Osram BPW21 Silicon Photodiode

A silicon photodiode especially suited for applications from 350nm to 820nm. Adapted to human eye sensitivity, hermetically sealed metal package, exposure meter for daylight, artificial light of high colour temperature in photographic fields and colour analysis.

• Especially suitable in the 350 to 820nm wavelength range
• Hermetically sealed two pin package, similar to TO-5
• Low dark current
• Fast rise and fall time
• Case is cathode, insulated pin is anode
