Overview

The Vishay BPW34S is a high-speed PIN photodiode designed for general-purpose applications in visible and near-infrared light detection. Its compact surface-mount package and fast 100ns response time make it suitable for various optical sensing tasks. This variant offers a specific lead form (Gull Wing) for alternative mounting considerations.

Why Choose This Part

Engineers benefit from the BPW34S's high photo and radiant sensitivity, ensuring reliable detection across a wide spectral range from 430nm to 1100nm. The fast response time of 100ns is critical for high-speed applications. Its surface-mount Gull Wing package simplifies automated assembly processes.

Applications

High-Speed Photo Detector
Utilizing its fast response time, the BPW34S can be used in applications requiring rapid detection of light pulses or changes in light intensity.
Optical Switches and Counters
Its sensitivity to visible and near-infrared radiation makes it suitable for integration into optical switches, object detection, and counting systems.
Light Barrier Systems
Can be employed in light barrier setups where a modulated light source and detector pair are used to detect obstructions.
Ambient Light Sensing
Appropriate for applications needing to measure or detect ambient light levels due to its broad spectral range of 430nm to 1100nm.

Getting Started

To get started with the BPW34S, integrate it into a transimpedance amplifier circuit to convert the photodiode's current into a measurable voltage. Consider using an oscilloscope to characterize its response time and linearity with different light sources. Standard PCB layout practices for high-speed analog signals should be followed to minimize noise.

Also Consider

BPW34 VSHVishay - This is the through-hole variant of the same photodiode, suitable for designs where through-hole mounting is preferred.
