SYMBOLS & DEF INIT IONS
Symbol
Definition
αV(BR)
Temperature Coefficient of Breakdown Voltage: The change in breakdown voltage divided by the change i n
temperature that caused it expressed in %/°C or mV/°C.
I
(BR)
Breakdown Current: The current used for measuring breakdown voltage V
(BR)
.
V(BR)
Breakdown Voltage: The voltage across the device at a specified current I(BR) in the breakdown regi on.
VWM
Working Standoff Voltage: The maximum-rated value of dc or repetitive peak positive cathode-to-anode voltage that
may be continuously applied over the standard operating temperature.
VC
Clamping Voltage: The voltage ac ross the device in a region of low differential resistance during the application of an
impulse current (IPP) for a speci fied waveform.
IPP
Peak Impulse Current: The maximum rated random recurring peak impulse current or nonrepetitive peak impulse
current that may be applied to a device. A random recurring or nonrepetitive transient current is usually due to an
external cause, and it is assumed that i ts effect will have completel y disappeared before the next transient arrives.
PPP
Peak Pulse Power. The rated random recurring peak impulse power or rated nonrepetitive peak impulse power. The
impulse power is the maximum-rated value of the product of IPP and VC.
ID
Standby Current: The current through the device at rated stand-off voltage.

NOTES: 1. Normal sel ection criteria for TVS devices is by rated stand-off volt age (VWM) and sh ould be equal or greater th an dc or continuous peak
operating voltage.
2. TVS devices are tested to maximum peak pulse current (IPP) with clamping voltage monitored. Th is surge capability is one of the most
significant electrical characteristics of the device and should be con sidered as part of customer quality inspections.
3. For Bidirectional types having VWM of 8 volts and under, the ID leakage current is doubled. Also for bidirectional parts, the capacitance
will be half that shown in Fig. 2 for zero bias.
4. For un idirectional, the forward voltage (VF) is 3.5 volts maximum at 100 Amps peak for 8.3 ms half-sine wav e.
