MC3423D电路保护的TVS-混合技术规格书PDF中文资料

MC3423D属于电路保护的TVS-混合技术。由安森美半导体公司制造生产的MC3423DTVS - 混合技术混合技术 TVS（瞬态电压抑制器）产品族中的产品属于过压保护产品，其中结合了基于多种技术的保护机制，例如串联连接的 MOV（金属氧化物压敏电阻）和 GDT（气体放电管），旨在同时获得低漏电流和自恢复箝位工作特性。

This overvoltage protection circuit (OVP) protects sensitive electronic circuitry from overvoltage transients or regulator failures when used in conjunction with an external “crowbar” SCR. The device senses the overvoltage condition and quickly “crowbars” or short circuits the supply, forcing the supply into current limiting or opening the fuse or circuit breaker. The protection voltage threshold is adjustable and the MC3423 can be programmed for minimum duration of overvoltage condition before tripping, thus supplying noise immunity. The MC3423 is essentially a “two terminal” system, therefore it can be used with either positive or negative supplies.
