Description
BPW34 High-Speed PIN Photodiode Sensor for Visible & Infrared Light Detection
The BPW34 PIN Photodiode is a high-speed, high-sensitivity silicon photodiode designed for precise detection of visible and near-infrared (NIR) light. Housed in a compact DIP-2 package, it offers excellent linearity, low dark current, and fast response time, making it ideal for optical sensing, light measurement, IR communication, and scientific instrumentation.
With a peak sensitivity at 900nm and a spectral response ranging from 430nm to 1100nm, the BPW34 is suitable for applications involving infrared emitters, optical switches, laser detection, ambient light sensing, and optical encoders. Its ±65° reception angle provides a wide field of view, while the low 2nA dark current ensures accurate light detection with minimal noise.
Manufactured by Semiconductors, the BPW34 is widely used in industrial automation, educational projects, robotics, medical devices, and embedded systems where reliable optical sensing is essential.
Note: Refer to the official datasheet for detailed electrical characteristics and application circuits.
