Brief Description

This advanced 3535 series infrared LED features an innovative dual-stack chip design that delivers stable 3V operating voltage, eliminating the need for complex voltage conversion circuits and simplifying system design. Available in 850nm and 940nm wavelength options, it provides industry-leading radiant power up to 800mW at 700mA driving current. Encapsulated in a high-thermal-conductivity ceramic substrate with a high-transmittance hemispherical dome lens, it offers uniform 120° wide-beam output and excellent heat dissipation performance. This high-power infrared emitter is the ideal core light source for long-range security surveillance, AR/VR eye tracking systems, medical phototherapy equipment and industrial optical sensing applications.

Core Competitive Advantages

1. Innovative Dual-Stack Chip 3V High-Voltage Design

Unique dual stacked chip architecture achieves 3V forward voltage, significantly simplifying power supply design by eliminating the need for step-down conversion circuits. This reduces system component count, lowers overall cost and improves power efficiency compared to conventional 1.5V infrared LEDs.

2. Industry-Leading High Radiant Power Output

Delivers exceptional radiant flux up to 800mW (850nm) and 700mW (940nm) at 700mA operating current, providing strong infrared penetration capability for long-range surveillance and deep tissue medical phototherapy applications.

3. Premium Ceramic Package for Superior Thermal Management

High-purity alumina ceramic substrate provides excellent heat dissipation performance, effectively reducing junction temperature during continuous high-power operation, minimizing light decay and extending service life to over 50,000 hours.

4. Two Optimized Wavelength Options for Diverse Applications

850nm: Features weak visible red glow, ideal for camera focusing debugging and conventional long-range night vision surveillance;

940nm: Completely invisible infrared spectrum, perfect for covert surveillance, AR/VR eye tracking and non-intrusive medical detection.

5. 120° Dome Lens for Uniform Wide-Area Irradiation

High-transmittance hemispherical silicone dome lens delivers seamless 120° wide beam angle with uniform infrared distribution, eliminating hot spots and ensuring consistent performance across large monitoring areas and treatment surfaces.

6. Standard 3535 Industry Footprint for Automated Production

Universal 3.45×3.45×2.36mm package size is fully compatible with all automatic SMT pick-and-place equipment, simplifying PCB layout design and reducing assembly cost for mass production.
