敏感栅极SCR的主要功能是确保对电压峰值的抗扰度,适用于要求严苛的应用,如GFI(接地故障中断)断路器。

意法半导体成功解决了设计挑战 - 保持必要的栅极电流以便在电流低于100µA时进行触发,将驱动功耗降至最低。我们的敏感栅极SCR也可以通过一些有限的系统开销承受高达1200V的电压。

它们的应用范围:采用微型SMB-Flat封装(X0115MUFTS110-8)时可用于GFI断路器,采用TO-220FP封装时可用于摩托车点火。

New SCR optimized for rugged circuit breaker applications

The newcomer to ST’s logic level thyristor family, the TS110-8, is dedicated to miniature circuit breakers. It enables designers to reach a very low power consumption and a high robustness design thanks to its low leakage current and its 1250 V direct surge voltage capability. It provides high off-state immunity (dV/dt=200 V/μs) that ensures the breaker does not trip in case of an electrical fast transient (EFT) on the mains. The TS110-8 is available in the through-hole TO92 package, with two pinout versions, and in the surface-mount 3-lead SMBFlat-3L package.
