IRFU014 N-Channel MOSFET Equivalent & Substitute Parts

Part Overview

The IRFU014 is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 60V drain-to-source voltage with a continuous drain current of 7.7A at 25°C. The device is housed in a TO-251AA through-hole package and is designed for general-purpose switching applications requiring moderate power dissipation.

The IRFU014 carries an obsolete product status, making it necessary to identify equivalent substitute parts for new designs and ongoing production requirements. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.
