TVS1400DRVR
单向TVS 14V截止 峰值浪涌电流：43A@8/20us
- 描述
- TVS1400可将高达43A的IEC 61000 - 4 - 5故障电流进行可靠分流，以保护系统免受高功率瞬态冲击或雷击。该器件为满足常见的工业信号线路EMC要求提供了解决方案，可通过42Ω阻抗进行耦合的方式承受高达±2kV的IEC 61000 - 4 - 5开路电压。TVS1400使用独特的反馈机制确保在故障期间发挥精确的平缓钳位能力，保证系统接触电压低于20V。精确的电压调节允许设计人员放心地选择具有较低电压容差的系统组件，不但减少了系统成本和复杂度，而且不损害可靠性。此外，TVS1400还采用2mm×2mm小型SON封装，非常适用于空间受限应用，与业内标准的SMA和SMB封装相比，尺寸减小了70%。极低的器件泄露电流和电容确保最大限度地降低了对受保护线路的影响。为了确保在产品的整个寿命期间提供可靠保护，在高温环境下对TVS1400进行了5,000次重复浪涌冲击测试，但器件性能未发生任何变化。

商品概述
The TVS1400 can reliably divert fault currents of up to 43A according to IEC 61000 - 4 - 5, protecting the system from high - power transient shocks or lightning strikes. This device provides a solution to meet the common EMC requirements of industrial signal lines and can withstand an open - circuit voltage of up to ±2kV according to IEC 61000 - 4 - 5 when coupled through a 42Ω impedance. The TVS1400 uses a unique feedback mechanism to ensure precise and smooth clamping capability during faults, guaranteeing that the system contact voltage remains below 20V. Precise voltage regulation allows designers to confidently select system components with lower voltage tolerances, reducing system cost and complexity without sacrificing reliability.
In addition, the TVS1400 is available in a small 2mm × 2mm SON package, making it ideal for space - constrained applications. It has a 70% smaller footprint compared to the industry - standard SMA and SMB packages. The extremely low device leakage current and capacitance minimize the impact on the protected lines. To ensure reliable protection throughout the product's lifespan, the TVS1400 has been tested with 5,000 repeated surge shocks in a high - temperature environment without any change in device performance.
