ams OSRAM SFH 4726AS A01 OSLON® Black 940nm High-Power Stealth IR LED

Introduction

The ams OSRAM OSLON® Black SFH 4726AS A01 represents a strategic performance benchmark for manufacturers who require intense radiant power and a wide-angle light distribution within a compact footprint. Operating at a centroid wavelength of 940 nm, this emitter is the gold standard for "stealth" applications where a visible red glow must be eliminated-a critical requirement for automotive driver monitoring systems (DMS) and high-security surveillance.

For LED module manufacturers and fixture designers, the A01 version of the SFH 4726AS offers enhanced reliability and consistent binning. Its integrated silicone lens provides a 150-degree viewing angle, facilitating perfectly uniform infrared coverage across a broad field of view (FOV). This architecture eliminates the "hot spot" center common in narrow-beam emitters, allowing fixture manufacturers to reduce the total component count while maintaining an even signal for modern CMOS sensors.

Key Product Features

• 940nm Covert Performance: Specifically binned for applications requiring total invisibility to the human eye. This wavelength ensures that security cameras and cabin sensors remain undetectable, meeting the strict standards of government and automotive tiers.
• Exceptional 150° Wide-Angle Optics: The flat-top package combined with a wide-angle lens facilitates superior light extraction. It provides the "flood" illumination needed for close-range biometrics and interior occupancy sensing without requiring bulky secondary diffusers.
• Automotive-Grade Reliability (AEC-Q102): Built on the high-power OSLON® Black ceramic platform, the SFH 4726AS A01 is designed to withstand extreme thermal cycling and high-vibration environments, preserving the L70 lifespan in 24/7 mission-critical hardware.
• Superior Thermal path: Featuring a junction-to-solder point thermal resistance of typically 5.3 K/W, this component ensures efficient heat transfer to the MCPCB. This prevents thermal runaway and maintains radiant flux stability during high-current operation.
• High Current Drive Capability: Engineered for both continuous and pulsed operation, handling DC currents up to 1500 mA and pulses up to 5A, facilitating massive radiant intensity for high-speed synchronized sensors.

The SFH 4726AS A01 is a staple light source for:

• Automotive DMS & Cabin Sensing: Stealth illumination for eye-tracking and fatigue detection sensors requiring AEC-Q102 certification.
• Covert CCTV Surveillance: High-intensity broadband floodlighting for security cameras where high contrast is needed without a visible light footprint.
• Biometric Identification: Reliable 940nm source for wide-angle facial recognition and iris scanning in secure facility hardware.
• Gesture Recognition & Robotics: Compact light engines for human-machine interface (HMI) sensors and industrial robotic spatial mapping.
• Industrial Machine Vision: Saturated IR emitters for high-speed automated inspection lines requiring wide field-of-view coverage.
