Description

The SM30TY 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.

SM30T28AY属于电路保护 > TVS - 二极管。意法半导体（ST）集团制造生产的SM30T28AYTVS - 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。
