Driven by the dual forces of automotive electrification and supply chain autonomy, the domestic substitution of core power devices has evolved from a backup option to a strategic imperative. Facing the stringent requirements for high reliability and stability in various applications, finding a domestic alternative solution that is reliable in quality and stable in supply has become a critical task for numerous manufacturers. When focusing on the classic 800V N-channel MOSFET from ROHM—the R8002ANJFRGTL—the VBL185R02, launched by VBsemi, emerges as a formidable contender. It not only achieves precise performance alignment but also offers enhanced voltage rating and robust characteristics, representing a value transformation from "usable" to "reliable," from "substitution" to "secure."
I. Parameter Comparison and Performance Strengths: Advantages Brought by Planar Technology
The R8002ANJFRGTL has earned recognition in applications like power supplies and industrial controls due to its 800V voltage rating, 2A continuous drain current, and 4.3Ω on-state resistance.
