Basic Device Operation (Continued)

COORDINATION

In all applications, the overvoltage protection device should be

chosen to limit the maximum voltage across the Bourns

TCS

™

High-Speed Protector to less than the maximum voltage rating

of the device. If this maximum voltage limit is exceeded, the

Bourns

TCS

™

High-Speed Protector may begin to avalanche,

and it will cease to effectively block the current into the

protected device, which may result in damage.

USING MULTIPLE TCS-DL DEVICES IN SERIES OR

PARALLEL

Bourns

TCS

™

High-Speed Protectors may be connected in

parallel to achieve even lower on-state resistance. If matching

is required, use two Bourns

TCS-DL Series HSPs, and connect

one Bourns

TCS

™

High-Speed Protector from each DL device

in parallel. In addition, because of their ultra-fast response, mul-

tiple Bourns

TCS

™

High-Speed Protectors may be connected in

series to achieve multiples of the breakdown voltage.

Reference Applications

Two good examples of applications where the combination of

a Bourns

TCS

™

High-Speed Protector and a voltage limit-

ing device provides exceptional performance are in VDSL

and Ethernet circuits, where the line is driven differentially by a

transformer.

Users should verify actual device performance in their speciﬁc applications.

GbE

In the Gigabit Ethernet (GbE) application circuit shown below,

the transformer provides additional protection against sustained

DC faults and provides some isolation from surge conditions

such as lightning strikes. The TCS™ device limits the current

that the PHY will be subjected to under a surge condition. It

also provides voltage isolation so that the peak voltage that the

PHY is subjected to will be lower than the TVS diode

clamp voltage. The TVS diode will sink the majority of

the transformer secondary current and clamp the voltage

to a level that is below the 40 V maximum rating of the

TCS™ device.

Gigabit Ethernet Application Circuit

VDSL

In the VDSL application shown below, the transformer provides

additional protection against sustained DC faults and the cou-

pling capacitors, C1 and C2, provide protection against DC and

mains frequency power faults. The termination resistors

R1 and R2 are reduced in value by the nominal resistance of

the Bourns

TCS

™

High-Speed Protector to maintain the overall

termination resistance.

High-Speed

Protectors have a matte-tin

termination. The recommend-

ed solder stencil thickness

is 0.10 to 0.12 mm (0.004

to 0.005 in.). The stencil

opening for pins 1,3,4 and

6 should be the same size

as the recommended PCB

pad size. The stencil open-

ings for pins 2 and 5 of the

device should cover 60-70 %

of the area of the PCB pad

and should be divided into

smaller areas as shown in

the solder stencil gure.
