BPW20R

BPW20R Vishay Telefunken Silicon PN Photodiode Description BPW20R is a planar Silicon PN photodiode in a hermetically sealed short TO–5 case, especially designed for high precision linear applications. Due to its extremely high dark resistance, the short circuit photocurrent is linear over seven decades of illumination level. On the other hand, there is a strictly logarithmic correlation between open circuit voltage and illumination over the same range. Equipped with a clear, flat glass window, the spectral responsitivity reaches from blue to near infrared. 94 8482 Features D D D D D D Hermetically sealed TO–5 case Flat glass window Cathode connected to case Wide viewing angle ϕ = ± 50 ° Large radiant sensitive area (A=7.5 mm2) Suitable for visible and near infrared radiation D D D D D D High sensitivity UV enhanced Low dark current High shunt resistance Excellent linearity For photodiode and photovoltaic cell operation Applications Sensor for light measuring techniques in cameras, photometers, color analyzers, exposure meters (e.g. solariums) and other medical and industrial measuring and control applications.
