VISHAY BPW85 NPN Phototransistor, T1 Case
VISHAY BPW85 silicon NPN phototransistor with high sensitivity & fast response for visible/NIR sensing. T-1 3mm case, 50° viewing angle.
The VISHAY BPW85 is a clear silicon NPN phototransistor designed for high radiant sensitivity in the visible and near-infrared spectrum. This component offers exceptionally fast response times, making it an ideal choice for applications where rapid detection of light changes is critical. Its high photo and radiant sensitivity ensures reliable performance even in low-light conditions, providing accurate and stable signal output.
Encased in a standard T-1 (3mm) package, the BPW85 features a viewing angle of 50° and an angle of half sensitivity of ±25°, allowing for effective light capture from a broad field. With a typical peak sensitivity wavelength of 850nm, it is perfectly suited for infrared sensing systems. The device has a low power consumption of 100mW and is supplied with two pins for easy integration into a wide range of electronic circuits.
