Tyco Electronics has added three new devices to its line of electrostatic discharge (ESD) protection devices. Included in this launch is an 0201-sized Silicon ESD (SESD) device, which is approximately 70 percent smaller than prior generation 0402-sized devices and helps provide protection and improve reliability of portable electronics such as mobile phones, MP3 players, PDAs and digital cameras.
The SESD device’s miniature footprint — measuring a mere 0.6mm x 0.3mm x 0.3mm – offers designers flexibility in space-constrained applications. Bi-directional operation allows placement on the PCB without orientation constraints and won’t clip signals that swing below ground. Designed to withstand IEC61000-4-2, level 4 ESD test pulses, the SESD device helps protect sensitive integrated circuits (ICs).
The SESD0201C-006-058 device is a bi-directional and ultra-low capacitance 0.6 picofarad (pF) device that is suitable for helping to protect very-high-speed data lines, such as USB and HDMI, or low-voltage antenna ports.
The SESD0201C-120-058 device 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.
The SESD0402S-005-054 device, an ultra-low capacitance SOD-923 (i.e. 0402-size package) device with 0.5pF typical capacitance, and a 10kV contact discharge rating per IEC61000-4-2, level 4 that could be used for digital applications such as USB and HDMI.
