TVS Diode Arrays (SPA™ silicon protection arrays)
Littelfuse TVS Diode Arrays (SPA™ silicon protection arrays) are designed to protect electronics from very fast and often damaging voltage transients, such as lightning and electrostatic discharge (ESD). They offer an ideal protection solution for I/O interfaces and digital and analog signal lines, in computer and consumer portable electronics markets.
Littelfuse tvs diode arrays are available in a range of packaging configurations including DIP, SOIC, MSOP, SOT23, SOT143, SC70, SOT5x3, SOT953, µDFN, SOD723, and flipchip.
Littelfuse TVS Diode Arrays offer a high level of protection (up to 30kV per IEC 61000-4-2) with very low capacitance, leakage current and clamp voltage. For more robust applications, SP03-xx and SP30xx devices are available for EFT and Lightning transient threats per IEC 61000-4-4/5.
Electrostatic Discharge (ESD) is an electrical transient that poses a serious threat to electronic circuits. The most common cause is friction between two dissimilar materials, causing a buildup of electric charges on their surfaces. Typically, one of the surfaces is the human body, and it is not uncommon for this static charge to reach a potential as high as 15,000 volts. At 6,000 static volts, an ESD event will be painful to a person. Lower voltage discharges may go unnoticed, but can still cause catastrophic damage to electronic components and circuits.
