Dealing with transient overvoltage: Leiditech TVS safeguards your circuits

Pain point analysis: Transient overvoltage events, such as lightning strikes and surges, can easily damage expensive core chips. TVS diodes are the "bulletproof vests" in circuits. However, if the supply of core part number such as Nexperia's PTVS series is unstable, the overall risk resistance of the product will be greatly reduced.

Transformation path: The Leiditech TVS diode series, such as the S-P4SMFJ series, can perfectly replace part number like Nexperia's PTVS*VS1UR. These products feature an extremely fast response speed (picosecond level) and strong surge absorption capacity, enabling them to quickly clamp abnormal high voltage within a safe range and provide solid protection for the back-end circuits.
