1. What is the difference between TVS and varistors?
The main differences between TVS and varistors are their working principles, performance parameters, application scenarios, and prices.
Working Principle
TVS (Transient Voltage Suppressor): TVS forms a PN structure on a silicon-based material and uses the breakdown characteristics of the PN junction to achieve protection. When an overvoltage occurs in the circuit, the resistance value of the TVS changes rapidly, thereby protecting other components in the circuit.
Varistor: Varistors use the nonlinear resistance characteristics of materials such as zinc oxide to achieve overvoltage protection. When an overvoltage occurs in the circuit, the resistance value of the varistor also changes, thereby protecting the circuit.
Performance Parameters
Overvoltage resistance: TVS is usually more resistant to overvoltage than varistors and can withstand higher voltages and currents.
Response time: TVS usually has a shorter response time than varistors and can respond to overvoltage events in a shorter time.
Lifespan: TVS usually has a longer lifespan than varistors because the PN junction of TVS can self-recover after breakdown, while varistors usually break down after a breakdown.

2. What is the difference between varistors and MOVs?
There are some differences between varistors and MOVs (Metal Oxide Varistors) in terms of definition, characteristics, and applications.
Definition and Characteristics
Varistor (VDR/MOV): A varistor is a voltage-sensitive resistor whose resistance value changes with voltage. When an excessively high voltage appears in a circuit, the internal resistance of the varistor drops sharply and turns on quickly, protecting electronic components from surges. MOVs are usually made of zinc oxide and have the characteristics of large current flow, slow response speed, and large parasitic capacitance.
MOV: Specifically refers to metal oxide varistor, which is a type of varistor and is widely used in electronic circuits. Its characteristics include large current flow, slow response speed, and large parasitic capacitance.

3. What are Movs?
Movs(Move String) is an instruction cluster in assembly language, mainly used to copy strings. The Movs instruction cluster includes multiple variants for handling data movement operations of different lengths.
Basic Functions
The main function of the Movs instruction is to copy the data of the DSSI address to the ESDI address. Specifically:
MOVSB: Move one byte at a time.
MOVSW: Move one word (usually two bytes) at a time.
MOVSD: Move one double word (usually four bytes) at a time.

4. What is a Doppler function TVS?
TVS (Transvaginal Sonography) with Doppler function is a non-invasive medical imaging method, mainly used to evaluate the structure and function of the female reproductive system. TVS uses high-frequency acoustic imaging technology to observe the anatomical structure and abnormalities of pelvic organs such as the uterus and ovaries, and is often used for the diagnosis and monitoring of gynecological diseases.
