Description

Transient Voltage Suppressors

The SESDPSY0402V05 is a type of ESD protection diodes with ultra-low capacitance. It is designed to protect voltage-sensitive components from ESD and transient voltage events. Its excellent clamping capability, low capacitance, low leakage, and fast response time make it ideal for ESD protection on designs where board space is at a premium.

Due to its low capacitance, it is well-suited for use in high-frequency designs such as USB 2.0 high speed and antenna line applications.
