Taiwan Semiconductor’s new ESD protection devices

All DFN0603-packaged models in the 3.3V and 5.0V TESDx Series exceed the 8kV IEC61000-4-2 20kV contact discharge standard as well as IEC6100-4-5 4A peak pulse current, with margin. TESDx Series devices utilize Taiwan Semiconductor’s proprietary clamping cells to prevent overvoltage damage from ESD and lightning on control, power and data lines. Additionally, their industry’s lowest capacitance allows for full USB 3.0 data rates without compromise.

Applications for the new 3.3V/5.0V ESD protection series include wearable products, portable medical and test and measurement instrumentation and IoT and IIOT devices. Other applications include consumer electronics, computing, networking, peripherals, USB3.X ports and any application where ESD protection is needed — and where size is a top-of-mind concern.

The TESDx Series offers three models to choose from:

• TESDH3V3B03P1Q0 - 3.3V/40W - 0.2pF
• TESDL3V3B23P1Q0 - 3.3V/70W - 17pF
• TESDH5V0B03P1Q0 - 5.0/100W - 0.2pF

“For wearables and other high-density electronic products, the devices used for ESD protection should be as small and thin as possible, so our new DFN0603-packaged devices are an ideal choice,” said Sam Wang, vice president, TSC Products. “The 3.3- and 5.0-volt models in the series provide full-compliance electrostatic discharge and electronic fast-transient protection, with margin. When protecting high-speed data signals, they also offer extremely low capacitance to ensure that the signal integrity in the application remains within spec and uncompromised.”
