技术问答

Central Semiconductor （简称Central）公司是美国中央半导体公司，半导体产品处于世界领先水平，其运营团队提供最高水平的技术支持，出色的销售支持和优质的服务。Central公司推出的硅肖特基二极管—— CMPSH-3系列（CMPSH-3,CMPSH-3A,CMPSH-3C,CMPSH-3S），环氧树脂模塑，采用SOT-23表面贴装封装，专为需要低正向压降的快速开关应用而设计。其具体实物图如图1所示。

图1.CMPSH-3系列硅肖特基二极管实物图

CMPSH-3系列硅肖特基二极管的峰值重复反向电压V_RRM为30V，连续正向电流I_F为100mA，当反向连续电压V_R为25V时，其反向电流I_R的最大值为500nA，具有低反向电流和较高的反向耐压能力。其系列功率损耗P_D的最大值为350mW，功率损耗值极低，还具有较低的正向压降。当正向电流I_F为100mA时，正向压降V_F的最大值仅为1.00 V。产品封装尺寸、引脚说明以及可参考的焊盘轮廓图如图2所示。

图2.CMPSH-3系列硅肖特基二极管封装尺寸、引脚说明以及可参考的焊盘轮廓图

CMPSH-3系列硅肖特基二极管的峰值正向浪涌电流I_FSM为750 mA（tp=10ms），峰值重复正向电流I_FRM为350mA，具备较强的抗浪涌冲击能力。其热阻Θ_JA为357°C/W，结电容的典型值为7.0pF(V_R=1.0V, f=1.0MHz)。工作温度和存储结温范围均为-65℃~+150℃，具有耐高/低温的能力，适应性能强，这提高了其在大功率整流电路设计中的可靠性。反向恢复时间较短，时间trr最大值为5.0ns(I_F=I_R=10mA, I_rr=1.0mA, R_L=100Ω)。另外，其耗散功率与温度均具有负的温度系数，耗散功率对环境温度较为敏感，功率损耗值随着温度的变化而变化。根据设计的需求，可参考功耗温度曲线，通过相应的坐标值，方便产品功耗的设计。具体功率降额曲线如图3所示。
