Tools & Software

Driven by market needs, ST’s ESD protection devices, including transient voltage surge suppressors (TVS), clamping diodes and arrays, or Transils™, focus on:

ESD protection

  • IEC 61000-4-2 compliance
  • Protection efficiency with low clamping voltage
  • Protection reliability with low leakage current
  • Signal integrity with ultralow capacitance and ultrawide bandwidth.

Standard packaging options are available, as well as advanced options which include single- and multiple-line, compact, flat, and flow-through versions to optimize space constraints.

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

Advanced USB ESD protection for cutting-edge microcontrollers

ST offers the industry’s widest range of ESD protection devices for microcontroller-based applications with USB interfaces:

  • USB 2.0 low and full speed, with the USBLC6-2 and -4 series ensuring robust ESD immunity up to 15 kV (contact discharge)
  • USB 2.0 high speed, with the USBULC6-xxx series whose ultra-low capacitance guarantees optimum signal integrity and ESD protection
  • USB 3.1 datalines and Type-C connectors with Power Delivery and Alternate Mode support, with single- (ESDAXLC6-1Bxx) and multi-line ESD protection (HSP061 series) operating at bandwidths up to 10 GHz
  • VBUS pin, kept safe from Electrical Over Stress (EOS) with the ESDA7P60-1U1M transient voltage suppressor featuring 700 W peak pulse power capability

To remove radiated noise from USB 2.0 high-speed and 3.1 links, the ECMF™ series combines both ESD protection and common-mode filtering.
