ESD clamping diodes are optimised for wearable devices

The TESD series of bi-directional proprietary clamping diodes are available from Taiwan Semiconductor in small DFN0603 packages. They provide ESD protection up to ±30kV.

The single-channel ESD clamping diodes offer size and performance specifications optimised for wearable applications, said the company. They feature proprietary bi-directional clamping cells in the small DFN0603 package. 

The diodes 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,” explained Sam Wang, vice president, TSC Products. In addition, they are suitable for 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; RAID, NAS and SAN systems.

Samples are in stock now and production quantities are available in 12 weeks.

Recognised for more than 40 years for its core competence in discrete power rectifiers, Taiwan Semiconductor’s expanded product portfolio includes trench Schottky’s, MOSFETs, power transistors, LED driver ICs, analogue ICs and ESD protection devices. 

TSC’s production facilities in China and Taiwan are fully compliant with current automotive and environmental standards such as IATF16949, ISO9001 and ISO14001.

Taiwan Semiconductor products are used in automotive, computer, consumer, industrial, telecomms and photovoltaic applications.
