TBU-PK Series - TBU® High-Speed Protectors
General Information
Vdd
The TBU-PK Series of Bourns® TBU® products are low capacitance dual bidirectional high-speed
protection components, constructed using MOSFET semiconductor technology, and designed to
protect against faults caused by short circuits, AC power cross, induction and lightning surges.
In addition to overcurrent protection, an added feature is the voltage monitoring on the two lines. If the
voltage on the line drops below Vss then the voltage will trigger the device to switch to the blocking
state.

The TBU® high-speed protector placed in the system circuit will monitor the current with the MOSFET
detection circuit triggering to provide an effective barrier behind which sensitive electronics will not be
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.

Reference Application
Basic TBU Operation
The TBU-PK Series are high-speed protectors used in voice/
VolP SLIC applications. The maximum voltage rating of the
TBU® device should never be exceeded. Where necessary, an
OVP device should be employed to limit the maximum voltage.
A cost-effective protection solution combines Bourns® TBU®
protection devices with a pair of Bourns® MOVs. For bandwidth
sensitive applications, a Bourns® GDT may be substituted for
the MOV. If EN55024 EMC compliance is required, the TBU®
device may require capacitors to be fitted between the Tip and
Ring connections and ground.

The TBU® device, constructed using MOSFET semiconductor technology, placed in the system circuit will monitor the
current with the MOSFET detection circuit triggering to provide
an effective barrier behind which sensitive electronics are not
exposed to large voltages or currents during surge events. The
TBU® device operates in approximately 1 µs - once line
current exceeds the TBU® device’s trigger current Itrigger. When
operated, the TBU® device restricts line current to less than
1 mA typically. When operated, the TBU® device will block all
system voltages and any other voltages including the surge in
each case up to rated limits.
When the voltage on the SLIC output is driven below
(Vbat – Vto) the TBU-PK series device switches to the
blocking state, regardless of output current in the device.
After the surge, the TBU® device resets when the voltage
across the TBU® device falls to the Vreset level. The TBU®
device will automatically reset on lines which have no DC bias
or have DC bias below Vreset (such as unpowered signal lines).
If the line has a normal DC bias above Vreset, the voltage
across the TBU® device may not fall below Vreset after the
surge. In such cases, special care needs to be taken to ensure
that the TBU® device will reset, with software monitoring as
one method used to accomplish this. Bourns application
engineers can provide further assistance.

Notes:
1) The Le9500, Le9520 and Le9530 (VE950 series) require a 200 mA Itrigger TBU® device for normal operation. Other SLIC types should use
the 100 mA device.
2) The MOV maximum continuous rms voltage rating should not be exceeded. The exception is where the data sheet highlights withstand
capability such as the 600 Vrms, 1 A for 0.2 s, for example.
3) If EN55024 EMC compliance is required, the TBU® device may require capacitors to be fitted between the Tip and Ring connections and
ground (i.e. in parallel with the MOV device). The capacitance value can be chosen to meet levels as follows:
• 10 nF for EN55024 Level 1
• 20 nF for EN55024 Level 2
• 47 nF for EN55024 Level 3
Selection of capacitor voltage rating depends upon TBU® part number selection. Recommendations include:
• TBU-PK050 & TBU-PK060 Series: 120 VAC, 500 V Peak Surge Rated
• TBU-PK075 & TBU-PK085 Series: 240 VAC, 750 V Peak Surge Rated
Depending upon the SLIC type, it is usually possible to remove any EMI capacitors present between the output of the SLIC and ground
when using capacitors C1 and C2 in parallel with the MOVs.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.

Recommended Pad Layout
TBU® High-Speed Protectors have a 100 % matte-tin termination finish. For improved thermal dissipation, the recommended
layout uses PCB copper areas which extend beyond the exposed
solder pad. The exposed solder pads should be defined by a
solder mask which matches the pad layout of the TBU® device in
size and spacing. It is recommended that they should be the same
dimension as the TBU® pads but if smaller solder pads are used,
they should be centered on the TBU® package terminal pads and
not more than 0.10-0.12 mm (0.004-0.005 in.) smaller in overall
width or length. Solder pad areas should not be larger than the
TBU® pad sizes to ensure adequate clearance is maintained. The
recommended stencil thickness is 0.10-0.12 mm (0.004-0.005
in.) with a stencil opening size 0.025 mm (0.0010 in.) less than the
solder pad size. Extended copper areas beyond the solder pad
significantly improve the junction to ambient thermal resistance,
resulting in operation at lower junction temperatures with a
corresponding benefit of reliability. All pads should soldered to
the PCB, including pads marked as NC or NU but no electrical
connection should be made to these pads. For minimum parasitic
capacitance, it is recommended that signal, ground or power
signals are not routed beneath any pad.
