V
is measured after I
has been applied for < 300ms.

SYMBOLS & DEFINITIONS
Symbol
VWM
Definition
Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition. (See Note 1.)
V(BR)
Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25oC
Maximum Clamping Voltage: The maximum peak voltage appearing across the TVS when subjected to the
peak pulse current in a one millisecond time interval. The peak pulse voltage is the combination of voltage rise
VC
due to both the series resistance and thermal rise and positive temperature coefficient (α
Peak Pulse Current: The peak current during the impulse (See Figure 2)
)
V(BR)
IPP
PPP
ID
Peak Pulse Power: The pulse power as determined by the product of VC and IPP
Standby Current: The current at the standoff voltage (VWM
)
I(BR)
Breakdown Current: The current used for measuring Breakdown Voltage (V(BR))
NOTE 1: A TVS is normally selected according to the rated “Standoff Voltage” VWM that should be equal to or greater than the dc or
continuous peak operating voltage level.
