Product details
Overview
TLMH3101-GS08 from Vishay Semiconductors is a surface-mount red LED in PLCC-2 package, with luminous intensity 4–12.5 mcd at 10 mA, dominant wavelength 612–625 nm, and ±60° viewing angle - designed for indicator and backlighting applications in automotive dashboards and office equipment.
For engineers reviewing the TLMH3101-GS08 datasheet, TLMH3101-GS08 pinout, TLMH3101-GS08 application, or TLMH3101-GS08 equivalent, key selection criteria include luminous intensity binning (IVmax/IVmin ≤ 1.6 per tape unit), low-profile PLCC-2 footprint compatibility with IR/vapor-phase soldering, and GaAsP-on-GaP chip technology enabling stable red emission under 30 mA DC forward current.
Technical Context
The TLMH3101-GS08 uses a GaAsP-on-GaP epitaxial structure emitting in the red spectrum (λd = 612–625 nm), housed in a white thermoplastic PLCC-2 package with clear epoxy lens and integrated reflector. Its non-diffused lens enables efficient coupling to light pipes and LCD backlights.
Rated for 30 mA DC forward current and 6 V reverse voltage, it operates across –40 °C to +100 °C ambient temperature with thermal resistance RthJA = 400 K/W on ≥16 mm² PCB pad. Luminous intensity is binned per tape unit to ensure IVmax/IVmin ≤ 1.6, supporting consistent visual performance in multi-LED arrays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 4–12.5 mcd at 10 mA - defines visible brightness level for human-perceptible indicators and backlighting |
| Dominant wavelength | 612–625 nm - ensures consistent red chromaticity compliant with automotive and telecom visual signaling standards |
| Viewing angle | ±60° - provides wide, uniform illumination suitable for panel-mounted indicators and edge-lit symbols |
| Forward voltage | 2.0–2.8 V at 20 mA - determines minimum supply headroom and series resistor sizing in constant-current drive circuits |
| Absolute max forward current | 30 mA at Tamb ≤ 60 °C - sets upper limit for continuous operation without derating or thermal runaway |
| Junction capacitance | 15 pF at 0 V, 1 MHz - impacts high-frequency PWM dimming response and signal integrity in fast-switched applications |
| Thermal resistance | 400 K/W on ≥16 mm² pad - quantifies thermal path efficiency; requires adequate copper area to sustain 100 mW power dissipation |
Pinout & Package
Package: PLCC-2 (SMD, low-profile, 3.5 mm × 2.8 mm body, 2.2 mm height), equivalent to size B tantalum capacitor footprint; lead-free (e3) construction, compatible with infrared, vapor-phase, and wave soldering per CECC standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (A) | Positive LED terminal | Connected to current source or series resistor; polarity must be observed to avoid reverse breakdown at 6 V |
| Cathode (K) | Negative LED terminal | Typically tied to ground or current sink; forms return path for forward conduction; exposed metal frame aids thermal conduction |
Key Features
| Feature | Design Value |
|---|---|
| Non-diffused lens | Enables precise optical coupling to light guides and edge-lit LCDs without scattering loss |
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 per tape unit - ensures uniform brightness across production batches for consistent UI appearance |
| PLCC-2 footprint | Standardized EIA/ICE package - supports automated pick-and-place and reflow compatibility across SMT lines |
| Low power consumption | 100 mW max power dissipation at 30 mA - reduces thermal load in dense indicator arrays and battery-powered devices |
| Lead (Pb)-free construction | e3 termination per J-STD-609 - meets RoHS compliance requirements without compromising solderability or reliability |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLMH3102-GS08 | Higher luminous intensity range: 6.3–20 mcd at 10 mA; otherwise identical package, wavelength, and ratings | Better suited for applications requiring higher brightness in ambient-lit environments or longer viewing distances | Select when >12.5 mcd minimum intensity is required; same PCB layout and drive circuitry apply |
| TLMO3101-GS08 | Soft orange emission (λd = 598–611 nm); identical intensity range (4–12.5 mcd), package, and electrical specs | Used where warm-orange color improves user perception vs. red (e.g., standby vs. active states) | Choose for color-differentiated signaling; requires no design change except optical filter or overlay adjustment |

FAQ
What is the maximum continuous forward current rating for TLMH3101-GS08?
The TLMH3101-GS08 has a DC forward current rating of 30 mA at ambient temperatures ≤60 °C. Exceeding this value without thermal derating risks exceeding the 100 °C junction temperature limit and accelerated lumen depreciation. The TLMH3101-GS08 must be mounted on a PCB pad ≥16 mm² to achieve the specified 400 K/W thermal resistance and sustain rated current.
Does TLMH3101-GS08 require current-limiting circuitry?
Yes, the TLMH3101-GS08 requires external current limiting - either a series resistor or constant-current driver - because its forward voltage varies between 2.0 V and 2.8 V at 20 mA. Without regulation, supply voltage fluctuations would cause significant luminous intensity variation and potential overcurrent stress. The TLMH3101-GS08 is not internally regulated.
Is TLMH3101-GS08 compatible with lead-free reflow soldering processes?
Yes, the TLMH3101-GS08 is qualified for lead-free reflow, including infrared and vapor-phase soldering per CECC standards, with peak solder temperature up to 260 °C for ≤5 seconds. Its e3 (lead-free) terminations and thermoplastic package withstand standard Pb-free thermal profiles without delamination or lens discoloration.
What does the "GS08" suffix indicate in TLMH3101-GS08?
The "GS08" suffix denotes packaging: 8 mm carrier tape, 1000 pieces per reel, and standard moisture sensitivity level (MSL) 1 - meaning unlimited floor life at ≤30 °C/60% RH. This format ensures compatibility with high-speed automated placement equipment and simplifies inventory handling for the TLMH3101-GS08 in production environments.
How is luminous intensity binned for TLMH3101-GS08?
TLMH3101-GS08 is binned so that within each 8 mm tape unit, the ratio of maximum to minimum luminous intensity (IVmax/IVmin) is ≤1.6 at 10 mA. This tight binning ensures visual uniformity across LEDs used in the same assembly - critical for multi-LED indicators and backlighting where mismatched brightness would degrade user interface quality. The TLMH3101-GS08 achieves this via post-package test sorting.
