EL SEGUNDO, Calif. — February 2025 — EPC, the leader in gallium nitride (GaN) power devices, announces the release of its
Phase 17 Reliability Report, further solidifying GaN’s position as a highly
reliable technology for power electronics, automotive, AI, space, and industrial applications.
The latest reliability report introduces expanded lifetime models, mission-specific reliability projections, and new physics-based wear-out mechanisms, providing
engineers with more accurate and practical reliability data for GaN power devices.
Key Highlights of the Phase 17 Reliability Report
- Expanded Gate Lifetime Model: Incorporates gate leakage current effects across voltages and temperatures, leading to enhanced impact ionization modeling
- Repetitive Transient Gate Overvoltage Testing: Develops and validates a 7 V gate overvoltage rating, addressing resonance-like transient stress in real-world applications
- Enhanced Drain Overvoltage Robustness: Further validation of GaN’s superior durability under repetitive transient drain-source overvoltage conditions
- New Pulsed Current Rating Data: Extends testing to over 100 million pulses, proving minimal parametric shifts in Gen-5 and Gen-6 GaN devices
- Comprehensive Thermomechanical Lifetime Model: Now includes power cycling (PC) modeling, essential for high-stress applications like automotive and AI power systems
- Mission-Specific Reliability Insights: Expanded analysis for solar, lidar, and DC-DC conversion applications, allowing engineers to fine-tune their designs for long-term operation
Driving GaN Forward in Reliability & Performance
EPC’s test-to-fail methodology continues to push GaN technology beyond traditional silicon MOSFETs. By integrating real-world stress conditions into advanced lifetime models,
the Phase 17 report ensures more accurate reliability projections for next-generation power applications.
This report advances GaN reliability modeling with mission-specific projections and new lifetime models, enabling engineers to integrate GaN into high-power, efficient, and robust designs with confidence,
said Alex Lidow, EPC CEO and co-founder.
