General Information Functional Block Diagram Bourns® Model TBU-RSxxx-300-WH Series is an integrated dual channel
Transient Blocking Unit (TBU) overcurrent device and TVS overvoltage
protector for the RS-485 communications interface. When coupled with an
overvoltage protector like the Bourns® GDT (Model 2030-42T-SM-RPLF) or
TISP® Thyristor Surge Protector (Model TISP4350J3BJR-S), the integrated
solution aids compliance to IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and
IEC 61000-4-5 (Surge) standards (see Application section). Apart from a
reduction in the number of components used, there is also a savings of
52 % in board space when compared to a discrete solution. Media B
