Features
Bourns® Model P850-G Series TBU® HSPs
are not recommended for POTS
applications. This series is suited for
applications requiring a dual bidirectional device
where 50 ohms of series resistance is acceptable.
For new SLIC applications, we recommend that
customers evaluate our TBU-PL Series.

P850-G Series Dual TBU® High-Speed Protectors
Transient Blocking Units - TBU® Devices
Bourns® Model P850-G TBU® products are dual 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.
Agency Approval
UL recognized component File # E315805.
Industry Standards
Description
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® devices 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.
