1. Product Overview:

️· Type: Multilayer Varistors (MLVs)
️· Application: Designed for protecting USB interfaces from transient voltage events (surges, ESD). These are commonly used in electronic devices to safeguard sensitive components.

2. Series: There are several variants within the "USB Series" (USB0001, USB0005, USB0006, USB0002, USB0004). They vary in dimensions and electrical characteristics.

Explanation of Terms:

️· DC Working Voltage: The maximum continuous DC voltage that can be applied without damage.
️· AC Working Voltage: The maximum continuous AC voltage that can be applied. (Note: Often limited by the AC voltage’s peak value).
️· Breakdown Voltage: The voltage at which the varistor starts to conduct significant current.
️· Leakage Current: A small amount of current that flows through the varistor when a voltage is applied. Lower leakage current is better.
️· Transient Energy Rating: The amount of energy the varistor can absorb in a short, high-energy pulse (specified as Joules).
️· Peak Current Rating: The maximum current the varistor can handle during a short pulse.
️· Capacitance: A measure of the varistor's ability to store an electrical charge.

4. Physical Dimensions & Pad Layout

️· The text provides dimensions and pad layouts for each variant (USB0001, USB0002, USB0004, USB0005/0006). The dimensions are given in millimeters (mm) and inches. The pad layout diagrams show the suggested placement of components around the varistor.
️· The diagrams include labels like "L", "W", "T", "BW", "BL", "P" and others that refer to specific dimensions and features of the part and how it should be mounted.

5. Applications: The datasheet implies that these are used in USB ports of electronic devices.

6. Datasheet Notes and Important Information

️· N/A Values: Several electrical parameters are marked "N/A" (Not Available) in the table. This likely means those specifications were not tested or are not a key characteristic for those specific variants.
️· "REF" for Dimension: The term "REF" in the dimensions table means "Reference". It suggests a typical or target value but allows for slight variations in the manufacturing process.
