Taiwan Semiconductor, a global supplier of discrete power electronics devices, LED drivers, analog ICs, and ESD protection devices, announces its new TESD Series of single-channel ESD clamping diodes offering size and performance specifications optimised for wearable applications.

The new TESD devices’ design features proprietary bidirectional clamping cells (for ESD protection up to ±30kV) in an small DFN0603 package.

The devices in the new TESD Series are offered in versions with 5.0V and 3.3V (max.) operating voltages and provide protection in compliance with IEC61000-4-2 (ESD) to ±20kV (air/contact) and IEC61000-4-5 (lightning) to 4.5A (8/20µs). A second 3.3V model in the series increases these specs to ±30kV and 8.2A, respectively.

“Compared to handheld products, wearable products must meet more stringent package size requirements along with ESD standards – so our TESD series’ DFN0603 package offers clear advantages,” said Sam Wang, Vice President, TSC Products. “Besides being the optimum choice for wearable applications, their ultra-small size combined with ultra-low capacitance make these protection devices beneficial in a range of other ESD-sensitive applications, including HDMI, display port and high-speed video I/O; USB 3.0 and 3.1; industrial I/O (RS485); SATA and eSATA; RAID, NAS and SAN systems.”
