Product details
Overview
TLMH3102-GS08 from Vishay Semiconductors is a surface-mount red LED in PLCC-2 package, with luminous intensity 6.3–20 mcd at 10 mA, dominant wavelength 612–625 nm, and ±60° viewing angle. It delivers high brightness for indicator and backlighting roles in automotive dashboards, telecom devices, and LCD panels.
For engineers reviewing the TLMH3102-GS08 datasheet, TLMH3102-GS08 pinout, TLMH3102-GS08 application, or TLMH3102-GS08 equivalent, this part supports infrared/vapor-phase/wave soldering, meets CECC process compatibility, and offers tight luminous intensity binning (IVmax/IVmin ≤ 1.6 per tape unit) for consistent visual performance across production batches.
Technical Context
This red GaAsP-on-GaP LED operates at 2.0–2.8 V forward voltage under 20 mA drive, with 6 V reverse voltage rating and 15 pF junction capacitance at 0 V/1 MHz. Its thermal resistance is 400 K/W when mounted on a PCB with pad area >16 mm².
The device features a non-diffused lens optimized for coupling to light pipes and flat backlighting, and its PLCC-2 package (equivalent to size B tantalum capacitor) enables automated placement and reflow compatibility per EIA/ICE standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 6.3–20 mcd at 10 mA - ensures visible indication under ambient lighting and uniform backlighting across display segments |
| Dominant wavelength | 612–625 nm - defines true red chromaticity compliant with automotive and telecom visual signaling requirements |
| Viewing angle | ±60° - provides wide, symmetrical light distribution suitable for panel-wide illumination without secondary optics |
| Forward voltage | 2.0–2.8 V at 20 mA - enables direct drive from 3.3 V or 5 V logic rails with minimal series resistance |
| Max DC forward current | 30 mA at Tamb ≤ 60 °C - sets safe continuous operating limit for sustained indicator or backlight duty cycles |
| Junction capacitance | 15 pF at 0 V, 1 MHz - low enough to avoid signal integrity issues in fast-pulsed applications (e.g., multiplexed displays) |
| Thermal resistance | 400 K/W - determines required PCB copper area for thermal management in high-density layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar red LED indicator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLMH3101-GS08 | Luminous intensity 4–12.5 mcd (lower mid-range output) | Better suited for low-power or battery-operated indicators where lower brightness suffices | Select when reduced current draw or softer visual impact is preferred over maximum intensity |
| TLMO3102-GS08 | Soft orange color (598–611 nm dominant wavelength), same IV range and package | Used where warm-tone visual coding is required (e.g., standby vs. active states) | Choose for color differentiation in multi-LED status arrays without changing board layout or drive circuitry |
Compared with TLMH3102-GS08, TLMH3101-GS08 trades peak brightness for lower power use, while TLMO3102-GS08 maintains identical mechanical and electrical interface but shifts chromaticity-enabling functional color variation without redesigning optics or PCB.

FAQ
What is the forward voltage range of the TLMH3102-GS08 at 20 mA?
The TLMH3102-GS08 has a forward voltage range of 2.0 V to 2.8 V when driven at 20 mA. This specification allows direct interfacing with common 3.3 V and 5 V supply rails using a simple series current-limiting resistor. The TLMH3102-GS08's VF tolerance supports predictable power dissipation and thermal behavior in production designs.
Does the TLMH3102-GS08 require special handling during reflow soldering?
No special handling beyond standard Pb-free reflow profiles is required for the TLMH3102-GS08. It is qualified for infrared, vapor phase, and wave soldering per CECC standards, with a maximum soldering temperature of 260 °C for ≤5 seconds. The TLMH3102-GS08's PLCC-2 package and lead-free construction ensure compatibility with IPC/JEDEC J-STD-020 guidelines.
What does the "GS08" suffix indicate in TLMH3102-GS08?
The "GS08" suffix denotes tape-and-reel packaging in 8 mm carrier tape, standard for automated SMT placement. This format aligns with EIA-481 specifications and ensures consistent feeding and positioning during high-speed pick-and-place operations. The TLMH3102-GS08 is supplied in this configuration to support scalable manufacturing without manual handling.
Can the TLMH3102-GS08 be used in automotive under-hood applications?
The TLMH3102-GS08 is rated for an operating temperature range of –40 °C to +100 °C, making it suitable for passenger cabin and dashboard applications. However, it is not qualified for under-hood environments exceeding 100 °C junction temperature. For such locations, derating or alternative high-temp LEDs would be required. The TLMH3102-GS08's thermal resistance (400 K/W) assumes adequate PCB copper area for heat dissipation.
How is luminous intensity binned for the TLMH3102-GS08?
The TLMH3102-GS08 is binned so that the ratio of maximum to minimum luminous intensity (IVmax/IVmin) within a single 8 mm tape unit is ≤1.6. This tight binning ensures consistent brightness across LEDs placed in the same assembly batch, eliminating post-soldering sorting and improving yield in visual-critical applications. The TLMH3102-GS08's specified IV range (6.3–20 mcd) reflects the full production spread, not per-tape variation.
