UMD05-323

_______________________________________________________________________________________ UNITED MICRO DEVICE INC. UMD05-323 _______________________________________________________________________________________ SOD-323 Single Line TVS Diode for ESD Protection Description TVS diodes are designed to replace multilayer varistors (MLVs) in portable applications such as cell phones, notebook computers, and PDA’s. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when compared to MLVs. The UMD05-323 is a Uni-Directional TVS that is designed to provide high overvoltage protection by clamping action and have instantaneous response to transient overvoltages. The SOD-323 is a very small package which allows space saving on high density printed circuit board and also gives the designer the flexibility to protect one line in applications where arrays are not practical.
