常见肖特基二极管型号选型分析
肖特基二极管优点：
1.正向压降小：通常0.4V左右
2.反向恢复时间极短：最小可达几纳秒
3.大的正向电流：1A---300A之间
肖特基二极管缺点：
1.反向工作电压VR低：通常最大才200V
2.漏电流稍大些：最大可达几个mA
小结：肖特基二极管是一种低功耗、超高速半导体器件，广泛应用于开关电源、变频器、驱动器等电路，作高频、低压、大电流整流二极管、续流二极管、保护二极管使用，或在微波通信等电路中作整流二极管、小信号检波二极管使用。
例1：SBT2045LCT
1.反向最大工作电压VRRM:45V
2.正向压降VF:最大0.4V(IF=10A)
3.漏电流IR=120UA
4.浪涌电流IFSM=100A(T=8.3ms)
例2：1N5817,1N5818,1N5819
1.反向最大工作电压VRRM(1N5817,1N5818,1N5819 ):20V,30V,40V
2.正向压降VF:最大0.6V(IF=1.0A)
3.漏电流IR=0.1mA(VRRM=40V)
4.整流电流IF=1A
5.浪涌电流IFSM=25A(T=10ms)
