Product details
Overview
VLDTG1232RG-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 and ±9° viewing angle - deployed in high-visibility indicator and backlighting applications including LCD symbols and illuminated advertising.
For engineers reviewing the VLDTG1232RG-08 datasheet, VLDTG1232RG-08 pinout, VLDTG1232RG-08 application, or VLDTG1232RG-08 equivalent, this page provides verified optical/electrical specs, package dimensions, thermal limits, binning classification, and reflow-compliant handling guidance for production design-in.
Technical Context
This device operates as a surface-mount light-emitting diode with gullwing or reverse gullwing leadform, rated for 30 mA DC forward current and 100 mW power dissipation at ambient ≤60 °C. Its optical output is binned by luminous intensity (EA–GB groups) and dominant wavelength (515–541 nm), with ESD withstand voltage up to 2 kV per JESD22-A114-B.
Thermal resistance junction-to-ambient is 400 K/W when mounted on a PCB pad >16 mm²; operating temperature range spans −40 °C to +100 °C, and it complies with JEDEC level 2a preconditioning and J-STD-020 reflow profiles - peak 260 °C for ≤100 s.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 7100–16,000 mcd at 20 mA - defines brightness grade for visual detection distance in indicators |
| Dominant wavelength | 515–541 nm - specifies true green color point compliant with IEC 62471 photobiological safety |
| Forward voltage | 2.6–3.4 V at 20 mA - determines driver voltage headroom and power loss in series-string designs |
| Viewing angle | ±9° half-intensity - enables narrow-beam directional indication without secondary optics |
| Thermal resistance | 400 K/W (junction-to-ambient) - sets maximum allowable power dissipation on standard PCB layout |
| ESD rating | 2 kV HBM - informs ESD protection requirements during board assembly and handling |
| Ambient temp. range | −40 °C to +100 °C - supports operation in automotive interior, industrial control, and outdoor signage environments |
Pinout & Package
VLDTG1232RG-08 uses a 2.3 × 2.3 × 2.8 mm SMD dome lens package with gullwing or reverse gullwing leadform. The package exposes copper on the bottom for thermal conduction and includes cathode/anode identification per Vishay drawing No. 6.544-5383.02-4 (gullwing) or 6.544-5391.02-4 (reverse gullwing).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive terminal | Connects to current-limiting resistor or constant-current driver output; polarity must be observed to avoid reverse breakdown |
| Cathode | Negative terminal | Typically tied to ground or low-side switch; marking dot or chamfer identifies cathode side on package |
Key Features
| Feature | Design Value |
|---|---|
| InGaN-on-sapphire chip | Enables high luminous flux and stable green emission under thermal stress vs. older AlInGaP technology |
| Luminous intensity ratio ≤1.6 | Ensures consistent brightness across units within same reel - critical for uniform panel illumination |
| JESD22-A114-B ESD rating | 2 kV HBM tolerance reduces risk of field failure during automated assembly and end-user handling |
| JEDEC level 2a preconditioning | Validates moisture sensitivity level (MSL) compliance for Pb-free reflow without popcorn cracking |
| Reflow-compatible profile | Supports standard J-STD-020 peak temperature (260 °C) and ramp rates - no special soldering process needed |
Applications
| Traffic Signal Indicators | Industrial Panel Backlighting |
|---|---|
Use Scenario: Red/green status indication in pedestrian crossing controllers and vehicle signal modules. IC Role / Device Role / Timing Role: Visual status emitter requiring high on-axis intensity and narrow beam for daylight readability. Use Value: ±9° viewing angle delivers >7100 mcd on-axis intensity at 20 mA - sufficient for 10+ meter visibility in direct sunlight. |
Use Scenario: Illumination of membrane switch legends and LCD segment overlays in factory HMIs. IC Role / Device Role / Timing Role: Directional backlight source aligned with engraved symbols to minimize bleed and maximize contrast. Use Value: True green 515–541 nm output meets human eye photopic response peak - enhances perceived brightness at low drive current. |
| Smoke Detector Status Lights | Illuminated Advertising Panels |
Use Scenario: Low-power, long-life status LED in battery-operated residential smoke alarms. IC Role / Device Role / Timing Role: Steady-state visual alert element with guaranteed minimum intensity over 10-year service life. Use Value: Luminous intensity binning (EA–GB) ensures ≥7100 mcd minimum - maintains visibility through lens aging and dust accumulation. |
Use Scenario: Edge-lit channel letters and logo panels in retail signage requiring saturated green color fidelity. IC Role / Device Role / Timing Role: Primary light source positioned behind diffuser or acrylic guide for uniform color wash. Use Value: Dominant wavelength tolerance (±1 nm) and tight IVmax/IVmin ratio (≤1.6) enable batch-to-batch color and brightness consistency. |
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 | Gullwing leadform only; identical optical/electrical specs and binning structure | Suitable where PCB layout requires standard gullwing footprint and no reverse gullwing clearance constraints | Select VLDTG1232G-08 for conventional SMT placement; VLDTG1232RG-08 when component height or underside clearance is limited |
| TLPG1232G-08 | Same package outline but uses different InGaN epitaxy - typical luminous intensity 6500–15,000 mcd, λd 518–538 nm | Lower intensity ceiling and wider wavelength spread - less suitable for high-uniformity multi-LED arrays | Choose TLPG1232G-08 only if cost sensitivity outweighs need for strict bin-matching and photometric consistency |
Compared with VLDTG1232RG-08, VLDTG1232G-08 offers identical performance in a gullwing-only form factor, while TLPG1232G-08 trades tighter binning control for broader availability - making VLDTG1232RG-08 optimal for applications demanding precise green hue and intensity matching across production batches.

FAQ
What is the maximum forward current rating for VLDTG1232RG-08?
The absolute maximum DC forward current for VLDTG1232RG-08 is 30 mA at ambient temperature ≤60 °C. Exceeding this limit risks accelerated lumen depreciation and potential junction overheating. Derating is required above 60 °C per Fig. 1 in the datasheet - for example, at 85 °C ambient, max IF drops to ~18 mA. Always reference the thermal resistance (400 K/W) and PCB pad size when designing for continuous operation.
Does VLDTG1232RG-08 have a defined anode/cathode marking?
Yes, VLDTG1232RG-08 features physical polarity identification: the cathode is marked by a chamfered corner or dot on the package body, and the anode corresponds to the opposite lead. Vishay's package drawings (No. 6.544-5383.02-4 for gullwing, 6.544-5391.02-4 for reverse gullwing) confirm this orientation. Correct polarity must be maintained to avoid reverse breakdown - VR is rated only 5 V for short-term use.
What does the "RG" suffix in VLDTG1232RG-08 indicate?
The "RG" suffix in VLDTG1232RG-08 denotes "Reverse Gullwing" leadform - distinguishing it from the standard gullwing version (VLDTG1232G-08). This configuration positions the leads bent downward and outward, enabling lower profile mounting and improved clearance beneath the LED body. Both variants share identical optical, electrical, and thermal specifications.
Is VLDTG1232RG-08 compliant with RoHS and halogen-free standards?
Yes, VLDTG1232RG-08 is RoHS-compliant and halogen-free, as confirmed by Vishay's material declarations (Doc. No. 99912) and standard bar code labels showing RoHS and halogen-free symbols. It uses lead (Pb)-free terminations and conforms to JEDEC J-STD-020 reflow profiles - no exemptions or exceptions apply to its environmental compliance status.
How is luminous intensity binned for VLDTG1232RG-08?
VLDTG1232RG-08 is binned into six luminous intensity groups (EA–GB), each with defined min/max mcd ranges - e.g., EA = 7100–9000 mcd at 20 mA. Each reel ships only one intensity group (no mixing), and wavelength is also binned (Groups 3–6, 515–541 nm). Binning codes appear in the SelCode field of the bar code label, enabling traceability to photometric test data per unit.
