Description

The SM4TY series are 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 long term reliability and

stability. SM4TY devices are packaged in SMA (SMA footprint in accordance with

IPC 7531 standard).

SM4T18AY属于电路保护 > TVS - 二极管。意法半导体（ST）集团制造生产的SM4T18AYTVS - 二极管TVS 二极管是一种半导体器件，可用于限制或阻止特定电压电平的浪涌。该系列产品使用二极管（只能单向导电的元器件）进行设计。TVS 是 Transient Voltage Suppression/Suppressor（瞬态电压抑制/抑制器）的首字母缩写。类型包括转向（轨至轨）或齐纳，具有单向通道、双向通道、电压 – 反关态、电压 – 击穿、电压 – 箝位、电流 – 峰值脉冲、功率 – 峰值脉冲和电源线路保护等特征。
