Bourns TBU-PK050-100-WH, Dual-Element Bi-Directional TVS Diode, 8-Pin DFN

The TBU-PK Series of Bourns® TBU® low capacitance dual bidirectional high speed,protection components is constructed using MOSFET semiconductor technology and designed to protect against faults caused by short circuits, AC power cross, induction and lightning surges.,In addition to overcurrent protection, an added feature is the voltage monitoring on the two lines. If the voltage on the line drops below Vss then the voltage will trigger the device to switch to the blocking state.,The TBU® high speed protector placed in the system circuit will monitor the current with the MOSFET detection circuit triggering to provide an effective barrier behind which sensitive electronics will not be exposed to large voltages or currents during surge events. The TBU® device is provided in a surface mount DFN package and meets industry standard requirements such Pb Free solder refl ow profi les. Applications include SLIC protection, Cable & DSL, MDU/MTU modems, ONT and Voice/DSL line cards.

Surface Mount Technology

Resettable fuses are designed for the protection of electrical and electronic circuits against excessive currents. They switch rapidly from a low resistance to very high resistance state under electrical overload or short circuit conditions, and feature automatic reset and return to low resistance state when fault condition ceases and power is removed.

Maintenance free automatic reset for thousands of cycles
Small size and no fuseholder required

Main applications

Security systems
Power supplies and transformers
Power switching devices
Automotive and medical equipment
Instrumentation and control
Computers and peripherals
Audio visual and telecommunications
