ONSEMI FDA59N30 N-Channel MOSFET, 300V 59A, TO-3P Package

The ONSEMI FDA59N30 is a 300V N-channel UniFET™ MOSFET engineered for high-performance switching applications. Built on advanced planar stripe and DMOS technology, it is designed to deliver a significantly reduced on-state resistance, superior switching performance, and enhanced avalanche energy strength for greater system robustness.

A key advancement is the improved performance of the integrated body diode. Through lifetime control technology, its reverse recovery time (trr) is under 100ns with a reverse dv/dt immunity of 15V/ns. This is a substantial improvement over standard planar MOSFETs, which typically have trr over 200ns and dv/dt immunity of just 4.5V/ns. This enhancement can eliminate the need for additional external components in many circuits, thereby simplifying design and improving overall system reliability, particularly in applications where the body diode's performance is critical.

The MOSFET features a low gate charge, facilitating faster and more efficient switching, and is subjected to 100% avalanche testing to ensure maximum durability under stressful operating conditions. It is housed in a robust TO-3P through-hole package, offering excellent thermal performance for high-power dissipation.

Ideal Applications

This versatile component is perfectly suited for a wide range of power conversion and management systems, including:
