Preferred Power Solution: Wayon VDMOS Offers High Versatility and Durability
VDMOSFET, fully named Vertical Double-diffused Metal Oxide Semiconductor Field Effect Transistor, features high input impedance, fast switching speed, and good thermal stability. It also has a positive temperature coefficient and excellent current self-regulation ability.
Advantages and Features of WAYON VDMOS Products
In VDMOSFET design, Wayon focuses on optimizing the contradiction between breakdown voltage and on-resistance, enhancing breakdown voltage while maintaining low on-resistance, and reducing Qg and switching losses. Wayon VDMOSFET improves avalanche tolerance through optimized design, broadens the safe operating area, and thus enhances versatility and durability. For high-reliability applications such as industrial control, Wayon developed a high-quality silicon nitride passivation layer process that significantly improves device reliability.
