基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET兩大主要特色:
 
1.出類拔萃的可靠性:相對(duì)競(jìng)品較為充足的設(shè)計(jì)余量來(lái)確保大規(guī)模制造時(shí)的器件可靠性。
基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET 1200V系列擊穿電壓BV值實(shí)測(cè)在1700V左右,高于市面主流競(jìng)品,擊穿電壓BV設(shè)計(jì)余量可以抵御碳化硅襯底外延材料及晶圓流片制程的擺動(dòng),能夠確保大批量制造時(shí)的器件可靠性,這是基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET布袋除塵器關(guān)鍵的品質(zhì). 基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET雪崩耐量裕量相對(duì)較高,也增強(qiáng)了在電力電子系統(tǒng)應(yīng)用中的可靠性。
 
2.可圈可點(diǎn)的器件性能:同規(guī)格較小的Crss帶來(lái)出色的開(kāi)關(guān)性能。
基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET反向傳輸電容Crss 在市面主流競(jìng)品中是比較小的,帶來(lái)關(guān)斷損耗Eoff也是市面主流產(chǎn)品中非常出色的,優(yōu)于部分海外競(jìng)品,特別適用于LLC應(yīng)用.
 
Basic™ (BASiC Semiconductor) second generation SiC silicon carbide MOSFET has two main features:
1. Outstanding reliability: Compared with competing products, there is sufficient design margin to ensure device reliability during mass manufacturing.
The breakdown voltage BV value of BASiC Semiconductor's second-generation SiC silicon carbide MOSFET 1200V series is measured to be around 1700V, which is higher than mainstream competing products on the market. The breakdown voltage BV design margin can withstand silicon carbide substrate epitaxial materials and wafers. The swing of the tape-out process can ensure device reliability during mass manufacturing, which is the most critical quality of BASiC Semiconductor’s second-generation SiC silicon carbide MOSFET. BASiC Semiconductor’s second-generation SiC silicon carbide MOSFET The relatively high avalanche tolerance margin also enhances reliability in power electronic system applications.
2. Remarkable device performance: Smaller Crss with the same specifications brings excellent switching performance.
BASiC Semiconductor's second-generation SiC silicon carbide MOSFET reverse transmission capacitor Crss is relatively small among mainstream competing products on the market, and its turn-off loss Eoff is also very good among mainstream products on the market, better than some overseas competing products. , especially suitable for LLC applications, typical applications such as charging pile power module downstream DC-DC applications.
 
Ciss:輸入電容(Ciss=Cgd+Cgs) ⇒柵極-漏極和柵極-源極電容之和:它影響延遲時(shí)間;Ciss越大,延遲時(shí)間越長(zhǎng)。基本™(BASiC Semiconductor)第二代SiC碳化硅MOSFET 優(yōu)于主流競(jìng)品。
Crss:反向傳輸電容(Crss=Cgd) ⇒柵極-漏極電容:Crss越小,漏極電流上升特性越好,這有利于MOSFET的損耗,在開(kāi)關(guān)過(guò)程中對(duì)切換時(shí)間起決定作用,高速驅(qū)動(dòng)需要低Crss。
Coss:輸出電容(Coss=Cgd+Cds)⇒柵極-漏極和漏極-源極電容之和:它影響關(guān)斷特性和輕載時(shí)的損耗。如果Coss較大,關(guān)斷dv/dt減小,這有利于噪聲。但輕載時(shí)的損耗增加。
