Sfh 309 Fa 4
Overview
Product sourcing insights & recommendations


The SFH 309 FA-4 is a high-performance Silicon NPN Phototransistor from ams OSRAM, specifically designed for infrared sensing in industrial and automotive applications. It features a peak spectral sensitivity of 900 nm and a focused viewing angle of ±12° (24° total), integrated with a daylight filter to minimize visible light interference Rs-OnlineNewark.
Market Trends & Business Insights (2026)
The market for these components is currently shaped by ams OSRAM's strategic pivot and broader electronic supply chain dynamics:
* Strategic Realignment: As of July 2026, ams OSRAM has completed the sale of its non-optical sensor business to Infineon, focusing instead on "Digital Photonics" pillars: AR Smart Glasses, AI Photonics, and Advanced Sensing (dToF) Deutsche-BoerseInvesting.
* Strong Growth & Demand: The company's semiconductor core portfolio reported a 13% like-for-like growth in Q2 2026, driven by record design wins in automotive and industrial robotics Investing.
* Pricing & Lead Times: While ams OSRAM is seeing robust order entry, the broader electronic component market is facing aggressive price hikes and lead time extensions from major manufacturers like Microchip and Molex, which may impact general availability of discrete components like the SFH 309 series Unikeyic.
