Overview

The SFH 320 FA-Z is a high-linearity NPN silicon phototransistor housed in a compact 2-LCC (P-LCC-2) surface-mount package. Featuring an integrated daylight filter, it is optimized for infrared detection at 980nm while suppressing visible light interference. This component is designed for reliable performance in industrial sensing applications with a wide operating temperature range from -40C to 100C.

Why Choose This Part

This phototransistor offers excellent linearity and a low dark current of 50 nA (max), ensuring high signal integrity in precision circuits. The J-Lead 2-LCC package is compatible with all standard reflow soldering processes, facilitating automated assembly in high-volume production. Its 35V collector-emitter breakdown voltage provides robust headroom for various industrial power rail configurations.

Applications

Industrial Optoelectronic Controls
Used in non-contact switching and positioning systems where IR detection is required.
Infrared Remote Receivers
Ideal for sensing IR signals in environments with significant ambient visible light thanks to its 980nm peak sensitivity.
Light Barriers and Curtains
The 120-degree viewing angle makes it suitable for broad-area detection in safety or counting systems.
Proximity Sensing
Integrated into short-range detection circuits for user interface or object presence sensing.

Getting Started

To integrate the SFH 320 FA-Z, design a standard common-emitter or common-collector circuit with a load resistor sized for your desired response time and sensitivity. Ensure the daylight filter's 750nm to 1120nm range aligns with your IR emitter's output for maximum efficiency. For prototyping, the P-LCC-2 footprint can be hand-soldered or mounted on a standard SMT breakout board.

Also Consider

SFH 320-Z ams OSRAM - Select this version if you require sensitivity to visible light as it lacks the daylight filter found on the FA variant.
