RIVERSIDE, Calif. - Bourns, Inc., announced its new Model TBU-DF and TBU-DB-Q high-speed protector (HSP) device families. These extremely fast (react in <1 millisecond), very precise semiconductor-based protectors provide a simple-to-use data line protection solution that offers inherent coordination with peripheral circuitry and fewer variables that the designer has to consider.
The TBU-DF model is designed to meet the protection needs of RS-485 interfaces that are used for data collection and remote sensing in new IoT, factor and home automation applications and in process control and test and measurement equipment. The AEC-Q101-compliant Model TBU-DB-Q Series matches the protection needs of battery sensing/balancing applications such as those in new battery management systems (BMS).
Bourns' new TBU-DF and TBU-DB-Q Series products are low capacitance dual bidirectional high-speed Electronic Current Limiter (ECL) devices offered in surface mount DFN packaging. They are constructed using MOSFET semiconductor technology. When placed in the system circuit, they monitor the current using an integrated detection circuitry that triggers during large voltage or current transient events providing an effective barrier that protects sensitive electronics.
Bourns TBU-DF and TBU-DB-Q device families are available now, are RoHS compliant* and are IEC 61000, IEC 61000-4-2, IEC 61000-4-4 and IEC 61000-4-5 compliant.
