Overview

The BPW41N is a high-speed silicon PIN photodiode specifically designed for infrared radiation detection in a side-view radial package. It features an integrated daylight blocking filter that is spectrally matched with 940nm IR emitters, providing high radiant sensitivity while minimizing interference from visible light.

Why Choose This Part

The component offers a wide viewing angle of 130 degrees and a large 7.5mm active area for high sensitivity. Its low dark current of 2nA and high reverse voltage rating of 60V allow for precise detection and robust circuit design in varied lighting conditions.

Applications

Infrared Remote Controls
Ideal for consumer electronic receivers and home automation control systems using 940nm modulation.
High-Speed Data Transmission
Supports free-air optical data links requiring fast response times and bandwidth up to 4MHz.
Industrial IR Barriers
Used in light curtains and proximity sensing where side-looker orientation is required for PCB mounting.
Optical Switching
Reliable detection for optical interrupters and encoders in noisy ambient light environments.
