TBU-DT Series is preferred.
P650-U and P850-U Series TBU^® High-Speed Protectors
Transient Blocking Units - TBU^® Devices
Bourns^® Model P650-U and P850-U products are high-speed,
unidirectional 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.
