ESD (electrostatic discharge) protection devices are 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 protection devices provide exceptionally low capacitance, 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.
