P6SMB6.8AT3屬于電路保護的TVS-二極管。由安森美半導體制造生產的P6SMB6.8AT3TVS - 二極管TVS 二極管是一種半導體器件，可用于限制或阻止特定電壓電平的浪涌。該系列產品使用二極管（只能單向導電的元器件）進行設計。TVS 是 Transient Voltage Suppression/Suppressor（瞬態(tài)電壓抑制/抑制器）的首字母縮寫。類型包括轉向（軌至軌）或齊納，具有單向通道、雙向通道、電壓 – 反關態(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等特征。

The SMB 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 SMB 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.
