BPW97
Vishay Telefunken
Silicon PIN Photodiode
Description
BPW97 is an extra high speed PIN photodiode in a hermetically sealed TO–18 package. Unlike most similar devices, the cathode terminal is isolated from case and connected to a third terminal, giving the user all the means to improve shielding of his system. Due to its high precision flat glass window and its accurate chip alignment, this device is recommended for ambitious applications in the optical data transmission domain.
Features
D Extra fast response times at low operating voltages

Exact central chip alignment Chip insulated Shielded construction Hermetically sealed TO–18 case Flat optical window Wide angle of half sensitivity ϕ = ± 55° Radiant sensitive area A=0.25mm2 Suitable for visible and near infrared radiation Suitable for coupling with 50 mm gradient index fiber
Applications
Wide band detector for demodulation of fast signals, e.g. of lasers and GaAs emitters. Detector for optical communication, e.g. for optical fiber transmission systems with only 5 V power supply.

Vishay Telefunken Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to 1. Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances ( ODSs ). The Montreal Protocol ( 1987 ) and its London Amendments ( 1990 ) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively 2 . Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency ( EPA ) in the USA 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C ( transitional substances ) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances.
We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay-Telefunken products for any unintended or unauthorized application, the buyer shall indemnify Vishay-Telefunken against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
