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.
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
refl ow profi les.
Electrical Characteristics (Tamb = 25 °C)
The P-G series TBU® devices are bidirectional; specifi cations are valid in both directions.

*RoHS COMPLIANT
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.
*RoHS Directive 2002/95/EC Jan. 27, 2003 including annex and RoHS Recast 2011/65/EU June 8, 2011.

Recommended Pad Layout
TBU® devices have matte-tin termination fi nish. Suggested layout should use non-solder mask
defi ne (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.
Pads 1A and 1 are internally connected; the same for pads 3A with 3, 4A with 4, and 6A with 6.
This allows for one PCB layout to accommodate the Model P850.
