VSHBPW34
Overview
The BPW34 is a high-speed silicon PIN photodiode in a miniature flat plastic package, designed for radiant sensitive applications from 400 nm to 1100 nm. It features a large sensitive area of 7.5 square millimeters while maintaining a low junction capacitance, making it ideal for high-bandwidth light detection and fast optical switching.
Why Choose This Part
The BPW34 offers an excellent balance of high sensitivity and high speed with a typical 20 ns response time. Its flat DIL package provides high packing density and a wide viewing angle of 65 degrees, while the 32V maximum reverse voltage rating allows for versatile circuit design.
Applications
Key Specifications
Getting Started
To achieve maximum speed, operate the BPW34 in photoconductive mode with a reverse bias (up to 32V) to minimize junction capacitance. For low-noise applications, use a transimpedance amplifier (TIA) circuit to convert the small photocurrent into a usable voltage while maintaining bandwidth.
