  • High-efficiency clamping protection for power surges and ESD protection (with TVS clamping diodes and arrays, or Transils™)
  • Additional application-specific protection including serial current limiters, thermal shutdown, CMOS and SPI interfaces.

Standard and advanced innovative packages (flow-through µDFN, WLCSP and PowerQFN) keep board space to a minimum, helping improve layout options.

ST is now offering online ESD design tools with the TVS smart selector.
