Overview

The VBPW34SR is a high-speed silicon PIN photodiode designed for radiant-sensitive applications in both the visible and near-infrared spectrum. It features a large 7.5mm2 active area and a wide 130-degree viewing angle, making it ideal for detecting radiation from 430nm to 1100nm. The surface-mount package with reverse gullwing (Z-bend) leads allows for compact integration into high-speed optical detection systems.

Why Choose This Part

The component offers a low dark current of 2nA and a high reverse breakdown voltage of 60V, ensuring low noise and stability in various biasing conditions. Its wide spectral range from 430nm to 1100nm provides versatility for detecting both ambient light and dedicated infrared emitters.

Applications

High Speed Photo Detection
Utilizing its 100ns response time for fast pulse detection in optical communication or synchronization systems.
Infrared Remote Control
Acting as a receiver for 940nm infrared signals in consumer electronics and industrial control interfaces.
Light Barriers and Safety Curtains
Used in industrial sensing to detect the presence or absence of light beams across wide angles.
Optical Switching
Providing reliable state switching in automated process control where high radiant sensitivity is required.

Getting Started

To integrate the VBPW34SR, design a transimpedance amplifier (TIA) circuit to convert the photodiode's current output into a usable voltage signal. Ensure proper PCB layout to minimize parasitic capacitance around the high-impedance nodes for maximum bandwidth, and follow lead-free reflow soldering profiles during assembly.
