Bourns, Inc. Transient Blocking Unit, 200Ma, Full Reel; Suppressor Type Bourns C650-100-WH

The Transient Blocking Unit (TBU) from Bourns, specifically the C650 series, is designed for high-speed bidirectional protection against faults such as short circuits, AC power cross, induction, and lightning surges. This device operates with a maximum protection voltage of 650V for impulse faults and 300V for continuous faults, making it suitable for various applications including voice and xDSL linecards, process control equipment, and general electronics. The TBU is housed in a compact surface mount DFN package, which minimizes PCB area usage. It features a maximum output current of 200mA and a typical triggering current of 150mA, ensuring effective surge protection while maintaining low quiescent current levels. The device is RoHS compliant and UL recognized, meeting industry standards for safety and environmental regulations. Engineers should consider this TBU for projects requiring reliable surge protection in sensitive electronic applications, particularly where space is a constraint and high-speed performance is essential.
