Infineon IGLT65R055B2 CoolGaN™ 650V G5 Bi-Directional Switch

Introduction

The Infineon IGLT65R055B2 is a 650 V CoolGaN™ G5 bi-directional switch designed for high-efficiency power-conversion systems. Built using gallium nitride technology, it combines bidirectional voltage-blocking capability with dual-gate control in a compact semiconductor device.

Part Description

The IGLT65R055B2 is part of Infineon Technologies’ CoolGaN™ 650 V G5 Bi-Directional Switches, also known as BDS devices. Unlike conventional single-direction switching devices, this transistor is designed to block voltage in both directions, helping simplify certain power-stage topologies.

Its monolithically integrated substrate-voltage control and dual-gate structure support controlled bidirectional operation. Gallium nitride technology enables fast switching performance and can help designers improve converter efficiency, reduce switching losses, and potentially decrease the size of magnetic and thermal-management components.
