Using circuit protection devices to prevent power supply failures

A recent article in Power Systems Design detailed the results of a study on power supply failures. The study surveyed the participants of the Power Supply Design Center LinkedIn group, which has more than 3,000 members, including engineers with many years of experience in power supply design.

Circuit design and layout are important when using TVS devices

Because many electronic devices now connect to other devices via busses using USB, HDMI, or Thunderbolt protocols, designers need to protect these I/O lines from damage caused by external events, such as electrostatic discharges (ESDs) and electrical fast transients (EFTs). As a result, many designers are now using transient voltage suppression (TVS) devices such as TE Circuit Protection’s Silicon ESD (SESD) devices to help prevent failures caused by these hazards.
