BSR14 – FSC

Overview

The onsemi BSR14 is a high-performance NPN bipolar junction transistor (BJT) designed for general-purpose amplification and switching applications. Its critical operational characteristic lies in its 800 mA continuous collector current capability, enabling it to handle moderate power loads. A key design consideration for engineers utilizing the BSR14 is managing its 350 mW power dissipation within the compact SOT-23-3 package; exceeding this limit necessitates thermal management strategies like PCB copper pour or heatsinking to prevent premature device failure and maintain performance integrity, especially in high-ambient temperature environments.
