概览
CM1230 是 CSP 尺寸规格的 2、4 和 8 沟道超低电容 ESD 保护二极管阵列系列。它适用于保护具有较高数据和时钟速率的系统，或需要低电容负载的电路。每个沟道都包括一对 ESD 二极管，它们充当箝位二极管将 ESD 电流脉冲转向正或负电源轨。在正负电源轨之间集成一个齐纳二极管。这样可以保护 VCC 电源轨免受 ESD 尖峰影响，同时不再需要旁通电容器来吸收接地的正 ESD 尖峰。每个沟道都可以安全地消除 ± 8kV的 ESD 尖峰，满足 IEC61000-4-2 国际标准的 4 级要求，以及符合 IEC61000-4-2 技术规范的 ±15kV 空气放电要求。
- I/O port protection including USB, 1394 and serial ATA
- LCD and camera data lines in wireless handsets that use high-speed serial interfaces.
- mobile handsets,
notebook computers, DSCs, MP3 players,
PDAs, etc.
- Two, four, and eight channels of ESD protection
- Low loading capacitance of 0.8pF typical
- Channel I/O to GND capacitance difference of 0.02pF typical is ideal for differential signals
- Minimal capacitance change with temperature and voltage
