Additional Details

The BSL314PE operates with a low gate-source voltage threshold, making it ideal for direct interfacing with microcontrollers and other logic devices. The drain-source voltage rating and continuous drain current will vary depending on the specific package and variant. Always consult the Infineon datasheet for detailed specifications, including maximum voltage and current ratings, on-resistance characteristics, and thermal performance. This MOSFET is typically RoHS compliant. Care should be taken to manage heat dissipation, particularly at higher currents. As an end-of-life component, sourcing may require contacting specialized distributors or exploring alternative replacement parts.
