Leaded through–hole capacitors have traditionally been the preferred choice for high-voltage applications such as buck and boost dc-to-dc converters, voltage multipliers for flyback converters, lighting ballast circuits, and power supplies for medical, computer, motor control, and telecommunications applications. Unfortunately, these capacitors require a large amount of board space and increase design and assembly costs. S urface M ou n t M L C C s • Electronic transmissions To eliminate any surface arc-over, circuit boards can be conformally coated, or the components are arranged such as to isolate the high-voltage section from other sections of the board. But as with leaded through-hole capacitors, this approach utilizes a great amount of board space and increases design and assembly costs. Encapsulating compounds and conformal coating may make it more difficult to repair, recycle, or discard the circuit board. To address this problem, Vishay has developed an innovative series of high-voltage HVArc Guard® MLCCs that are the industry’s first C0G and X7R surface mount MLCCs designed to prevent surface arc-over. The HVArc Guard® devices provide maximum capacitance in high-voltage ratings and an increased capacitor voltage breakdown through a unique and world wide patented internal design structure that prevents surface arc- www.vishay.com Vishay Intertechnology 5 HVArc Guard® Surface Mount MLCCs (cont’d) over at high voltages. This design facilitates the use of smaller case sizes in high-voltage products, allowing for device miniaturization and reducing component cost. HVArc Guard® capacitors eliminate the need for conformal coating, and are particularly significant as an alternative to leaded through-hole capacitors since they provide double the voltage breakdown capability while requiring much less space. The devices offer voltage ratings from 250 VDC to 2500 VDC, and a capacitance range of 10 pF to 27,000 pF. In fact, the HVArc Guard® 27,000-pF MLCC has the highest capacitance value currently available in a surface mount 1206 case size with a X7R dielectric and 1,000-V rating. The next closest capacitance value is 10,000 pF.

As demonstrated in the graph, the impedance of the HVArc Guard® is similar to standard high-voltage surface-mount capacitors. Specific details regarding the impedance of specific HVArc Guard® surface-mount capacitors are available upon request through your local Vishay sales office. 6 Vishay Intertechnology www.vishay.com Application Examples Lighting Ballast Circuits MLCCs used in lighting ballast circuits can be exposed to high voltages, over 1000 VDC in air. A block diagram of typical lighting ballast is shown in Figure 3. The capacitors are prone to both surface arc-over and internal breakdown. In either event, failure may result when surface arc-over causes the circuit to be de-stabilized, which may in turn cause damage to surrounding components even if the capacitor remains temporarily functional. The unique HVArc Guard® capacitor design prevents arc-over while allowing the use of smaller case sizes in lighting ballast applications.

New HVArc Guard® high-voltage MLCCs can replace many of these standard high voltage capacitors in ballast circuits, allowing more compact designs while reducing component cost. 500 0 Conventional 100 nF X7R HVArc Guard® 100 nF X7R HVArc Guard® 150 nF X7R HVArc Guard® 22 nF C0G (NP0) 1206 case size Figure 4 compares standard surface mount high-voltage MLCCs and the HVArc Guard® replacements for lighting ballast applications. For example, a common 630 V MLCC in a 1206 case (0.126 in. by 0.063 in.) can be replaced with a HVArc Guard® MLCC in the 0805 case (0.079 in. by 0.049 in.). Using HVArc Guard® can provide board space savings of 50 % or more. The small size dimensions and high-voltage breakdown performance of HVArc Guard® surface-mount MLCCs make these devices ideal for compact electronic fluorescent lighting ballasts, where they will be used in the high-voltage inverter section. Their breakdown voltage is in fact more than twice that of the comparable standard high-voltage capacitor. www.vishay.com Vishay Intertechnology 7 HVArc Guard® Surface Mount MLCCs (cont’d) Low-Power Voltage Multipliers Voltage multipliers can generate very high voltages due to an inverter circuit that feeds a step-up transformer, which is connected to the multiplier circuit. An example of a typical voltage multiplier, which is simply a circuit comprised of capacitors and diodes that charge and discharge in alternating half cycles of the applied AC voltage, is shown in Figure 5. Figure 5 HVArc Guard® Capacitors H V A rc G uard ® S urface M ou n t M L C C s VIN Out GND Series Multiplier for HV Applications Cascading voltage doubler cells, as shown in the circuit, result in a high-voltage output. Applications for voltage multipliers include flyback converters, where a high voltage is produced from a low battery or supply voltage in medical X-ray systems, air ionizers, and oscilloscopes, and instrumentation requiring a high-voltage power supply. When a high voltage potential is applied at > 1000 V, an arc-over between the terminals, or from terminal to case, will occur. To eliminate any arc-over, an overcoating can be applied to the board, or additional board layout spacing can be added to isolate the high-voltage section from other sections of the board. Although coatings add cost to the process and the design, they are required in some applications to meet electrical safety standards. To avoid having to overcoat the components, coated disk capacitors or conformal coated leaded through-hole capacitors are commonly used in voltage multiplier sections, but they take up a large amount of board space. HVArc Guard® surface-mount capacitors offer designers a space-saving alternative. Because of their special worldwidepatent-pending internal construction technology, Vishay’s HVArc Guard® surface-mount capacitors eliminate the need to conformal coat the part or over-coat the circuit board to prevent surface arc-over. In addition, HVArc Guard® surface-mount capacitors offer cost savings by eliminating the costly manual insertion processes associated with through-hole devices. The basic voltage multiplier is termed capacitive since the circuit can hold and store a charge. By series-connecting HVArc Guard® surface-mount capacitors, low-power voltage multipliers can be designed so that the output voltage increases as the number of cascaded stages increases. Passive Snubbers A simple passive R-C snubber is used in power circuitry to dissipate energy and clamp voltages during turn-on and turn-off cycles. For example, in an application where high-voltage MOSFETs are used as the switching device, rapid changes occur as the drain-to-source voltage steps up during MOSFET operation. These changes create voltage transient noise on the gate of the MOSFET. A capacitor snubber is used on source-drain as a bypass cap for the harmful switching noise. Used in these applications, HVArc Guard® MLCCs will typically require significantly less space than standard high-voltage capacitors. Figure 6 shows an example of a snubber used in a totem pole configured MOSFET circuit.
