The 1.5SMC400CA with ESD Suppressors / TVS Diodes is a unidirectional Transient Voltage Suppressor (TVS) Diode manufactured by Diotec. It has a working voltage of 342V and a maximum peak power rating of 1500W for both ESD (Electrostatic Discharge) suppression applications and general purpose Thunder/Surge protection. The electrical characteristics, including the breakdown voltage, clamping voltage, leakage current, maximum clamp current, rise and fall times, capacitance, and ESD immunity, are optimized for different applications. It is packaged in the SMAJ/SM400CA SOD-323 surface mount package, providing high surge protection for a wide variety of applications where board space is limited.
