TVS diodes for all protection levels

14 November 2018 Circuit & System Protection

Wüth Elektronik eiSos has expanded its portfolio of TVS (transient voltage suppression) diodes. The diodes are characterised by their short response time and an extremely low terminal voltage, and feature a high ESD dielectric strength with a contact discharge of up to ±30 kV.

WE-TVS diodes in the three series ‘Standard’, ‘High Speed’ and ‘Super Speed’ offer effective protection against electrostatic discharges at all protection levels. The new TVS diodes meet the industrial standards IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5 (surge), and are flame-resistant (UL 94 V-0).

The three WE-TVS series comprise sophisticated TVS diodes for the effective protection of sensitive data lines – for example in the consumer electronics field, such as headsets and accessories, digital cameras, laptops, or USB power-delivery applications (PD). In these areas, the semiconductor components such as ICs and LEDs are often in immediate contact with external interfaces that may be exposed to electrostatic discharges. The Würth Elektronik TVS diodes block the electrostatic discharges and reliably protect these components against direct or delayed interferences or even the complete failure of the end devices.

The diodes are available in three separate series: first, there’s the Standard series for slow interfaces such as RS232, RS485, or power-supply systems. In addition, there are the High Speed and the Super Speed series that have been developed for very fast interfaces such as USB 3.1, HDMI, Thunderbolt or GBit Ethernet, a further characteristic feature of these two series being a small capacitance of as low as 0,12 pF.

The Standard Series is available in both uni- and the bi-directional technologies. The High Speed and Super Speed series can be supplied in a rail-to-rail protective circuit design, which offers the additional benefit of protecting the supply voltage using one and the same component.
