Product details
Overview
TLMB2100-GS08 from Vishay Semiconductors is a blue surface-mount LED with 7.0 mcd typical luminous intensity at 10 mA, 465 nm dominant wavelength, ±60° viewing angle, and 3.9–4.5 V forward voltage at 20 mA. It features a low-profile 2.3 mm × 1.3 mm × 1.4 mm Mini SMD package, non-diffused lens for efficient light-pipe coupling, and Pb-free construction.
For engineers reviewing the TLMB2100-GS08 datasheet, TLMB2100-GS08 pinout, TLMB2100-GS08 application, or TLMB2100-GS08 equivalent, key selection criteria include forward voltage tolerance, luminous intensity binning (IVmax/IVmin ≤ 2.0), thermal resistance (480 K/W), operating temperature range (−40 to +100 °C), and compatibility with IR reflow soldering per IPC-9501.
Technical Context
The TLMB2100-GS08 is a GaN-based blue LED optimized for indicator and backlighting applications requiring consistent chromaticity and directional emission. Its ±60° half-intensity angle and non-diffused lens enable precise optical coupling in space-constrained layouts.
Rated for 20 mA DC forward current and 5 V reverse voltage, it operates reliably across −40 to +100 °C ambient temperature with junction-to-ambient thermal resistance of 480 K/W when mounted on a PCB pad >5 mm² - critical for thermal management in automotive dashboards and industrial control panels.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4.0–7.0 mcd at 10 mA - ensures visibility under ambient lighting while minimizing power draw |
| Dominant wavelength | 465 nm - defines true blue color point compliant with CIE 1931 chromaticity requirements |
| Forward voltage | 3.9–4.5 V at 20 mA - determines driver voltage headroom and series-resistor sizing |
| Viewing angle | ±60° - provides wide yet controlled illumination suitable for panel backlighting |
| Reverse voltage | 5 V - sets maximum allowable reverse-bias margin during transient conditions |
| Thermal resistance | 480 K/W - informs PCB copper area requirements to maintain Tj ≤ 100 °C |
| Package dimensions | 2.3 mm × 1.3 mm × 1.4 mm - enables high-density placement on compact PCBs |
Pinout & Package
TLMB2100-GS08 uses a 2-pin surface-mount MiniLED package with anode and cathode terminals. The device has no internal polarity marking; orientation is defined by the standard SMD LED footprint with cathode indicated by a chamfered corner or notch on the package body per EIA/ICE standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive terminal | Connected to current-limiting resistor or constant-current driver output; must be biased ≥3.9 V above cathode for conduction |
| Cathode (K) | Negative terminal | Typically tied to ground or low-side switch; marked by physical notch/chamfer on package per JEDEC MO-230AB |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables >90% optical coupling efficiency into light pipes and edge-lit LCD backlights |
| Luminous intensity binning | IVmax/IVmin ≤ 2.0 within tape unit - reduces brightness matching effort in multi-LED arrays |
| Lead (Pb)-free construction | Complies with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 2 |
| IR reflow compatible | Withstands peak solder temperature of 245 °C per IPC-9501 - supports automated assembly without degradation |
Applications
| Automotive Dashboard Backlighting | Office Equipment Indicators |
|---|---|
Use Scenario: Illuminating segmented symbols and icons on instrument cluster overlays under variable cabin lighting. IC Role / Device Role / Timing Role: Discrete blue light source driven by constant-current LED driver ICs such as MAX16820 or TPS6106x. Use Value: 465 nm dominant wavelength delivers high contrast against white/grey dashboard surfaces, while ±60° viewing angle ensures uniform symbol illumination without hotspots. | Use Scenario: Status indication for power-on, network activity, and error states on multifunction printers and scanners. IC Role / Device Role / Timing Role: Standalone visual feedback element interfaced directly to microcontroller GPIO pins via current-limiting resistors. Use Value: Low 20 mA drive requirement and 3.9–4.5 V forward voltage simplify interface design and reduce MCU I/O loading versus higher-VF alternatives. |
| Telecom Keypad Backlighting | A/V Equipment Symbol Illumination |
Use Scenario: Edge-lit backlighting for tactile keypads in VoIP phones and fax machines where space is limited. IC Role / Device Role / Timing Role: Primary light source coupled to molded acrylic light guide with precision-cut light-extraction features. Use Value: Non-diffused lens and 2.3 mm × 1.3 mm footprint allow tight placement along keypad perimeter, maximizing light injection into thin light guides. | Use Scenario: Highlighting function buttons and status LEDs on stereo receivers and streaming media players. IC Role / Device Role / Timing Role: Direct-drive indicator LED powered from regulated 5 V or 3.3 V rails using discrete resistive current limiting. Use Value: 7.0 mcd typical intensity at 10 mA ensures legibility in both dark and moderately lit rooms without excessive power consumption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar blue LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTST-C193TBKT | 0805 package (2.0 mm × 1.25 mm), 120 mcd @ 20 mA, 470 nm dominant wavelength, 3.2–3.6 V VF | Higher intensity but wider 130° viewing angle - less suitable for light-pipe coupling | Select when higher brightness and broader viewing are prioritized over optical directionality and board space |
| NSPB300BS | 1206 package (3.2 mm × 1.6 mm), 100 mcd @ 20 mA, 465 nm, 3.0–3.4 V VF, 350 K/W RthJA | Larger footprint and lower thermal resistance - better for continuous high-current operation | Select when thermal performance and long-term reliability under sustained 20 mA drive are critical |
Compared with LTST-C193TBKT and NSPB300BS, TLMB2100-GS08 offers the smallest footprint (2.3 × 1.3 mm) and highest directionality (±60°), making it optimal for space-constrained backlighting where optical control outweighs raw intensity - especially in automotive and telecom interfaces.

FAQ
What is the maximum DC forward current rating for TLMB2100-GS08?
The TLMB2100-GS08 has a maximum DC forward current of 20 mA at ambient temperatures ≤60 °C. Exceeding this value risks accelerated lumen depreciation and junction temperature rise beyond the 100 °C limit. Derating is required above 60 °C per Figure 2 in the datasheet - at 85 °C ambient, max IF drops to ~12 mA. Always verify thermal design with the 480 K/W RthJA value.
Does TLMB2100-GS08 require current-limiting circuitry?
Yes, TLMB2100-GS08 requires external current limiting - either a series resistor or constant-current driver - because its forward voltage varies with temperature and manufacturing spread (3.9–4.5 V at 20 mA). Without regulation, supply voltage fluctuations or thermal drift could cause current runaway and premature failure. A 100 Ω resistor is typical for 5 V drive at 20 mA.
Is TLMB2100-GS08 compatible with lead-free reflow soldering processes?
Yes, TLMB2100-GS08 is qualified for lead-free IR reflow soldering per IPC-9501 with a peak temperature of 245 °C. It meets JEDEC J-STD-020 moisture sensitivity level 2, requiring dry-pack storage and bake-out if exposed to ambient >60% RH for >1 year. The aluminum moisture barrier bag includes a JESD22-A112 level 2 label.
What does the "GS08" suffix indicate in TLMB2100-GS08?
The "GS08" suffix denotes the packaging configuration: GS = 8 mm carrier tape, 08 = 3000 pieces per reel. This matches the EIA-481 standard for SMD component tape-and-reel delivery. The part is supplied in anti-humidity sealed aluminum bags with desiccant and JESD22-A112 level 2 labeling for moisture-sensitive handling.
Can TLMB2100-GS08 be used in reverse-bias configurations?
TLMB2100-GS08 can tolerate short-term reverse bias up to 5 V, as specified in its absolute maximum ratings. However, it is not designed for sustained reverse operation - leakage current increases significantly above 1 V reverse, and prolonged exposure risks junction degradation. Reverse polarity protection must be implemented externally if system-level fault conditions could apply reverse voltage.
