Product details
Overview
TLMB3100-GS08 from Vishay is a blue surface-mount LED using GaN-on-SiC technology in a PLCC-2 package, delivering ≥4.0 mcd luminous intensity at 10 mA, 466 nm dominant wavelength, and ±60° viewing angle-designed for dashboard backlighting and indicator applications in automotive and office equipment.
For engineers reviewing the TLMB3100-GS08 datasheet, TLMB3100-GS08 pinout, TLMB3100-GS08 application, or TLMB3100-GS08 equivalent, key selection criteria include forward voltage (3.9–4.5 V), thermal resistance (400 K/W), ESD Class 1 rating, non-diffused lens for light-pipe coupling, and compatibility with IR/vapor-phase/wave soldering per CECC standards.
Technical Context
This device operates as a discrete visible-light emitter with fixed spectral output defined by GaN-on-SiC semiconductor physics. Its optical behavior is characterized by a narrow dominant wavelength (466 nm) and peak wavelength (428 nm), indicating strong blue emission with minimal green/red spectral leakage.
The PLCC-2 package integrates a white thermoplastic body over a lead frame, enabling uniform thermal dissipation (RthJA = 400 K/W on >16 mm² pad) and mechanical robustness across -40 °C to +100 °C operating range. Luminous intensity grouping (IVmax/IVmin ≤ 1.6 per unit) ensures visual consistency in multi-LED assemblies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | ≥4.0 mcd at 10 mA - ensures visibility under typical indicator backlighting conditions |
| Dominant wavelength | 466 nm - defines precise blue color point compliant with automotive display standards |
| Forward voltage | 3.9–4.5 V at 20 mA - determines minimum supply headroom and series resistor sizing |
| Viewing angle | ±60° - supports wide-angle illumination for switch and symbol backlighting |
| Thermal resistance | 400 K/W - sets maximum allowable ambient temperature for 20 mA continuous operation |
| ESD rating | Class 1 - requires handling precautions during SMT assembly and board handling |
| Max forward current | 20 mA DC - defines absolute steady-state drive limit without derating |
Pinout & Package
TLMB3100-GS08 uses a 2-pin PLCC-2 surface-mount package (equivalent footprint to size B tantalum capacitor), with molded white thermoplastic body and exposed lead-frame terminals. Pin identification follows standard PLCC-2 orientation: Pin 1 (anode) and Pin 2 (cathode), marked by cathode notch on package top edge.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Positive terminal requiring current-limiting resistor when driven from 3.3 V or 5 V logic rails |
| Pin 2 | Cathode | Negative terminal connected to ground or low-side switch; marked by physical notch on package |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar blue LED emitter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OSMBA5190Z | Higher luminous intensity (7–12 mcd), same PLCC-2 package, 470 nm dominant wavelength | Better suited for high-brightness indicator use where tighter color tolerance is not required | Select OSMBA5190Z when higher output is needed and 4 nm wavelength shift is acceptable |
| LTST-C191KSKT | Same 465 nm dominant wavelength, 0805 package (smaller footprint), 3.5–7.0 mcd intensity range | Requires PCB layout change; lower thermal mass limits max continuous current to 25 mA | Choose LTST-C191KSKT only if space-constrained designs prioritize footprint over thermal margin |
Compared with TLMB3100-GS08, OSMBA5190Z offers higher intensity but looser wavelength control, while LTST-C191KSKT reduces board area at the cost of thermal derating capability and requires re-layout-neither is pin-compatible.

FAQ
What is the maximum continuous forward current for TLMB3100-GS08?
The TLMB3100-GS08 has a maximum DC forward current rating of 20 mA at ambient temperatures ≤60 °C. Exceeding this value without thermal derating risks accelerated lumen depreciation and potential junction failure. The device must be mounted on a PCB pad >16 mm² to achieve the specified 400 K/W thermal resistance and sustain rated current across its full -40 °C to +100 °C operating range.
Does TLMB3100-GS08 require a current-limiting resistor in series?
Yes, TLMB3100-GS08 requires an external current-limiting resistor when driven from common logic supplies (e.g., 3.3 V or 5 V). With a forward voltage range of 3.9–4.5 V at 20 mA, a typical 5 V supply would need a ~25 Ω resistor to maintain nominal 20 mA drive, while a 3.3 V supply may only support ~10 mA without exceeding VF-designers must calculate based on actual VF bin and target current.
Is TLMB3100-GS08 compatible with lead-free reflow processes?
Yes, TLMB3100-GS08 is fully compatible with lead-free infrared, vapor-phase, and wave soldering processes per CECC standards. Its package withstands peak soldering temperatures up to 260 °C for ≤5 seconds. The device is Pb-free and RoHS-compliant, with no internal lead-based solder or terminations that could compromise joint integrity during high-temperature reflow.
What does the "GS08" suffix indicate in TLMB3100-GS08?
The "GS08" suffix in TLMB3100-GS08 denotes Vishay's standard 8 mm tape-and-reel packaging format with 1000 units per reel. This packaging enables automated pick-and-place assembly and conforms to EIA-481-D standards. The "GS" prefix indicates general-purpose SMD packaging, while "08" specifies the 8 mm carrier tape width-distinct from bulk or ammo-pack variants.
How is luminous intensity grouping implemented for TLMB3100-GS08?
Luminous intensity grouping for TLMB3100-GS08 is performed at wafer sort and final test: devices are binned so that the ratio of maximum-to-minimum intensity (IVmax/IVmin) within each 8 mm tape reel is ≤1.6 at 10 mA. This ensures visual uniformity across LEDs used in the same assembly-critical for backlighting panels and multi-segment displays where mismatched brightness would degrade user experience.
