Texas Instruments TVS3300 Precision Surge Protection Clamp
Texas Instruments TVS3300 Precision Surge Protection Clamp is a transient voltage suppressor which provides robust protection for electronic circuits exposed to high transient voltage events. Unlike a traditional TVS diode, the TI TVS3300 precision clamp triggers at a lower breakdown voltage and regulates to maintain a flat clamping voltage throughout a transient overvoltage event. The lower clamping voltage combined with a low dynamic resistance enables a unique TVS protection solution to lower the voltage a system is exposed to during a surge event. This reduction can be up to 30% in the unidirectional configuration and up to 20% in the bi-directional configuration compared to traditional TVS diodes. The low clamping voltage and flat clamping performance allow designers to confidently select downstream system components with a higher voltage rating than possible with traditional TVS diodes. This feature helps lower system cost and reduce board area, thus improving overall performance.Features
