产品概述

SS320F 产品概述

一、概述

SS320F 为晶导微电子出品的肖特基整流二极管，单体峰值整流电流3A，直流反向耐压达200V，采用SMAF小型封装。肖特基结构赋予其低正向压降、快速恢复特性，适合中功率、高效率电源及保护电路应用。

二、主要特点

正向压降：Vf = 950mV @ 3A（典型），降低导通损耗。
反向耐压：Vr = 200V，满足中高压整流要求。
反向电流：Ir = 300µA @ 200V，漏电小，有利于高阻抗回路与待机功耗控制。
最大整流电流：IF = 3A（直流）；非重复峰值浪涌电流Ifsm = 80A，具备较强浪涌承受能力。
工作结温范围：-55℃ ～ +125℃，适应宽温度环境。
封装：SMAF，体积小，便于自动贴装和密集布局。

三、电气与热性能要点

导通损耗估算：P ≈ Vf × IF（例如3A时约2.85W），需结合PCB散热设计控制结温。
建议在大电流应用中增加焊盘铜厚或散热铜箔，若靠近高热源应留出散热通道。
避免在超过额定Ifsm的条件下反复冲击，以免影响寿命。

四、典型应用

开关电源及快恢复整流
DC-DC转换器输出整流
反向极性保护、电池充放电管理
太阳能逆变器、工业电源、车载电子（需评估工作电压及温度）

五、封装与可靠性

SMAF 封装兼顾热性能与占板面积，适合SMT生产。产品经过常规电气和温度循环验证，推荐在元件周围保留合理散热铜地和热焊盘以提升长期可靠性。

六、使用与存储注意事项

推荐在合适的回流焊曲线下焊接，避免长时间超温；存储时防潮、防静电。
在设计时预留安全裕量（电流、电压及浪涌能力），并考虑实际工作温升对Vf和Ir的影响。

七、订购信息

型号：SS320F；品牌：晶导微电子；封装：SMAF。订购前请参考最新规格书以确认详细引脚、尺寸图和完整电气特性。
