Applications
TSFF5210 is used in proximity sensors, IR remote controls, and short-range optical data link transmitters where a focused 870 nm, +/-10 degree beam with 180 mW/sr intensity is needed to maximize signal at the receiver across distances of centimeters to meters. The high-reliability T-1.75 through-hole package makes it suitable for industrial automation light barriers, security motion detectors, and optically triggered counters in harsh-environment applications.

Frequently Asked Questions
What is the emission wavelength and beam angle of TSFF5210?
TSFF5210 emits at 870 nm in the near-infrared spectrum with a narrow half-angle of +/-10 degrees, producing a focused beam with a radiant intensity of 180 mW/sr. The 870 nm wavelength falls within the peak sensitivity range of most silicon PIN photodiodes and phototransistors, making it efficient for short-range optical sensing and IR transmission systems.
What are the maximum forward current and forward voltage ratings for TSFF5210?
TSFF5210 has a maximum forward current of 100 mA (0.1 A) and a maximum forward voltage of 1.8 V. At these ratings, the nominal output power is 50 mW. A series current-limiting resistor is required when driving TSFF5210 from a 3.3 V or 5 V digital output to keep the forward current within the 100 mA maximum specification and prevent LED damage.
Why is TSFF5210 preferred for industrial light-barrier applications over wider-angle IR LEDs?
TSFF5210's narrow +/-10 degree beam concentrates all 180 mW/sr of radiant intensity into a tight cone, enabling reliable detection across greater distances than an IR LED with a wide 30-60 degree half-angle that spreads the same optical power over a much larger solid angle. In industrial light barriers and laser-replacement proximity sensors, this focused emission reduces false triggering from ambient infrared and stray reflections, improving system reliability.
Is TSFF5210 compatible with standard silicon photodetectors?
Yes, TSFF5210 emits at 870 nm, which is well-matched to the spectral sensitivity peak of standard silicon PIN photodiodes (typically 900-950 nm) and silicon phototransistors (typically 800-950 nm). This wavelength match maximizes the photocurrent generated per milliwatt of incident IR power, enabling efficient data links at 50 mW nominal output and reducing the receiver amplifier gain needed for reliable detection at distances of 1 meter or more.
