Product details
Overview
VLDY1535G-08 from Vishay Semiconductors is a yellow dome-lens surface-mount LED using AlInGaP-on-Si chip technology, delivering 4500–14 000 mcd luminous intensity at 50 mA, with dominant wavelength 583–595 nm and ±22° viewing angle - designed for high-brightness indicator and backlighting in industrial signage and consumer displays.
For engineers reviewing the VLDY1535G-08 datasheet, VLDY1535G-08 pinout, VLDY1535G-08 application, or VLDY1535G-08 equivalent, key selection criteria include forward voltage (1.9–2.7 V), thermal resistance (325 K/W), ESD rating (2 kV), reflow compatibility per J-STD-020, and gullwing/reverse gullwing package geometry.
Technical Context
The VLDY1535G-08 employs an AlInGaP-on-Si die optimized for yellow emission, with peak wavelength at 591 nm and spectral bandwidth of 17 nm at 50% relative intensity. Its optical design features a molded clear dome lens enabling ±22° half-intensity beam angle and high directionality.
Electrically, it supports DC forward current up to 70 mA at ≤60 °C ambient, with absolute maximum reverse voltage of 5 V (short-term only). Thermal performance is characterized by junction-to-ambient resistance of 325 K/W when mounted on ≥16 mm² copper pad.

Equivalent & Alternatives
The following parts are listed as comparable options for similar yellow LED applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Kingbright APT1608SYCK | Smaller 1.6 × 0.8 mm 0603 package; 4300–7000 mcd; VF 2.0–2.4 V; ±30° viewing angle | Better suited for space-constrained PCBs but lower max intensity and wider beam compromises long-distance visibility | Select for compact layouts where intensity >7000 mcd is not required and viewing angle tolerance is relaxed |
| Lumileds LXML-PWC2-0150 | Higher-power 150 mA rated; 12 000–20 000 mcd; VF 2.2–2.6 V; ±25°; requires thermal pad and heatsinking | Designed for active cooling and higher drive currents - overqualified for standard indicator use | Choose only when system-level thermal management supports >100 mA operation and brightness exceeds 14 000 mcd |
Compared with VLDY1535G-08, APT1608SYCK offers smaller size at cost of intensity and beam control, while LXML-PWC2-0150 delivers higher output but demands additional thermal design effort and drive circuitry - making VLDY1535G-08 optimal for cost-sensitive, thermally constrained indicator applications.

FAQ
What is the maximum continuous forward current for VLDY1535G-08?
The VLDY1535G-08 supports a maximum DC forward current of 70 mA when ambient temperature is ≤60 °C. At higher ambient temperatures, derating is required per Figure 1 in the datasheet; operation above 70 mA risks accelerated lumen depreciation and thermal runaway. The VLDY1535G-08 must be mounted on a PCB pad ≥16 mm² to maintain safe junction temperature.
Does VLDY1535G-08 require baking before reflow soldering?
No - the VLDY1535G-08 is preconditioned to JEDEC Level 2a and shipped in dry-packed anti-humidity bags. If the sealed bag remains unopened and stored <40 °C/<90% RH, the device may be reflowed directly per the J-STD-020 profile. Once opened, use within 672 hours at <30 °C/<60% RH or store in <10% RH dry box to avoid baking.
What does the "-08" suffix indicate in VLDY1535G-08?
The "-08" suffix in VLDY1535G-08 denotes the specific packaging variant: tape-and-reel format with 1500 pieces per reel, conforming to EIA-481-D carrier tape specifications. It also indicates gullwing leadform (drawing 6.544-5408.01-4) and standard halogen-free, RoHS-compliant terminations.
Can VLDY1535G-08 be used in reverse-bias configurations?
VLDY1535G-08 permits reverse voltage up to 5 V, but only for short-term applications as explicitly noted in the datasheet. Continuous or repeated reverse bias risks permanent degradation of the AlInGaP die. For bidirectional signaling, external protection diodes or dedicated AC-driven LED solutions are recommended instead of relying on reverse conduction of the VLDY1535G-08.
How is luminous intensity binned for VLDY1535G-08?
VLDY1535G-08 is binned by luminous intensity into groups CA through FA per the datasheet table, with each reel containing only one intensity group (e.g., DA = 4500–5600 mcd). The IVmax/IVmin ratio per reel is ≤1.6, ensuring predictable brightness matching across LEDs used in the same assembly - critical for uniform appearance in multi-LED arrays.
