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.

NC = Solder to PCB; do not make electrical
connection, do not connect to ground.
TBU™ protectors have matte-tin termination finish. Suggested layout should use non-solder mask define (NSMD). Recommended stencil
thickness is 0.10-0.12 mm (.004-.005 in.) with stencil opening size 0.025 mm (.0010 in.) less than the device pad size. As when heat sinking
any power device, it is recommended that, wherever possible, extra PCB copper area is allowed. For minimum parasitic capacitance, do not
allow any signal, ground or power signals beneath any of the pads of the device.
