TransGuard® AVX Multilayer Ceramic Transient Voltage Suppressors GENERAL DESCRIPTION The AVX TransGuard® Transient Voltage Suppressors (TVS) with unique high-energy multilayer construction represents state-of-the-art overvoltage circuit protection. Monolithic multilayer construction provides protection from voltage transients caused by ESD, lightning, NEMP, inductive switching, etc. True surface mount product is provided in EIA industry standard packages. Thru-hole components are supplied as conformally coated axial devices. TRANSGUARD® DESCRIPTION TransGuard® products are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current characteristics (bi-directional) similar to back-to-back zener diodes. They have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO grains surrounded by electrically insulating barriers, creating varistor-like behavior. The number of grain-boundary interfaces between conducting electrodes determines “Breakdown Voltage” of the device. High voltage applications such as AC line protection require many grains between electrodes while low voltage requires few grains to establish the appropriate breakdown voltage. Single layer ceramic disc processing proved to be a viable production method for thick cross section devices with many grains, but attempts to address low voltage suppression needs by processing single layer ceramic disc formulations with huge grain sites has had limited success. AVX, the world leader in the manufacture of multilayer ceramic capacitors, now offers the low voltage transient protection marketplace a true multilayer, monolithic surface mount varistor. Technology leadership in processing thin dielectric materials and patented processes for precise ceramic grain growth have yielded superior energy dissipation in the smallest size. Now a varistor has voltage characteristics determined by design and not just cell sorting whatever falls out of the process. Multilayer ceramic varistors are manufactured by mixing ceramic powder in an organic binder (slurry) and casting it into thin layers of precision thickness. Metal electrodes are deposited onto the green ceramic layers which are then stacked to form a laminated structure. The metal electrodes are arranged so that their terminations alternate from one end of the varistor to the other. The device becomes a monolithic block during the sintering (firing) cycle providing uniform energy dissipation in a small volume. 1 TransGuard® AVX Multilayer Ceramic Transient Voltage Suppressors PART NUMBER IDENTIFICATION Surface Mount Devices Axial Leaded Devices Important: For part number identification only, not for construction of part numbers.

The VI curves below show the voltage/current characteristics for the 5.6V, 9V, 14V, 18V and low capacitance StaticGuard parts with currents ranging from parts of a micro amp to tens of amps. Traditionally varistors have suffered degradation of electrical performance with repeated high current pulses resulting in decreased breakdown voltage and increased leakage current. It has been suggested that irregular intergranular boundaries and bulk material result in restricted current paths and other non-Schottky barrier paralleled conduction paths in the ceramic. Repeated pulsing of TransGuard transient voltage suppressors with 150Amp peak 8 x 20µS waveforms shows negligible degradation in breakdown voltage and minimal increases in leakage current. This does not mean that TransGuard suppressors do not suffer degradation, but it occurs at much higher current. 100 VC04LC18V500 VC040218X400 VC040214X300 VC040209X200 VC040205X150 Voltage (V) 80 ESD TEST OF 0402 PARTS 60 35 40 VC04LC18V500 30 0 10-9 10-7 10-5 10-3 10-1 10 103 BREAKDOWN VOLTAGE (Vb) 20 105 Current (A) 25 20 VC040214X300 15 VC040209X200 10 PEAK POWER VS PULSE DURATION VC040218X400 VC040205X150 1300 5 10 100 1200 1000 10000 8kV ESD STRIKES 1100 900 800 0 -5 700 600 -10 dB PEAK POWER (W) INSERTION LOSS CHARACTERISTICS VC040218X400 VC040214X300 VC040209X200 VC04LC18V500 VC040205X150 1000 500 400 300 VC04LC18V VC040218X -15 VC040214X VC040209X VC040205X -20 200 -25 0.01 100 10 100 IMPULSE DURATION (µS) 4 0.1 1 Frequency (GHz) 0 1000 10 TransGuard® AVX Multilayer Ceramic Transient Voltage Suppressors VOLTAGES = 3.3, 5.6, 9, 14, 18, 26 OR 30 VDC 0603 SURFACE MOUNT Dimensions: Actual Size: Length Width Thickness Termination Band Width Termination Separation Termination Finish 1.6 ± 0.15mm (0.063" ± 0.006") 0.50 ± 0.15mm (0.032" ± 0.006") 0.9mm Max.
