mm tape unit is ≤1.6. In practice, this means adjacent LEDs on the same reel will exhibit no more than a 60% brightness difference at 10 mA-eliminating visible mismatch in multi-LED arrays and reducing need for manual sorting during assembly of uniform indicator panels.
