Transient Voltage Suppression (TVS) Diodes
Littelfuse offers the widest range of TVS Diodes and other circuit protection products.
Littelfuse TVS Diodes are ideal for protecting semiconductor components from
high-voltage transients. They can respond to overvoltage events faster than most
other types of circuit protection. This makes TVS Diodes useful for protecting against
very fast and often damaging voltage transients, such as lightning, inductive load
switching and electrostatic discharge.
Littelfuse TVS Diodes can fit a wide range of circuit protection applications but were
primarily designed to protect I/O interfaces in telecommunication and industrial
equipment, computers and consumer electronics.

Transient Voltage Suppression Diodes
Overvoltage Suppression Facts
The exponential rise time of lightning is in the range
1.2μsec to 10μsec (essentially 10% to 90%) and the
duration is in the range of 50μsec to 1000μsec (50% of
peak values). ESD on the other hand, is a much shorter
duration event. The rise time has been characterized at less
than 1.0ns. The overall duration is approximately 100ns.
Transient Threats – What Are Transients?
Voltage Transients are defined as short duration surges of
electrical energy and are the result of the sudden release
of energy previously stored or induced by other means,
such as heavy inductive loads or lightning. In electrical
or electronic circuits, this energy can be released in a
predictable manner via controlled switching actions, or
randomly induced into a circuit from external sources.
Why are Transients of Increasing Concern?
Component miniaturization has resulted in increased
sensitivity to electrical stresses. Microprocessors for
example, have structures and conductive paths which
are unable to handle high currents from ESD transients.
Such components operate at very low voltages, so
voltage disturbances must be controlled to prevent device
interruption and latent or catastrophic failures.
Repeatable transients are frequently caused by the
operation of motors, generators, or the switching of
reactive circuit components. Random transients, on the
other hand, are often caused by Lightning and Electrostatic
Discharge (ESD). Lightning and ESD generally occur
unpredictably, and may require elaborate monitoring to be
accurately measured, especially if induced at the circuit
board level. Numerous electronics standards groups have
analyzed transient voltage occurrences using accepted
monitoring or testing methods. The key characteristics of
several transients are shown in the table below.
VOLTAGE
CURRENT
Sensitive microprocessors are prevelant today in a wide
range of devices. Everything from home appliances, such
as dishwashers, to industrial controls and even toys use
microprocessors to improve functionality and efficiency.
Most vehicles now also employ multiple electronic
systems to control the engine, climate, braking and, in
some cases, steering, traction and safety systems.

automobiles present transient threats to the entire system.

Careful circuit design should not only factor environmental
scenarios but also the potential effects of these related
components. Table 2 below shows the vulnerability of
various component technologies.
Characteristics of Transient Voltage Spikes
Transient voltage spikes generally exhibit a “double
exponential” wave, as shown below for lightning and ESD.

Transient Voltage Suppression Diodes
Transient Voltage Scenarios
Electrostatic Discharge (ESD)
Inductive Load Switching
Electrostatic discharge is characterized by very fast
rise times and very high peak voltages and currents.
This energy is the result of an imbalance of positive and
negative charges between objects.
The switching of inductive loads generates high energy
transients which increase in magnitude with increasingly
heavy loads. When the inductive load is switched off, the
collapsing magnetic field is converted into electrical energy
which takes the form of a double exponential transient.
Depending on the source, these transients can be as large
as hundreds of volts and hundreds of Amps, with duration
times of 400 milliseconds.
ESD that is generated by everyday activities can far surpass
the vulnerability threshold of standard semiconductor
technologies. Following are a few examples:
t Walking across a carpet:
35kV @ RH = 20%;1.5kV @ RH = 65%
Typical sources of inductive transients include:
t Walking across a vinyl floor:
12kV @ RH = 20%;250V @ RH = 65%
t Worker at a bench:
6kV @ RH = 20%;100V @ RH = 65%
t Poly bag picked up from desk:
20kV @ RH = 20%;1.2kV @ RH = 65%
Even though a direct strike is clearly destructive, transients
induced by lightning are not the result of a direct strike.
When a lightning strike occurs, the event creates a
magnetic field which can induce transients of large
magnitude in nearby
electrical cables.

by other DC motors
in a vehicle. For
example, DC motors power amenities such as power locks,
seats and windows. These various applications of a DC
motor can produce transients that are just as harmful to
the sensitive electronic components as transients created
in the external environment.
A cloud-to-cloud strike
will effect not only
overhead cables, but
also buried cables.
Even a strike 1 mile
distant (1.6km) can
generate 70 volts in
electrical cables.

These examples are common in electrical and electronic
systems. Because the sizes of the loads vary according
to the application, the wave shape, duration, peak current
and peak voltage are all variables which exist in real world
transients. Once these variables can be approximated, a
suitable suppressor technology can be selected.
t Vinyl envelopes:
7kV @ RH = 20%;600V @ RH = 65%

TVS Diode Selection Checklist
Crowbar Device
1. Define Circuit Operating Parameters
The class of suppressors that exhibit a “crowbar”
characteristic is usally associated with 4-layer NPNP silicon
bipolar devices or gas plasma/GDT devices. Upon reaching
a threshold or breakover voltage, further increase in current
flow will cause the device to rapidly conduct with only a few
volts of forward drop. In essence, the line is momentarily
“short-circuited” during the transient event.
Normal operating voltage type in DC or AC:
Device Type Required:
Uni-drectional
Bi-directional
Normal operating voltage in volts:
Maximum transient current (Ipp):
Maximum clamping voltage (Vc):
Operating Temperature Range
Required peak reverse surge power rating:
The minimum and maximum ambient operating temperature
of the circuit in which a device will be applied. Operating
temperature does not allow for the effects of adjacent
components, this is a parameter the designer must take into
consideration.
Product mounting type (package):
Operating temperature:
2. Narrow TVS Diode Series for the Application
Capacitance
Please refer to the product selection charts and data
sheets within this guide, factoring these key parameters:
The property of a circuit element that permits it to store
an electrical charge. In circuit protection, the off-state
capacitance is typically measured at 1 MHz with a 2V bias
applied.
Reverse Standoff Voltage (VR):
The device VR should be equal to, or great than, the
peak operating level of the circuit (or part of the circuit)
to be protected. This is to ensure that TVS Diode does
not clip the circuit drive voltage.
Reverse Standoff Voltage (VR)
In the case of a uni-directional TVS diode, this is the
maximum peak voltage that may be applied in the ‘blocking
direction’ with no significant current flow. In the case of
a bi-directional transient, it applies in either direction. It is
the same definition as Maximum Off-state Voltage and
Maximum Working Voltage.
Peak Pulse Current (IPP):
The Peak Pulse Current (IPP) identifies the maximum
current the TVS Diode can withstand without damage.
The required IPP can only be determined by dividing the
peak transient voltage by the source impedance. Note
that the TVS Diode failure mechanism is a short circuit; if
the TVS Diode fails due to a transient, the circuit will still
be protected.
Breakdown Voltage (VBR)
Breakdown voltage measured at a specified DC test current,
typically 1mA. Usually a minimum and maximum is specified.
Maximum Clamping Voltage (VC):
This the peak voltage that will appear across the TVS
Diode when subjected to the Peak Pulse Current (IPP),
based on 10X1000us exponential waveform. The VC of
each TVS Diode is identified in each series data sheet
electrical characteristics table.
Peak Pulse Current (IPP)
Maximum pulse current which can be applied repetitively.
Usually a 10x1000μs double exponential waveform, but can
also be 8x20μs, if stated.
Maximum Clamping Voltage (VC or VCI)
3. Verify Ambient Operating Parameters
Maximum voltage which can be measured across the
protector when subjected to the Maximum Peak Pulse
Current.
Ensure that the application voltage is less than or equal
to the device’s standoff voltage, and that the operating
temperature limits are within those specified by the device.
Peak Pulse Power (PPP)
4. Verify Device Mounting Style and Dimensions
Expressed in Watts or Kilowatts, for a 1ms exponential
transient (see figure 1, page 23) it is IPP multiplied by VCL.
Please refer to the dimension drawings contained within
the data sheet of each series.
5. Test the Selected Device in Actual Application
Please contact Littelfuse if you would like assistance
with testing and verifying suitability of a Littelfuse device
within your product. We have extensive product testing lab
capabilities and technical expertise to assist you.

Transient Voltage Suppression Diodes
Axial Leaded – 6kA > AK6 series
RoHS
AK6 Series
Description
The new AK6 series of high current transient suppressors
have been specially designed for use in A.C. line
protection and any demanding applications (AC or DC).
They offer superior clamping characteristics over standard
S.A.D. technologies by virtue of the Littelfuse Foldbak™
technology, which provides a clamping voltage lower
than the avalanche voltage (but above the rated working
voltage). Therefore, any voltage rise due to increased
current conduction is contained to a minimum, providing
the best possible protection level. They can also be
connected in series and/or parallel to create very high
capacity protection solutions.

Transient Voltage Suppression Diodes
Axial Leaded – 10kA > AK10 series
RoHS
AK10 Series
Description
The new AK10 series of high current transient suppressors
have been specially designed for use in A.C. line
protection and any demanding applications (AC or DC).
They offer superior clamping characteristics over standard
S.A.D. technologies by virtue of the Littelfuse Foldbak™
technology, which provides a clamping voltage lower
than the avalanche voltage (but above the rated working
voltage). Therefore, any voltage rise due to increased
current conduction is contained to a minimum, providing
the best possible protection level. They can also be
connected in series and/or parallel to create very high
capacity protection solutions.
