New series of high-speed PIN photodiodes from Vishay

Vishay has introduced the VBPW34x and VBP104x, a series of eight high-speed SMD PIN photodiodes, which are optimized for smoke detection, detectors in light barriers, and data transmission in a wide range of consumer and industrial applications.

The VBPW34FAS, VBPW34FASR, VBP104FAS, and VBP104FASR photodiodes feature a daylight-blocking filter matched with IR emitters operating at a wavelength of 870 nm or 950 nm, such as Vishay's TSFFxxxx series. These devices are optimized to detect infrared signals in light barrier applications covering the range of 780 nm to 1050 nm, and offer a peak wavelength of 950 nm.

For high-speed photo detection, the VBPW34S, VBPW34SR, VBP104S, and VBP104SR clear epoxy devices are ideal for signal detection in the spectral range of 430 nm to 1100 nm, and offer a peak wavelength of 940 nm.

The VBPW34x series photodiodes feature a large optical sensitive area of 7.5 mm2 that provides a high output signal of 55 µA typical at an illumination condition of 1 mW/cm2 at 950 nm and 5-V reverse bias. The VBP104x series devices offer a small optical sensitive area of 4.4 mm2 that provides an output signal of 35 µA and 30 % low capacitance.
