TBU^™ C650 and C850 Protectors
Transient Blocking Units - TBU^™ Devices
Bourns^® C650 and C850 series products are high speed
bidirectional protection components, constructed using
MOSFET semiconductor technology, designed to protect
against faults caused by short circuits, AC power cross,
induction and lightning surges.
The TBU™ high speed protector, triggering as a function of
the MOSFET, blocks surges and provides an effective barrier
behind which sensitive electronics are not 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 as RoHS and Pb Free solder
reflow profiles.
