DS9503 ESD Protection Diode with Resistors SPECIAL FEATURES
... Thus, the diode absorbs the energy while the resistors further isolate and protect the circuit at the other side of the package. If used with circuits that already have a strong ESD–protection at their I/O port, the ESD protection level is raised to more that 27 kV (IEC 801–2 Reference model). In ca ...

Some hints regarding Thevenin Equivalents and Circuits with
... Normally, one can find RTH by using RTH = (VOC / ISC ). However, what is the value of 0V/0A ??? The answer: we do not know. (RTH is NOT equal to 2R || R. You can only zero out independent sources.) A different approach is needed. RTH is the resistance seen looking back into the circuit when all inde ...

Mains electricity
Mains electricity is the general-purpose alternating-current (AC) electric power supply. In the US, electric power is referred to by several names including household power, household electricity, house current, powerline, domestic power, wall power, line power, AC power, city power, street power, and grid power.The two principal properties of the electric power supply, voltage and frequency, differ between regions. A voltage of (nominally) 230 V and a frequency of 50 Hz is used in Europe, most of Asia, most of South America and Australia. In North America, the most common combination is 120 V and a frequency of 60 Hz. Other voltages exist, and some countries may have, for example, 230 V but 60 Hz. This is a concern to travelers, since portable appliances designed for one voltage and frequency combination may not operate or may be destroyed by another.The use of different plugs and sockets in different regions provides some protection from accidental use of appliances with incompatible voltage and frequency requirements.
