UMD05-523
UMD05-523 is Small Surface Mount Device TVS manufactured by UMD.
UNITED MICRO DEVICE INC. UMD05-523
SOD-523 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 puters, and PDA’s. They offer superior electrical characteristics such as lower clamping voltage and no device degradation when pared to MLVs.
The UMD05-523 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-523 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.
