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

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
