ROHM Semiconductor 600V Super Junction MOSFETs

Introduction

ROHM Semiconductor R60xxXNx and R60xxWNx 600V Super Junction MOSFETs are power transistors designed for efficient, compact, and high-power-density switching applications. These devices support modern power-conversion designs where low power loss, fast switching behavior, and effective thermal performance are essential.

Part Description

The R60xxXNx / R60xxWNx family consists of 600V Super Junction (SJ) MOSFETs from ROHM Semiconductor. Super Junction MOSFET technology helps reduce on-resistance while maintaining a high voltage rating, improving efficiency in switching power circuits.

The R60xxXNx series is intended for high-speed switching applications, making it suitable for converters and power stages operating at elevated switching frequencies. The PrestoMOS™ R60xxWNx series emphasizes high-speed recovery characteristics, helping reduce switching losses and improve overall converter performance.

These MOSFETs are available in DFN8080-5L surface-mount and TOLL package options. Both package styles support compact layouts and strong heat dissipation, allowing designers to build smaller power supplies and densely integrated power systems.
