The ESD SOT143 is a highly reliable and professional-grade product that is designed to meet the strict standards set by IEC 61000-4-2 for Electrostatic Discharge (ESD) protection. 

In addition to ESD protection, the ESD SOT143 also complies with IEC 61000-4-4 for Electrical Fast Transients (EFT). It can handle a maximum current of 40A with a fast rise time of 5/50 nS, providing excellent immunity against transient disturbances commonly encountered in industrial environments.

Furthermore, this product is compatible with IEC 61000-4-5 for Surge protection. It offers a surge current rating of 24A and is capable of handling surge events with a duration of 8/20 uS. With both Level 2 (line-GND) and Level 3 (Line-Line) surge protection, the ESD SOT143 ensures that your equipment remains safe and operational even during severe surge events.

Choose the ESD SOT143 for its exceptional compatibility with international standards and its ability to provide reliable protection against ESD, EFT, and Surge events. With its professional-grade performance, this product is the ideal choice for industries that demand the highest level of protection for their sensitive electronic devices.
