最高27%
较竞品1200V器件的比导通电阻（RSP）降幅，在相同5×5mm封装内 比导通电阻降低27%对采购方意味着什么 Gen 5的核心卖点在于较竞品1200V器件将RSP（比导通电阻＝单位芯片面积的导通电阻）最高降低27%。RSP降低意味着可用更小的芯片面积实现相同的导通电阻，从而降低裸片成本并缩小模块尺寸。Wolfspeed称，即便在175°C高温工作下，也能在5×5mm封装内实现最大电流密度，有助于牵引逆变器的小型化与EV电池容量的合理设计。在EV功率模块采购中，Gen 5或将成为竞品比较的新基准。
覆盖1200V与750V的双电压等级部署 Gen 5技术覆盖1200V与750V两个电压等级，同时面向车载牵引逆变器与工业电源。750V等级意在抢占工业逆变器、大功率EV充电基础设施等非车载应用，并适用于以固态断路器替代机械继电器的新用途。各厂商按电压等级完善产品线的趋势正在加速，设计者越来越多地在电压等级与损耗特性两个维度上选型。
見るポイント 200mm量产就绪——供应侧的差异化 Gen 5据称已在Wolfspeed经认证、可量产爬坡、高度自动化的200mm（8英寸）制造平台上实现量产就绪。从样品到量产的过渡是采购方最大的风险因素之一；若200mm产线迁移已完成，则量产出货的路径相对低风险。在部分竞争对手仍以150mm（6英寸）产品线为主之际，这可成为实际供应能力上的差异化点。
需要说明的是，为EV充电基础设施"设定新效率基准"的定位是公司自身的主张，开关性能提升带来的安装成本降低效果，仍以在实际工况下的验证为前提。
给设计与采购人员的要点 Wolfspeed首席商务官Cengiz Balkas表示，Gen 5在Gen 4实现开关突破后不到两年即推出。不到两年的代次更新周期，促使OEM与Tier 1重新审视design-in的时间管理与长期采购合同的更新周期。同时，Wolfspeed正处于财务重整之中，长期供应的确定性应与供应风险评估 一并判断。性能数值为标称值，实际效果取决于栅极驱动设计、开关频率与温度条件，建议在评估板上通过双脉冲测试确认实机特性。

Wolfspeed unveils Gen 5 SiC MOSFET, cutting specific on-resistance by up to 27% vs. competing 1200V products
On June 9, 2026, Wolfspeed announced its fifth-generation SiC MOSFET technology. It reduces specific on-resistance (RSP) by up to 27% versus commercially available competing 1200V solutions, achieving an industry-low level. It delivers maximum current density in a 5×5mm footprint even at 175°C operation. The generational update comes less than about two years after Gen 4.
Wolfspeed Gen 5 covers 1200V and 750V for automotive and industrial use
Gen 5 technology covers both the 1200V and 750V voltage classes, addressing automotive traction inverters and industrial power supplies. It is designed to deliver maximum current versus competing products in a 5×5mm SiC footprint. It is also said to be applicable to new use cases that replace mechanical relays with solid-state circuit breakers.
Wolfspeed's Gen 5 is production-ready on a 200mm SiC wafer manufacturing platform
Gen 5 technology is based on Wolfspeed's qualified, production-ramp-ready, highly automated 200mm manufacturing platform. The company says this gives automotive and industrial customers a fast, low-risk path to market. The transition to the 200mm platform is already complete, leaving a low barrier to volume shipments.
Gen 5 sets a new efficiency benchmark for EV charging infrastructure, accelerating SiC adoption in that market
Wolfspeed says Gen 5 technology sets a new efficiency benchmark for EV charging infrastructure. Improved switching performance is expected to reduce power loss and installation cost on the charger side. The technology covers a broad range of applications beyond traction inverters, including industrial power supplies.
Wolfspeed brought Gen 5 to market less than two years after Gen 4, accelerating its innovation pace
Wolfspeed CBO Cengiz Balkas said the company delivered Gen 5 less than two years after achieving a switching breakthrough with Gen 4. Gen 5 is said to enable the maximum current an engineer can achieve in the same 5×5mm footprint. This innovation pace signals a technology-roadmap advantage over competitors.
