Taiwan Semiconductor unveils its new TESD Series of single-channel ESD clamping diodes with optimized size and performance for wearable applications. The novel design of the new TESD devices includes bidirectional restraining cells (for ESD protection up to ±30kV) housed in an ultra-compact DFN0603 package.

The devices in the new TESD Series are available in versions with 5.0V and 3.3V (maximum) operating voltages and provide IEC61000-4-2 (ESD) protection to ±20kV (air/contact) and IEC61000-4-5 (lightning) protection to 4.5A (8/20µs). These values are increased to ±30kV and 8.2A, respectively, for a second 3.3V iteration in the series.

Wearable products must satisfy more stringent package size requirements and ESD standards than handheld products. According to Taiwan Semiconductor, the DFN0603 package of the TESD series provides distinct benefits. In addition to being the best option for wearable applications, the ultra-small size and ultra-low capacitance of these protection devices make them useful for a variety of other ESD-sensitive applications, such as HDMI, display port, and high-speed video I/O; USB 3.0 and 3.1; industrial I/O (RS485); SATA and eSATA; and RAID, NAS, and SAN systems.
