Transient Voltage Suppressor TVS

Transient Voltage Suppressor

TVS ：（ Transient Voltage Suppressor）,即瞬态电压抑制器，是一种用于吸收ESD能量、保护系统免受ESD/Surge损害的固态元件。

TVS (Transient Voltage Suppressor), also known as a Transient Voltage Suppressor, is a solid-state component used to absorb ESD energy and protect the system from ESD/Surge damage.

双向TVS可在正反两个方向吸收瞬时大脉冲功率，并把电压箝制到预定水平

优点：响应时间快、瞬态功率大、漏电流低 、箝位电压较易控制、体积小

※双向TVS适用于交流电路，单向TVS一般用于直流电路

A bidirectional TVS (Transient Voltage Suppressor) can absorb instantaneous high pulse power in both forward and reverse directions and clamp the voltage to a predetermined level.

Advantages: fast response time, high transient power, low leakage current, easy control of clamping voltage, compact size.

※Bidirectional TVS is suitable for AC circuits, while unidirectional TVS is typically used in DC circuits.

OJ structure: Adopts a glue-protected structure, then cures it at around 200 degrees Celsius to protect the P-N junction and obtain voltage.

GPP structure: The chip's P-N junction is protected under passivated glass. The glass is made by sintering glass powder at around 800 degrees Celsius, and after cooling, it forms a glass layer. This glass layer is integrated with the chip and cannot be separated by mechanical means.
