STMicroelectronics SGT3D5R10MEB PowerGaN Transistor

Introduction

The STMicroelectronics SGT3D5R10MEB is a high-performance enhancement-mode gallium nitride (GaN) power transistor designed for fast, efficient switching in demanding power-conversion systems. Its 100 V drain-source rating, very low on-resistance, and high current capability make it suitable for compact designs where conduction and switching losses must be minimized.

Part Description

The SGT3D5R10MEB is an N-channel, enhancement-mode PowerGaN FET in an FCLGA-8 surface-mount package. It supports up to 100 V operation and is specified for continuous drain currents up to 201 A.

With a milliohm-range on-resistance—listed as 2.9 mΩ typical in the product title and 3.5 mΩ in the product description—the device is intended to reduce conduction losses in high-current switching paths. As a GaN-based transistor, it is suited to high-frequency switching designs that benefit from improved efficiency, smaller magnetic components, and reduced system size compared with many conventional silicon-based alternatives.
