IEC 61000-4-2) Application Note: With the VBUS054B-HS3 a double, high speed USB-port or up to 4 other high speed signal or data lines can be protected against transient voltage signals. Negative transients will be clamped close below the ground level while positive transients will be clamped close above the 5 V working range. An avalanche diode clamps the supply line (VBUS at pin 5) to ground (pin 2). The high speed data lines, D1+, D2+, D1- and D2-, are connected to pin 1, 3, 4 and 6. As long as the signal voltage on the data lines is between the ground- and the VBUS-level, the low capacitance PN-diodes offer a very high isolation to VBUS, ground and to the other data lines. But as soon as any transient signal exceeds this working range, one of the PN-diodes starts working in the forward mode and clamps the transient to ground or to the avalanche breakthrough voltage level of the Z-diode between pin 5 and pin 2. t w i n U S B P o r t VBUS D1+ D16 5 4 R E C E I V E R IC 1 2 3 D2+ D2GND 20399 www.vishay.com 4 For technical support, please contact: ESD-Protection@vishay.com Document Number 81586 Rev. 1.4, 07-Oct-08 VBUS054B-HS3 Vishay Semiconductors Background knowledge: A zener- or avalanche diode is an ideal device for "cutting" or "clamping" voltage spikes or voltage transients down to low and uncritical voltage values. The breakthrough voltage can easily be adjusted by the chiptechnology to any desired value within a wide range. Up to about 6 V the "zener-effect" (tunnel-effect) is responsible for the breakthrough characteristic. Above 6 V the so-called "avalanche-effect" is responsible. This is a more abrupt breakthrough phenomenon. Because of the typical "Z-shape" of the current-voltage-curve of such diodes, these diodes are generally called "Z-diode" (= zener or avalanche diodes). An equally important parameter for a protection diode is the ESD- and surge-power that allows the diode to short current in the pulse to ground without being destroyed. This requirement can be adjusted by the size of the silicon chip (crystal). The bigger the active area the higher the current that the diode can short to ground. But the active area is also responsible for the diode capacitance - the bigger the area the higher the capacitance. The dilemma is that a lot of applications require an effective protection against more then 8 kV ESD while the capacitance must be lower then 5 pF! This is well out of the normal range of a Z-diode. However, a Protection diode with a low capacitance PN-diode (switching diode or junction diode) in series with a Z-diode, can fulfil both requirements simultaneously: low capacitance AND high ESD- and/or surge immunity become possible! A small signal (Vpp < 100 mV) just sees the low capacitance of the PN-diode, while the big capacitance of the Z-diode in series remains "invisible". D ZD C TOT C D = 0.4 pF CZ D = 110 pF 20400 I/O Such a constellation with a Z-diode and a small PN-diode (with low capacitance) in series (anti-serial) is a real unidirectional protection device. The clamping current can only flow in one direction (forward) in the PN-diode. The reverse path is blocked. D ZD Gnd 20401 Another PN-diode "opens" the back path so that the protection device becomes bidirectional! Because the clamping voltage levels in forward and reverse directions are different, such a protection device has a Bidirectional and Asymmetrical clamping behaviour (BiAs) just like a single Z-diode.

Depending on the duration of this pulse and the pause to the next one the Z-diodes capacitance can be charged up so that the next pulse "sees" a lower capacitance. After some pulses the big Z-diode could be completely charged up so that the following pulses just see the small capacitance of both PN-diodes. For some application this can work perfectly..... For others applications the capacitance must be the same all the time from the first till the last pulse. For these applications the appropriate mode of use is to connect the Z-diode to the supply voltage. In this mode the Z-diode is charged up immediately by the supply voltage and both PN-diodes are always used in reverse. This keeps their capacitance at a minimum.

Meet all present and future national and international statutory requirements. 2. Regularly and continuously improve the performance of our products, processes, distribution and operating systems with respect to their impact on the health and safety of our employees and the public, as well as their impact on the environment. It is particular concern to control or eliminate releases of those substances into the atmosphere which are known as ozone depleting substances (ODSs). The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs and forbid their use within the next ten years. Various national and international initiatives are pressing for an earlier ban on these substances. Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use of ODSs listed in the following documents. 1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments respectively. 2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental Protection Agency (EPA) in the USA. 3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively. Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting substances and do not contain such substances. We reserve the right to make changes to improve technical design and may do so without further notice. Parameters can vary in different applications. All operating parameters must be validated for each customer application by the customer. Should the buyer use Vishay Semiconductors products for any unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal damage, injury or death associated with such unintended or unauthorized use.
