NOTE 1: A TVS is normally selected according to the rated “Standoff Voltage” V
WM
that should be equal to or greater than the dc or
continuous peak operating voltage level.
NOTE 2: Also available in military qualified types with a JAN, JANTX, or JANTXV prefix.

Definition
Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition. (See Note 1 above.)
Breakdown Voltage: This is the Breakdown Voltage the device will exhibit at 25
C
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
due to both the series resistance and thermal rise and positive temperature coefficient (
α
V(BR)
)
Peak Pulse Current: The peak current during the impulse (See Figure 2)
Peak Pulse Power: The pulse power as determined by the product of V
C
and I
PP
Standby Current: The current at the standoff voltage (V
WM
)
Breakdown Current: The current used for measuring Breakdown Voltage (V
