3-mm lens high-speed PIN photodiodes in clear- and black-epoxy T1 plastic

Vishay Intertechnology has extended its optoelectronics portfolio with the introduction of high-speed silicon PIN photodiodes with high radiant sensitivity and fast switching times in clear- and black-epoxy T1 plastic packages. Offering 3 mm lenses, the TEFD4300 and TEFD4300F feature a high reverse photo current of 17 A 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 350 nm to 1120 nm. For light sources in the infrared wavelength range of 770 nm to 1070 nm, the TEFD4300F is a black epoxy device with a daylight blocking filter matched with 850 nm to 950 nm IR emitters. The photodiodes offer fast switching times down to 10 ns 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 950 nm wavelength of peak sensitivity.

The devices are package matched with the VSLB3940, TSUS4300, and TSAL4400 IR emitter series. The photo detectors support lead (Pb)-free processing in accordance with RoHS 2002/95/EC and WEEE 2002/96/EC, and conform to Vishay "Green" environmental specifications.
