Silicon ESD (SESD) Overview

TE Connectivity Silicon ESD (SESD) protection devices help protect electronic circuits against damage from electrostatic discharge (ESD) events. The 0201-size SESD device’s miniature footprint - measuring 0.6mm x 0.3mm x 0.31mm - is approximately 70 percent smaller than prior-generation devices, offering designers flexibility in space-constrained applications.

The SESD0201C-006-058 is a bi-directional and ultra-low capacitance 0.6 picofarad (pF) device that is suitable for protecting very-high-speed data lines, such as USB and HDMI, or low-voltage antenna ports. The device’s ultra-low capacitance, low insertion loss (<0.5dB up to 3GHz), and high linearity of capacitance vs. frequency helps minimize signal degradation.

The SESD0201C-120-058 is a higher-capacitance (12pF) device that can be used for low-speed generic interfaces such as keypads, power buttons, speakers, and microphone ports in portable electronics. Both the SESD0201C-006-058 and SESD0201C-120-058 devices offer 8kV contact and 15kV air discharge protection per the IEC61000-4-2, level 4 standard.

Also included in the product line is the SESD0402S-005-054 device, an ultra-low-capacitance SOD-923 (0402-size package) device with 0.5pF typical capacitance. This device offers a 10kV contact discharge rating per IEC61000-4-2, level 4 and can be used with digital applications such as USB and HDMI.

PESD Overview

TE Connectivity's PESD electrostatic discharge (ESD) protection devices help protection I/O ports on HDMI 1.3, portable video players, LCD & plasma TVs, USB 2.0, digital visual interface (DVI), and antenna switches. PESD devices shunt ESD away from sensitive circuitry in HDTV equipment, printers, laptops, cellular phones, and other portable devices.

PESD devices offer many advantages over traditional protection devices, such as Zener diodes and multi layer varistors (MLVs), which may degrade or distort the signal in high data rate circuits. Compared to transient voltage suppression (TVS) diodes and miniature gas discharge tubes (GDTs), PESD devices provide a more compact form factor and an economical solution for the shrinking profiles of today's compact information appliances.

PESD protection devices provide low capacitance, and meet transmission line pulse (TLP) testing, as well as IEC61000-4-2 testing.
