I. Infineon CoolGaN™ Bidirectional Switch (BDS)

Infineon’s CoolGaN™ Bidirectional Switch is the industry’s first single-chip, integrated, enhancement-mode GaN device capable of bidirectional conduction and blocking. It completely revolutionises the complex ‘four-transistor parallel’ architecture used in traditional solutions to achieve bidirectional switching functionality. By replacing multiple discrete MOSFETs with a single device, it significantly simplifies circuit design, reduces bill of materials costs and minimises PCB footprint, making it a benchmark product for bidirectional power transfer applications.

1. Core Technologies and Features

This series of devices is based on Infineon’s proprietary Gate-Injected Transistor (GIT) robust architecture and employs a dual-gate independent control design, enabling bidirectional voltage blocking and controllable bidirectional current conduction, whilst offering exceptional adaptability to a wide range of operating conditions. The devices are divided into two main categories: high-voltage industrial-grade and low-voltage general-purpose. The high-voltage variants feature a 650 V voltage rating and ultra-high surge resistance of 850 Vss, making them suitable for harsh industrial electrical environments; the low-voltage 40 V series, meanwhile, is tailored for consumer and automotive lightweight applications. The devices as a whole offer the triple advantage of extremely low on-resistance, low gate charge and low output charge, significantly reducing switching losses and delivering high-frequency performance that far exceeds that of traditional silicon-based devices. They are also certified to JEDEC standards, with their consistency and reliability rigorously verified.

2. Representative Models and Packages

Key models include the industrial high-voltage variant IGLT65R055B2, which utilises a TOLT (Top-Out-of-Line-Thermal) package for excellent heat dissipation efficiency, capable of supporting ultra-high power density operating conditions; and the low-voltage general-purpose variant IGK080B041S, which employs a chip-scale package with top-layer protection, offering a highly compact form factor suitable for miniaturised device designs.

3. Key Application Scenarios

Widely used in bidirectional charging points, battery energy storage systems, bidirectional DC-DC converters, solid-state circuit breakers, motor forward/reverse control, and new energy vehicle power conversion equipment, these devices are perfectly suited to power electronic systems requiring bidirectional power flow, simplified topologies and high reliability.

II. Infineon CoolGaN™ Smart Devices

Infineon’s GaN smart devices are integrated smart power products upgraded from basic GaN power chips. They break away from the traditional ‘power chip plus peripheral protection circuit’ combination found in discrete devices, integrating power switches, detection circuits, protection modules and logic control units onto a single chip. This enables intelligent, self-healing operation of power devices, significantly reducing system commissioning complexity and enhancing operational stability.

1. Core Technologies and Features

This series of devices utilises the mature CoolGaN™ G5-generation GaN process as its core substrate. They incorporate a comprehensive suite of intelligent protection functions, including overcurrent protection, overtemperature protection, overvoltage protection and gate anti-mis-triggering. These features enable real-time monitoring of device operating conditions and rapid self-locking protection in the event of anomalies, thereby preventing device burnout and system failures. Compared to discrete solutions, these smart GaN devices eliminate the need for complex external protection circuits, significantly streamlining the bill of materials (BOM) and shortening the R&D cycle. They also support high-frequency switching operation, combining low loss, high immunity to interference and high stability, making them suitable for demanding industrial environments.

2. Key Product Advantages

Firstly, high integration: a single device integrates power, drive, protection and monitoring functions, enabling ‘plug-and-play’ operation; secondly, high reliability: built-in hardware-level rapid protection with a response speed far exceeding that of external protection circuits, preventing damage to the device caused by transient electrical surges; thirdly, ease of design: no complex parameter matching is required, lowering the design threshold for engineers and meeting mass production requirements; fourthly, high adaptability: it is compatible with mainstream high-frequency topologies and can be flexibly adapted to equipment of different power ratings.

3. Core Application Scenarios

Primarily targeted at industrial switching power supplies, high-power fast-charging adapters, server power supplies, PV micro-inverters, small industrial frequency converters, and high-power smart home power supply equipment—scenarios that demand extremely high levels of stability, integration and mass production efficiency.

III. Infineon CoolGaN™ Transistors (GaN HEMT)

Infineon’s CoolGaN™ transistors are enhancement-mode (normally-off) GaN high-electron-mobility transistors. As the foundational core components of the entire GaN product portfolio, they are based on a mature GIT process architecture and combine extremely low losses, ultra-high switching speeds and long-term operational stability. They serve as the core components for high-frequency, high-efficiency power conversion systems, covering the full range of voltage levels from low to high voltage.

1. Core Technologies and Characteristics

The devices utilise a gold-free, reliable enhancement-mode structure with a normally-off state, enabling simple drive logic and enhanced safety whilst avoiding the power-up risks associated with depletion-mode devices. Compared to traditional silicon MOSFETs, CoolGaN™ transistors offer three key advantages: zero reverse recovery charge, extremely low gate charge and extremely low on-state loss. They can achieve switching frequencies exceeding the MHz range, significantly enhancing system power density and reducing the size of passive components such as transformers and capacitors. Furthermore, the devices feature strong surge immunity, minimal switching jitter and excellent stability under high-frequency operating conditions, supporting continuous full-load operation.

2. Product Categories and Features

By voltage rating, the products are divided into three main series: the 40V low-voltage series is suitable for automotive and consumer electronics applications; the 200V medium-voltage series is suitable for small-to-medium-power industrial power supplies; and the 600V/650V high-voltage series is designed for high-power industrial and new energy applications. The entire range supports top-side cooling packaging, which features a short heat dissipation path and low thermal resistance, enabling high-power-density integration and suitability for compact equipment designs.
