WeEn Semiconductors, a leader in advanced bipolar power semiconductor solutions, today announced the launch of its 2000V High-Voltage (HV) series of standard rectifiers. Designed to address the evolving demands of high-voltage systems, these rectifiers achieve a 5% reduction in forward voltage drop (VF) and a 20% improvement in thermal resistance compared to competing solutions. The innovations enable significant efficiency gains, lower cooling costs and extended operational lifespans in renewable energy storage and electric vehicle (EV) fast-charging applications.
Key Features and Benefits
The 2000V HV series integrates a proprietary single-chip design to minimize conduction losses with an optimized ORing circuit that enhances thermal management. This combination ensures reliable performance in 1500V bus systems and 1000VDC EV charging infrastructure, where voltage spikes and stray inductance pose risks to component longevity. Additional advantages include:
- High Junction Temperature (Tjmax): Operates up to 150°C, ensuring stability in demanding environments.
- Superior Surge Current (IFSM) Tolerance: Enhances robustness under dynamic load conditions.
- TO247-2L Packaging: Streamlines integration into high-power designs.
Two initial variants are available: the 60A-rated WND60P20W and the 90A-rated WND90P20W. These devices are engineered to mitigate voltage spikes in fast-changing EV charging loads, safeguarding systems against failure while improving power density.
Leadership Insight
“The WND90P20W and WND60P20W resolve critical thermal and efficiency challenges in next-gen renewable energy and EV charging systems,” said Kevin Shen, President of WeEn Semiconductors. “By redefining voltage redundancy and thermal performance, we empower customers to deploy high-efficiency, low-maintenance solutions that outpace industry standards.”
Availability and Applications
The 2000V HV rectifiers are now available globally in TO247-2L packages. Target applications include solar PV inverter and storage systems, DC fast EV chargers, and industrial power systems requiring high voltage endurance and reliability.
