Electrostatic discharge and analog circuits: Preventing the undetectable disaster
Analog circuits are exposed to outside influences most often through input channels by way of op amps acting as filters, buffers, or amplifiers. Electrostatic discharge (ESD) results from the direct contact of two things that are at different voltage potential levels and can also be defined as a fast, high current transfer. Analog circuit exposure […]
Transient Voltage Suppressor Diode: What is it?
Transients are sudden high-frequency overvoltages that can destroy a chip. A silicon Transient Voltage Suppressor (TVS) is a circuit protection component that either attenuates (reduces) or filters a transient voltage spike (overvoltage), thus protecting your circuit. Another type of TVS diverts a voltage spike away from your circuit (also known as shunting, clamping, or bypassing.) […]
Diode array filters target differential line pairs
Littelfuse, Inc. has introduced the SP5001, SP5002, and SP5003 Series TVS Diode Arrays (SPA® Diodes). These highly integrated Common-Mode Filters (CMF) provide both electrostatic discharge (ESD) protection and common-mode EMI filtering for systems that use high speed differential serial interfaces. They can protect and filter two (SP5001 and SP5003) or three (SP5002) differential line pairs. […]
