Speciﬁcations are subject to change without notice.

The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.

Users should verify actual device performance in their speciﬁc applications.

Transient Blocking Units - TBU® Devices

Bourns® Model P500-G and 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

reﬂow proﬁles.

Electrical Characteristics (Tamb = 25 °C)

The P-G series TBU® devices are bidirectional; speciﬁcations are valid in both directions.

Bourns® Model P500-G and 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.
