BPW-34 series are a family of high quality and reliability plastic encapsulated
photodiodes. All three types of devices in this series, exhibit similar electrical
characteristics, but vary in optical response. BPW-34B has an excellent re-
sponse in the blue region of the spectrum, while BPW-34F is an excellent
choice for applications requiring blocking the visible light. They are excellent
for mounting on PCB and hand held devices in harsh environments.
• IR Sensors • High Reliability
• Bar Code Scanners • High Density Package
• Color Analysis • Rugged Resin Mold
• Smoke Detectors • Fast and Low Dark Current
