Bourns Introduces Bidirectional Thyristor Surge Protectors Offering Very Low Breakover Voltage

RIVERSIDE, Calif., November 22, 2016 - Bourns, Inc., a leading manufacturer and supplier of electronic components, today announced it has expanded its leading line of bidirectional overvoltage protectors offering very low breakover voltage. Designed to limit damaging overvoltage threats, Bourns latest thyristor surge device provides optimized 2-point protection for transformer windings, low voltage electronics and digital telecommunication lines.

The Bourns® Model TISP4011H1BJ, as with other members of the Model TISP40xxH1BJ series, features very low V(bo) breakover voltage of 10.5V, which allows designers to protect lines of working voltages up to 5.25V. Delivering excellent protection for electrical overstress (EOS) conditions, both models provide low voltage overshoot and low capacitance. Offering a space-saving design, these overvoltage protectors are symmetrical voltage-triggered bidirectional thyristors housed in a surface mount SMB package.
