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
● 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 μm 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.
