概览

FOD2743 光隔离放大器由受欢迎的 KA431 精确编程分路参考和光耦合器组成。该光耦合器是一款与硅光电晶体管进行光耦合的砷化镓 (GaAs) 发光二极管。它具有 3 个参考电压容限等级：2%，1% 和 0.5%。电流传输比 (CTR) 范围为 50% 至 100%。它还具有出色的 50 ppm/°C 温度系数。它主要用作隔离 AC-DC 电源和 DC-DC 转换器中的误差放大器/参考电压/光耦合器功能。使用 FOD2743 时，电源设计者可以减少组件数量，节省紧凑封装设计中的空间。小允差消除了很多应用中的调节需要。该器件采用 8 引脚 DIP 白色封装。

  • AC-DC商用电源

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.)
