Würth Elektronik WE-TVS diodes

Würth Elektronik has expanded its portfolio of TVS diodes. The WE-TVS diodes are characterised by their short response time and a low terminal voltage, and feature a high ESD dielectric strength with a contact discharge of up to ±30 kV.

The diodes in the Standard, High Speed and Super Speed series offer effective protection against electrostatic discharges at all protection levels. They 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 series comprise sophisticated TVS diodes for the effective protection of sensitive data lines — eg, 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 TVS diodes block the electrostatic discharges and protect these components against direct or delayed interferences or even the complete failure of the end devices.

The Standard series diodes are suitable for slow interfaces such as RS232, RS485 or power-supply systems. The High Speed and the Super Speed series have been developed for fast interfaces such as USB 3.1, HDMI, Thunderbolt or Gigabit Ethernet, a further feature of the two series being a small capacitance of as low as 0.12 pF.

The Standard series is available in both the uni- and the bidirectional 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.
