Our advantages    

Chinese manufacturing processes have undergone years of iteration, resulting in mature and reliable technologies. Many international corporations opt for production outsourcing in China. As an electronic components manufacturer in China, our products can fully replace those of major international brands in 99% of applications without the need for testing verification. Our products boast high consistency in quality, reasonable pricing, ample inventory, flexible supply, short lead times, and professional after-sales service.    

Description
The SD20VHHU TVS diode is designed to  replace multilayer varistors (MLVs) in portable  applications such as cell phones, notebooks, and  PDA's. It offers superior electrical characteristics  such as low clamping voltage, low leakage current  and high surge capability. It is designed to protect  sensitive electronic components which are  connected to power lines, from over-stress caused  by ESD (Electrostatic Discharge), EFT (Electrical  Fast Transients) and Lighting.  The SD20VHHU is in a DFN2020-3L package  and will protect one unidirectional line. It may be  used to provide ESD protection up to ±30kV  (Contact and air discharge) according to  IEC61000-4-2 , and withstand peak pulse current  up to 160A (8/20μs) according to IEC61000-4-5.
