New Vishay Intertechnology 890 nm IR Emitting Diode Offers High Typical Radiant Intensity of 235 mW/sr and Fast Switching Times of 15 ns
Vishay Intertechnology (NYSE: VSH) has introduced the TSHF5211, a new 890 nm high-speed infrared (IR) emitting diode. This surface emitter technology-based device offers a high typical radiant intensity of 235 mW/sr at 100 mA drive current, which is 50% higher than previous-generation solutions. Key features include:
- Fast switching times of 15 ns
- Low typical forward voltage of 1.5 V
- Narrow ± 10° angle of half intensity
- Excellent -1.0 mV/K temperature coefficient of VF
The TSHF5211 is designed for use in smoke detectors and industrial sensors, offering good spectral matching with silicon photodetectors. It is RoHS-compliant, halogen-free, and Vishay Green. Samples and production quantities are available now, with a 20-week lead time for large orders.
- New IR emitting diode offers 50% higher radiant intensity than previous-generation solutions
- Fast switching times of 15 ns improve performance in target applications
- Excellent temperature coefficient of VF at -1.0 mV/K enhances stability
- Samples and production quantities are immediately available
- 20-week lead time for large orders may impact supply chain efficiency
Built on Surface Emitter Technology, High Speed Device Features Excellent Temperature Coefficient of VF of -1.0 mV/K
MALVERN, Pa., July 17, 2024 (GLOBE NEWSWIRE) -- Vishay Intertechnology, Inc. (NYSE: VSH) is broadening its optoelectronics portfolio with the introduction of a new 890 nm high speed infrared (IR) emitting diode in a clear, untinted leaded plastic package. Based on surface emitter technology, the Vishay Semiconductors TSHF5211 combines an excellent -1.0 mV/K temperature coefficient of VF with higher radiant intensity and faster rise and fall times than previous-generation devices.
The emitter diode released today offers high typical radiant intensity of 235 mW/sr at a 100 mA drive current, which is 50 % higher than previous-generation solutions. With fast switching times of 15 ns, low typical forward voltage of 1.5 V, and a narrow ± 10° angle of half intensity, the device will serve as a high intensity emitter for smoke detectors and industrial sensors. In these applications, the TSHF5211 offers good spectral matching with silicon photodetectors.
RoHS-compliant, halogen-free, and Vishay Green, the device is lead (Pb)-free and capable of lead (Pb)-free soldering up to 260 °C.
Samples and production quantities of the TSHF5211 are available now, with lead times of 20 weeks for large orders.
