Vishay Semiconductors TEFD4300x High-Speed Silicon PIN Photodiodes
Vishay Semiconductors TEFD4300x High-Speed Silicon PIN Photodiodes feature high radiant sensitivity and fast switching times in clear- and black-epoxy T1 plastic packages. Offering 3mm lenses, the TEFD4300 and TEFD4300F feature a high reverse photo current of 17µA and a ±20° angle of half sensitivity. For infrared and visible light sources, the TEFD4300 is a clear epoxy device with a sensitivity range of 350nm to 1120nm. For light sources in the infrared wavelength range of 770nm to 1070nm, the TEFD4300F is a black epoxy device with a daylight blocking filter matched with 850nm to 950nm IR emitters. The photodiodes offer fast switching times down to 10ns at low load resistor values, a low 0.1%/K temperature coefficient of light current, temperature range of -40°C to +100°C, and a 950nm wavelength of peak sensitivity. Vishay Semiconductors TEFD4300x High-Speed Silicon PIN Photodiodes are package matched with the VSLB3940, TSUS4300, and TSAL4400 IR emitter series. The devices are optimized for data transmission, photo interrupters, optical switches, encoders, and position sensors in metering applications.
