They have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. The increasing use of electronics technologies in all areas require reliable protection against transient voltages that could damage the electronics circuitry as well as EMI/RFI attenuation to prevent signal distortion and to meet regulatory requirements. AVX TransGuard components help achieve both functions with single component. ## **GENERAL** ## **CHARACTERISTICS** - Operating Temperature: - -55°C to +125°C - Working Voltage: 3.3 - 85Vdc - Case Size: 0402 - 1812 - Energy: 0.05 - 4.2J - Peak Current: 20 - 2000A ## **FEATURES** - Bi-Directional protection - Very fast response to ESD strikes - Multi-strike capability - High Reliability - EMI/RFI Filtering - Wide range of components ## **APPLICATIONS** - IC Protection - Micro Controllers - Relays - I/O Ports - Keyboard Protection - Portable devices - Industrial Controllers - Automation - Smart Grid - Telecom - LED Lights - Cameras - Base Stations - Motion detector - Alarms - and more ## **HOW TO ORDER** |**VC**|**VC**|**1206**|**1206**|||**18**|**D**|**D**||**400**|**400**|**R**|**R**|**P**|**P**| |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| |**Case**

## **PULSE DEGRADATION** 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. ## **ESD TEST OF 0402 PARTS** **==> picture [191 x 201] intentionally omitted <==** **----- Start of picture text -----**
