TRANSIENT VOLTAGE SUPPRESSORS
Silicon TVS diodes contain a P/N junction similar to a Zener diode but with a larger cross section, which is proportional
to its surge power rating. These diodes are clamping devices that limit voltage spikes by the low impedance avalanche
breakdown of the P/N junction.

Figure 1. Unidirectional V-I Curve
The V-I curve shown in Figure 1 is similar to that of a Zener diode. TVS diodes are designed and characterized for transient
voltage suppression, while Zener diodes are designed and specified for voltage regulation.

A transient is clamped instantaneously and diverts the damaging current away from the protected device. Figure 2 shows
a transient current being diverted to ground. Under normal operating conditions, the TVS presents a high impedance
path to the protected circuit. During the transient event, the TVS achieves breakdown, then presents a low impedance
path, which shunts the transient current through the TVS device.

WHY TVS PROTEK’TION
The ESD association has estimated that the average loss of product due to user-generated ESD at 27% to 33%. This costs
the industry billions of dollars in losses. Transient voltage suppressors prevent system and component failure caused by
ESD, EFT and other transients.
TVS DEVICE SELECTION
A TVS device with the proper characteristics for a given application should:
• Prevent system/component damage
• Optimize circuit performance
The following key parameters should be considered when selecting a TVS device
• Stand-Off Voltage (VWM) - the maximum continuous dc or peak voltage which may be applied over the standard operating temperature range. VWM is normally 10% below the breakdown voltage (VBR).
• Breakdown Voltage (VBR) - the voltage measured across the device at a specified pulsed dc current (IT or IBR) on the
V/I characteristic curve at or near to where the breakdown (avalanche) occurs. Also known as the voltage across the
device in the breakdown region prior to the switching point at a specified breakdown current (IBR).
• Leakage Current (ID) - the maximum current that flows through the device at the rated stand-off voltage (VWM) for a
specified temperature. Also known as Reverse Leakage Current (IR).
• Capacitance (C) - this parameter is associated with high data rate applications and is measured at a specific frequency
and bias. High capacitance degrades signals.
• Forward Voltage (VF) - the voltage across the device in the forward conducting state at a specified current IF.
• Clamping Voltage (VC) - the peak voltage measured across the device during the application of a pulse current (IPP) for
a specified waveform.
• Peak Pulse Current (IPP) - the maximum current handling capability for a given pulse duration (td). The current capability is referenced to a specific waveshape (i.e., 8/20µs, 10/1000µs) and is not constant over time.
• Peak Pulse Power (PPP) - the maximum clamping voltage (VC) multiplied by the maximum peak pulse current (IPP),
where the maximum clamping voltage is considered independent of time.
