General Information

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

reﬂ ow proﬁ les.

TBU-PK Series - TBU® High-Speed Protectors

Functional Block Diagram

Reference Application

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 ﬁ tted between the Tip and Ring

connections and ground.

The TBU® device, constructed using MOSFET semiconduc-

tor 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 oper-

ated, 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 ﬁ tted 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.

Customers should verify actual device performance in their speciﬁ c applications.

Power in One Side of TBU® Device

Total Power in Both Sides of TBU® Device

TBU® High-Speed Protectors have a 100 % matte-tin termination

ﬁ nish. For improved thermal dissipation, the recommended layout

uses PCB copper areas which extend beyond the exposed solder

pad. The exposed solder pads should be deﬁ ned by a solder mask

which matches the pad layout of the TBU® device in size and spac-

ing. 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 signiﬁ cantly

improve the junction to ambient thermal resistance, resulting in

operation at lower junction temperatures with a corresponding

beneﬁ t of reliability. All pads should soldered to the PCB, includ-

ing 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.
