Product details
Overview
VLDTG1232R-08 from Vishay Semiconductors is a true green dome lens SMD LED using InGaN-on-sapphire chip technology, delivering 7100–16,000 mcd luminous intensity at 20 mA, with dominant wavelength 515–541 nm, forward voltage 2.6–3.4 V, and ±9° viewing angle - designed for high-visibility indicator and backlighting applications in industrial and consumer devices.
For engineers reviewing the VLDTG1232R-08 datasheet, VLDTG1232R-08 pinout, VLDTG1232R-08 application, or VLDTG1232R-08 equivalent, this page provides verified optical and electrical specifications, package geometry, binning classification, thermal limits, and reflow compatibility per J-STD-020 and JEDEC Level 2a.
Technical Context
This device is a surface-mount, gullwing or reverse gullwing packaged LED with a molded clear dome lens optimized for directional light emission. Its ±9° half-intensity angle and 0.35 mlm/mcd luminous flux-to-intensity ratio support focused illumination in space-constrained layouts.
It operates at 20 mA nominal forward current with absolute maximum ratings of 30 mA DC, 100 mW power dissipation, and 100 °C junction temperature. Thermal resistance junction-to-ambient is 400 K/W when mounted on a PCB pad >16 mm².
Key Specifications

| Cathode | Negative terminal | Connected to ground or current sink; marked by notch or chamfer on package edge |
Key Features
| Feature | Design Value |
|---|---|
| InGaN-on-sapphire chip | Delivers stable true green output with minimal wavelength shift over temperature and lifetime |
| Luminous intensity binning | Groups EA–GB ensure consistent brightness across reels; no mixing of intensity bins per reel |
| JEDEC Level 2a preconditioning | Qualified for lead-free reflow per J-STD-020, enabling compatibility with standard SMT lines |
| Clear dome lens | Optimizes light extraction and directional control without secondary optics or diffusers |
| ESD protection | 2 kV HBM rating reduces risk of field failure during handling and board assembly |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar true green LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLDTG1232G-08 | Same package, same optical specs, but gullwing leadform (vs. reverse gullwing for VLDTG1232R-08) | Requires different PCB footprint and stencil design; identical luminous intensity and wavelength bins | Select based on board layout constraints and existing gullwing vs. reverse gullwing assembly infrastructure |
| TLHG5200 from Toshiba | True green SMD LED, 525 nm typ., 8000–12,000 mcd at 20 mA, ±10° viewing angle, 2.8–3.4 V VF | Slightly wider viewing angle and higher VF tolerance; not binned to same intensity group granularity | Use where tighter intensity matching is not required and broader beam is acceptable for diffuse indicator use |
Compared with VLDTG1232R-08, VLDTG1232G-08 offers identical optical performance but demands a different PCB land pattern, while TLHG5200 provides comparable true green output with relaxed binning and wider angular distribution - making it suitable for non-critical visibility applications where layout flexibility or cost optimization is prioritized.

FAQ
What is the dominant wavelength range for VLDTG1232R-08?
The dominant wavelength range for VLDTG1232R-08 is 515–541 nm at 20 mA forward current, placing it firmly in the true green spectrum. This range is verified per the Vishay datasheet Document Number 80003, Rev. 1.0, and corresponds to Group 3–6 color binning classifications defined for the VLDTG1232 series. The typical value is 525 nm.
Is VLDTG1232R-08 compatible with lead-free reflow soldering?
Yes, VLDTG1232R-08 is qualified for lead-free reflow soldering per J-STD-020 and preconditioned to JEDEC Level 2a. Its maximum peak temperature rating is 260 °C for ≤100 s, with ramp rates limited to 3 °C/s (up) and 6 °C/s (down). The recommended profile matches Vishay's Figure 14 Reflow Soldering Profile.
What is the luminous intensity binning structure for VLDTG1232R-08?
VLDTG1232R-08 is categorized into luminous intensity groups EA through GB, with EA = 7100–9000 mcd and GB = 22,400–28,000 mcd. Each reel contains only one intensity group - no mixing occurs - ensuring consistent brightness across production lots. This binning is specified in the "LUMINOUS INTENSITY CLASSIFICATION – TRUE GREEN" table of the datasheet.
Does VLDTG1232R-08 have an integrated resistor or require external current limiting?
VLDTG1232R-08 is a bare LED die in a molded package and does not include an integrated current-limiting resistor. It requires an external series resistor or constant-current driver to operate safely at its rated 20 mA forward current. The forward voltage range of 2.6–3.4 V at 20 mA must be used to calculate appropriate limiting impedance.
What is the maximum allowable reverse voltage for VLDTG1232R-08?
The absolute maximum reverse voltage for VLDTG1232R-08 is 5 V, and operation in reverse bias is permitted only for short-term applications per Note (1) in the datasheet. Sustained reverse voltage or current exceeding this limit risks irreversible degradation of the InGaN chip junction.
