1SMC28AT3屬于電路保護(hù)的TVS-二極管。由安森美半導(dǎo)體公司制造生產(chǎn)的1SMC28AT3TVS - 二極管TVS 二極管是一種半導(dǎo)體器件，可用于限制或阻止特定電壓電平的浪涌。該系列產(chǎn)品使用二極管（只能單向?qū)щ姷脑骷┻M(jìn)行設(shè)計(jì)。TVS 是 Transient Voltage Suppression/Suppressor（瞬態(tài)電壓抑制/抑制器）的首字母縮寫。類型包括轉(zhuǎn)向（軌至軌）或齊納，具有單向通道、雙向通道、電壓 – 反關(guān)態(tài)、電壓 – 擊穿、電壓 – 箝位、電流 – 峰值脈沖、功率 – 峰值脈沖和電源線路保護(hù)等特征。

The SMC series is designed to protect voltage sensitive components from high voltage, high energy transients. They have excellent clamping capability, high surge capability, low zener impedance and fast response time. The SMC series is supplied in ON Semiconductor’s exclusive, cost-effective, highly reliable Surmetic package and is ideally suited for use in communication systems, automotive, numerical controls, process controls, medical equipment, business machines, power supplies and many other industrial/consumer applications.
