At the IEEE MTT-S International Microwave Symposium here today, Infineon Technologies announced the availability of a family of low capacitance transient voltage suppressor (TVS) diode arrays designed to provide electrostatic discharge (ESD) protection for such high speed data interfaces as USB2.0, 10/100 Ethernet, Firewire, video and LAN/WAN ports.


Offering the industry’s lowest line capacitance and smallest packages, the ESD8V0L family is ideal for space-constrained 3.3/5/12 V mobile communication and consumer applications, including mobile phones, PDAs, MP3 players, LCD displays, printers and notebook computers.

The industry-leading capacitance/package combination of the ESD8V0L diode arrays offers a number of advantages. A capacitance as low as 2 pF increases design flexibility by allowing designers to allocate more of their capacitance budgets to other areas, such as trace wires and interfaces. Additionally, use of TSLP packages, with the smallest form factor available (1 mm x 0.6 mm x 0.4 mm, max.), reduces the footprint necessary to implement ESD protection; in a typical example, a popular PDA uses almost 40 Infineon diode arrays for such applications as audio, SIM card, thumbwheel and display protection.

The ESD8V0L arrays exceed the IEC61000-4-2 Level 4 requirements by providing contact discharge protection for up to 25 kV. They also meet or exceed the IEC61000-4-4 and IEC61000-4-5 standards. Other features include a typical reverse current of 1 nA, a series inductance as low as 0.4 nH, a clamping voltage of 20 V and a peak pulse current of 2.5 A.

The ESD8V0L TVS diode arrays are available now in both single-channel and two-channel bi-directional configurations in a lead-free, RoHS-compliant 1 mm x 0.6 mm x 0.4 mm TSLP package. In quantities of 10,000, the single-channel ESD8V0L1B-02LRH is priced at $0.044 and the two-channel ESD8V0L2B-03L is $0.067.
