SMAJ12A is a transient voltage suppressor with a SMA/DO-214AC RoHS package manufactured by Jinkaisheng. It is designed to protect sensitive components from high voltage surge transients. It features low clamping voltage and low capacitance, making it ideal for protecting automotive electronics or high frequency digital systems. The TVS (Transient Voltage Suppressor) is bi-directional with dual lines each capable of handling 12A. It has a working voltage range of 12V - 55V and a clamping voltage of less than 14V. It also has a response time of less than 1ns and can handle up to 2.5kW of peak pulse power. The RoHS (Restriction of Hazardous Substances) package ensures the device is free from hazardous materials.
