I. Nexperia GaN Bi-Directional Switch

The Nexperia GaN bidirectional switch is an innovative power device specifically developed for bidirectional current control and bidirectional voltage blocking applications. It revolutionises the traditional bidirectional circuit design—which involves ‘two silicon MOSFETs connected back-to-back in series’—by leveraging the inherent properties of GaN to achieve native bidirectional conduction and voltage withstand capabilities. This significantly simplifies system architecture, reduces component costs and PCB footprint, making it a core upgrade component for battery management, load switching, and circuit protection.

1. Core Technologies and Product Advantages

Compared to traditional silicon-based bidirectional circuit solutions, Nexperia’s GaN bidirectional switches offer comprehensive performance advantages. Firstly, the devices possess native bidirectional electrical characteristics, enabling bidirectional current conduction and voltage blocking without the need for matched MOSFETs. This completely eliminates the issues of device matching errors and the accumulation of parasitic parameters associated with traditional series configurations, thereby significantly enhancing circuit stability. Secondly, leveraging GaN’s high electron mobility, the devices feature extremely low on-resistance (Rds(on)) and ultra-low conduction losses, effectively reducing operating temperature rise and alleviating system thermal management demands.

Furthermore, this series of switches offers ultra-fast switching response times, with losses far lower than those of silicon-based devices under high-frequency operating conditions. This supports high-frequency power conversion designs, helping to enhance power density and reduce the overall size of equipment. The devices feature extremely high integration, with a single chip replacing a dual-MOSFET architecture, directly reducing the number of components, simplifying PCB layout, and lowering production and assembly costs as well as the probability of circuit failure. Furthermore, the products offer excellent thermal stability and immunity to interference, with a wide operating temperature range, making them suitable for demanding industrial and automotive applications, whilst meeting RoHS, lead-free and REACH environmental compliance requirements.

2. Key Product Models and Specification Features

Nexperia has prioritised the development of low-voltage GaN bidirectional switch products, with the flagship model GANB4R8-040CBA serving as a benchmark device for compact, high-performance applications. This device features a 40V voltage rating, a typical on-resistance of just 4.8 mΩ and extremely low on-resistance losses; utilising an enhancement-mode normally-off design with a default off-state, it offers enhanced circuit safety and is suitable for a wide range of controlled switching applications. The device is housed in a 2.1 mm × 2.1 mm wafer-level chip-scale package (WLCSP), which minimises the space required and makes it ideally suited for space-constrained applications such as portable consumer electronics and small-scale energy storage devices.

3. Key Application Scenarios

Nexperia’s GaN bidirectional switches are precisely tailored for a wide range of bidirectional power control scenarios, with core applications spanning three major areas. Firstly, Battery Management Systems (BMS), used for bidirectional control of lithium-ion battery charging and discharging, as well as reverse connection protection; these replace traditional dual-MOSFET protection circuits, simplifying the design whilst enhancing protection response speed. Secondly, smart load switches, used for bidirectional on/off control in portable devices, smart home applications and small industrial loads, enabling low-loss power switching. Thirdly, circuit reverse protection and current limiting applications, suitable for low-voltage energy storage modules, wearable devices and automotive low-voltage circuits, delivering efficient and stable circuit protection and power regulation.

II. Nexperia GaN Field-Effect Transistors (GaN FETs)

Nexperia GaN field-effect transistors are universal bidirectional power switching devices built on GaN HEMT technology. They are categorised into two major technical architectures: Enhancement-mode (E-mode) and Common-Source Cascode (Cascode), covering the full voltage range from low voltage (<80V), medium voltage (80–200V), high-voltage (650 V) ranges. They are fully compatible with a wide range of high- and low-power applications, including consumer electronics, industrial power supplies, server computing, renewable energy photovoltaics and telecommunications power supplies, and are the key components for replacing traditional silicon MOSFETs and enhancing power supply efficiency and power density.

1. Core Technical Architecture and Advantages

Nexperia’s GaN FETs combine proprietary high-voltage GaN HEMT technology with mature low-voltage silicon MOSFET processes, delivering both high performance and high reliability. The entire product range employs a normally-off enhancement-mode design, eliminating the risk of leakage current in the on-state. This ensures simple circuit control and high safety, whilst remaining compatible with traditional silicon MOSFET drive logic, allowing for seamless replacement and upgrades without the need for significant circuit modifications.

The devices feature extremely low dynamic and reverse conduction losses, with industry-leading soft-switching performance. They effectively reduce switching losses under high-frequency operating conditions, enabling power conversion efficiency of up to 99 per cent or higher. Furthermore, they offer a wide gate drive voltage range (0–12 V), enabling simple and versatile drive designs that are compatible with mainstream power supply driver ICs, thereby reducing R&D and debugging costs. The product range is available in a variety of package types, including mainstream options such as DFN, TO-247, TOLL and CCPAK, catering to the needs of both compact consumer applications and high-power industrial applications. Furthermore, with extremely low parasitic parameters, faster switching speeds and reduced electromagnetic interference, these devices facilitate high-frequency, compact designs.
