Overview

The BPW 34 FAS-Z is a high-speed Silicon PIN photodiode with a daylight filter specifically designed for infrared applications. It features a large active area of 7.02mm2 and a 20ns response time, making it ideal for high-speed signal detection in the 730nm to 1100nm spectral range.

Why Choose This Part

This photodiode offers a wide 120-degree viewing angle and a low 2nA typical dark current, ensuring high signal-to-noise ratios. Its surface-mount DIL package with a daylight filter effectively rejects visible light interference, simplifying optical design in IR-focused systems.

Applications

Automotive In-Cabin Sensing
Utilized for driver monitoring and interior light control systems requiring fast infrared response.
Rain and Light Tunnel Sensing
Integrated into vehicle safety systems to automatically trigger wipers or headlamps based on ambient IR levels.
Industrial IR Remote Control
High-speed data reception in industrial optical links and infrared remote control receivers.
Optical Communication
Suitable for short-range optical data transmission due to its 25MHz bandwidth and low dark current.

Getting Started

For evaluation, integrate the photodiode into a transimpedance amplifier (TIA) circuit using a high-speed op-amp to convert the nano-ampere photocurrent into a measurable voltage. Ensure the 32V maximum reverse voltage limit is respected to maintain linear response and minimize junction capacitance for high-speed operation.
