Raychem Circuit Protection, a business unit of TE Connectivity, now offers PESD0402 and 0603 ESD (electrostatic discharge) protection devices. Designed for I/O port protection in high-speed data transmission applications, PESD protection devices shunt ESD away from sensitive circuitry in electronic devices. The Raychem PESD devices are a preferred solution because traditional protection devices, such as zener diodes and multi layer varistors (MLVs), cannot always be used at higher data rates without degrading or distorting the signal. Alternately, transient voltage suppression (TVS) diodes, and miniature gas discharge tubes (GDTs) may be too large or too expensive for the shrinking profiles of today’s compact information appliances. The Raychem PESD protection devices provide exceptionally low capacitance, and they perform better than other comparable components in transmission line pulse (TLP) testing, as well as IEC61000-4-2 testing, especially after multiple hits (up to 1000). The devices offer a lower trigger voltage and a lower clamping voltage than typical polymer ESD devices, resulting in improved protection of sensitive electronic components.
