GaN Outperforms Silicon: Market Poised for Massive Expansion

 

The global Power Gallium Nitride (GaN) devices market is on a steep growth trajectory. Valued at US$ 84.4 million in 2021, the industry is projected to expand at an astonishing CAGR of 40.6% from 2022 to 2031, reaching US$ 2.5 billion by the end of the forecast period. This pace reflects GaN’s unique position as the semiconductor material set to redefine power electronics across industries—from consumer gadgets to electric vehicles and 5G infrastructure.

 

Why GaN is Disrupting Power Electronics

Gallium Nitride is a wide-bandgap semiconductor with a 3.4 eV bandgap, significantly higher than silicon’s 1.12 eV. This translates into higher breakdown voltages, faster switching speeds, and improved energy efficiency.

Compared to silicon-based devices, GaN devices offer:

• Up to 99% power conversion efficiency (vs. ~95% for silicon solutions in industrial power supplies)
• Smaller size and lighter weight for circuit integration
• Superior thermal management
• Higher switching frequency and reduced component count

The result? Compact, energy-efficient solutions that open up new design possibilities in chargers, power converters, amplifiers, and beyond.

 

Key Growth Drivers

1. Consumer Electronics: From Phones to Power Tools

GaN-based chargers are rapidly replacing traditional silicon in smartphones, laptops, and portable electronics. OEMs are responding to demand for smaller, faster-charging adapters—often capable of powering multiple devices simultaneously.

For example, in August 2022, Navitas Semiconductor announced that its GaN power IC technology was integrated into OnePlus’s 160W in-box charger for the OnePlus 10R 5G and OnePlus ACE 5G smartphones.

Beyond chargers, GaN’s high-speed switching and compact footprint are enhancing AI devices, biometrics, and voice recognition systems.

 

2. Industrial Power Supplies

In industrial settings, GaN technology enables higher efficiency, power density, and bidirectional power flow, all while reducing heat loss. With efficiencies of up to 99%, GaN converters significantly lower operational costs over time.

Applications range from factory automation to renewable energy systems, where efficiency and compact form factors are critical.

 

3. Data Centers & 5G Infrastructure

Data center demand is surging, fueled by 15–30 million connected devices worldwide and projected annual expansion of ~10%. This has elevated the importance of energy efficiency in computing and storage.

GaN is steadily replacing silicon in server power supplies, UPS systems, and telecom switching racks, enabling:

• Higher computing power per rack footprint
• Reduced cooling requirements
• Smaller, lighter infrastructure

In 5G networks, GaN boosts power density in RF radios, MIMO systems, antenna modules, and BTS equipment. It enables operators to deploy lighter, more efficient base stations, reducing rollout costs.

China, for example, is set to invest over US$ 170 billion in 5G infrastructure by 2025, representing a major demand driver for GaN-based RF and power devices.

 

4. Electric Vehicles (EVs) and Inverters

Automotive applications, particularly in EV/HEV inverters, remain a frontier for GaN adoption. While silicon carbide (SiC) has dominated high-voltage drivetrain applications, GaN’s efficiency and compactness are drawing attention for on-board chargers, DC-DC converters, and auxiliary systems.

Industry players are actively researching GaN solutions that can handle high-voltage, high-current demands in harsh automotive environments.
