Why GaN for Power Conversion Applications?
GaN possesses many properties that make it an ideal material for power conversion devices. Its performance is substantially superior to silicon, and it is more cost effective than other compound power semiconductors such as silicon carbide.
- Wider Band Gap Reduces On-Resistance at High Voltage
- Higher Electron Mobility Enables Faster Switching
- High Temperature Capability for Improved Reliability
- Lower Cost — Can Be Grown on Silicon Substrates
GaN-based power devices can achieve a specific on-resistance that is 100 times lower than silicon super junction transistors and even 10 times lower than SiC transistors. This enables much smaller die size, lower output capacitance, higher efficiency, and faster switching — ultimately leading to major system cost savings and smaller board footprints.
rGaN-HV — a State-of-the-Art Process Technology
RFMD’s high-voltage GaN, rGaN-HV, encompasses a family of normally-off power switches to provide the first practical 600V GaN solution utilizing a HEMT (high electron mobility transistor) structure. The RFMD Source Switched FETs (SSFETs), housed in standard TO247 packages, will provide immediate efficiency improvements as a drop-in replacement for super junction transistors or IGBTs in a broad range of applications.
RFMD today announced the extension of its industry-leading GaN process
technology portfolio to include a new technology optimized for high voltage
power devices in power conversion applications. RFMD's rGaN-HV enables
substantial system cost and energy savings in power conversion applications
ranging from 1 to 50 KW. rGaN-HV delivers device breakdown voltages up to 900
volts, high peak current capability, and ultra-fast switching times for GaN
power switches and diodes.
