Overview
The FSA515UCX is a high-performance single-pole single-throw (SPST) depletion switch produced by onsemi. This device utilizes depletion technology, allowing it to conduct signals when the supply voltage (VDD) is low and isolate signals when VDD is high. It is designed to handle negative signal swings down to -3.0 V and is tolerant up to 5.5 V. The FSA515UCX is packaged in a WLCSP4 (Wafer Level Chip Scale Package) and is lead-free, making it suitable for a variety of modern electronic applications.
