RS-485 ESD, Lightning, & Power Fault Protection

Littelfuse RS-485 ESD, Lightning, and Power Fault Protection feature polymeric positive temperature coefficients (PPTCs) that can protect against short circuit and power crosses. The RS-485 product line includes the resettable PPTCs, TVS diodes, GDTs, and SIDACtor series. The TVS Diode Arrays and SM712 series are specifically designed to protect RS-485 applications from ESD, EFT, and lightning-induced surges. When lightning occurs, the SIDACtor will react by causing voltage to increase across PPTC until GDT fires.
