Product details
Overview
VLDS1535G-08 from Vishay Semiconductors is a super red dome lens SMD LED using AlInGaP-on-Si chip technology, delivering 2800–9000 mcd luminous intensity at 50 mA, with dominant wavelength 626–637 nm and ±22° viewing angle. It supports DC forward current up to 70 mA and operates across –40 °C to +100 °C ambient temperature, suited for high-reliability indicator and signage applications.
For engineers reviewing the VLDS1535G-08 datasheet, VLDS1535G-08 pinout, VLDS1535G-08 application, or VLDS1535G-08 equivalent, key selection factors include luminous intensity binning (CA–EA groups), forward voltage range (1.9–2.7 V), ESD withstand (2 kV HBM), reflow compatibility per J-STD-020, and gullwing surface-mount package dimensions (2.3 × 2.3 × 2.6 mm).
Technical Context
This super red LED employs AlInGaP-on-Si die architecture optimized for high luminous flux and stable chromaticity under DC drive. Its gullwing leadframe enables robust thermal dissipation (RthJA = 325 K/W) and supports peak reflow temperatures up to 260 °C.
The device features tight optical control: ±22° half-intensity angle, spectral bandwidth ≤18 nm, and dominant wavelength tolerance of ±1 nm. Luminous intensity ratio within each reel is capped at IVmax/IVmin ≤ 1.6, ensuring consistent brightness grouping for visual uniformity in multi-LED arrays.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Luminous intensity | 2800–9000 mcd at 50 mA - defines visible brightness level for human-perceived indicators under standard drive conditions |
| Dominant wavelength | 626–637 nm - specifies super red chromaticity compliant with traffic signal and safety signage color standards |
| Forward voltage | 1.9–2.7 V at 50 mA - determines minimum supply headroom and series resistor sizing in constant-current driver designs |
| Viewing angle | ±22° half-intensity - sets beam spread for directional visibility in panel-mounted indicators and segmented displays |
| DC forward current | 70 mA max at Tamb ≤ 60 °C - establishes maximum continuous drive capability before thermal derating applies |
| ESD withstand | 2 kV HBM (JESD22-A114-B) - indicates handling robustness during PCB assembly without additional protection circuitry |
| Thermal resistance | 325 K/W junction-to-ambient - quantifies self-heating impact on lumen maintenance and lifetime at rated current |
Pinout & Package
VLDS1535G-08 uses a gullwing surface-mount package (2.3 × 2.3 × 2.6 mm) with exposed copper thermal pad and molded dome lens. Cathode and anode terminals are identified by physical pin location and marking on the package body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Positive DC input terminal | Connected to constant-current source or current-limiting resistor; polarity must be observed to avoid reverse breakdown |
| Cathode | Negative DC return terminal | Typically tied to ground or low-side switch; serves as thermal path via exposed copper pad on PCB |
Key Features
| Feature | Design Value |
|---|---|
| Gullwing SMD package | Enables automated placement and reflow soldering per J-STD-020, with mechanical stability for vibration-prone environments |
| Luminous intensity binning | IVmax/IVmin ≤ 1.6 per reel ensures uniform brightness across LEDs used in adjacent positions of status panels |
| AlInGaP-on-Si die technology | Delivers high radiant efficiency and stable color point over temperature (Δλ < 8 nm from –40 °C to +100 °C) |
| JEDEC Level 2a preconditioning | Validates moisture sensitivity compliance for standard factory handling prior to reflow |
| Clear untinted dome lens | Maximizes light extraction and preserves color fidelity without diffusion-induced saturation loss |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super red LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VLDS1535R-08 | Same package and electrical specs, but rated as "super red" with identical 626–637 nm λd and 2800–9000 mcd IV | No functional difference; R-suffix denotes same optical binning structure as G-suffix variant | Select when sourcing consistency across mixed-color VLD.1535 family reels is required |
| VLDR1535G-08 | Higher luminous intensity (3550–11200 mcd), narrower dominant wavelength range (619–631 nm), same VF and package | Better suited for applications demanding higher brightness or tighter red chromaticity, e.g., automotive interior lighting | Choose when >6500 mcd typical output is needed and 619–631 nm red is acceptable instead of super red |
Compared with VLDS1535G-08, VLDS1535R-08 offers identical photometric performance and binning, while VLDR1535G-08 trades broader wavelength tolerance for +30% typical intensity - enabling higher visibility where color precision is secondary to luminance.

FAQ
What is the maximum DC forward current rating for VLDS1535G-08?
The VLDS1535G-08 has a maximum DC forward current of 70 mA at ambient temperatures ≤ 60 °C. Above this temperature, derating is required per Fig. 1 in the datasheet. Exceeding 70 mA continuously risks accelerated lumen depreciation and junction overheating beyond the 125 °C limit. Always verify thermal design with RthJA = 325 K/W when using VLDS1535G-08 in enclosed assemblies.
Does VLDS1535G-08 support lead-free reflow soldering?
Yes, VLDS1535G-08 is qualified for lead-free reflow per J-STD-020, with a peak temperature of 260 °C for ≤ 10 seconds. The recommended profile includes ramp-up ≤ 3 °C/s, time above 217 °C ≤ 30 s, and cooling rate ≤ 6 °C/s. Preconditioning to JEDEC Level 2a ensures moisture sensitivity is managed before reflow. Always use VLDS1535G-08 within its specified dry-packaging window.
What does the "-08" suffix indicate in VLDS1535G-08?
The "-08" suffix in VLDS1535G-08 denotes the tape-and-reel packaging configuration: 1500 pieces per reel, with EIA-481-compliant carrier tape, 8 mm width, and standard leader/trailer lengths. It does not indicate optical binning or electrical variant - all VLDS1535G-08 units share the same super red chromaticity and luminous intensity range (2800–9000 mcd), grouped per IVmax/IVmin ≤ 1.6.
How is luminous intensity binned for VLDS1535G-08?
VLDS1535G-08 is binned into luminous intensity groups CA through EA per the datasheet table, with CA = 2800–3550 mcd and EA = 7100–9000 mcd. Each reel contains only one intensity group - no mixing occurs. Binning is performed at 50 mA, 25 °C, with ±15 % test tolerance. Engineers selecting VLDS1535G-08 must specify the desired group (e.g., VLDS1535G-08-CA) to ensure brightness uniformity across production batches.
Can VLDS1535G-08 be driven in reverse polarity?
No - VLDS1535G-08 is not designed for reverse conduction. The absolute maximum reverse voltage is only 5 V, and reverse operation is explicitly limited to "short term application only" per the datasheet note. Sustained reverse bias risks permanent degradation of the AlInGaP die. Always observe anode/cathode orientation during layout and assembly to prevent damage to VLDS1535G-08.
