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.
SYMBOLS & DEFINITIONS

Standoff Voltage: Applied Reverse Voltage to assure a nonconductive condition. (See Note 1
above.)

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)
)
