50V N-Channel MOSFET AF15N50

Data Sheet

General Description

This N-Channel MOSFET has been designed specifically to improve the overall efficiency and to minimize switch node ringing of DC-DC converters using either synchronous or conventional switching PWM controllers. It has been optimized for low gate charge, low R diode reverse recovery performance.

The AF15N50 is available in PDFN-5×6-8 package.
