SM15T22AY屬于電路保護的TVS-二極管。由意法半導體集團制造生產的SM15T22AYTVS - 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。

描述 Description

The SM15TY Transil series has been designed to protect sensitive automotive circuits against surges defined in ISO 7637-2 and against electrostatic discharges according to ISO 10605.

The Planar technology makes it compatible with high-end circuits where low leakage current and high junction temperature are required to provide reliability and stability over time. SM15TY are packaged in SMC (SMC footprint in accordance with IPC 7531 standard).
