TVS devices are not typically used for dc power dissipation and are instead operated at or less than their rated standoff voltage (V
WM
) except for
transients that briefly drive the device into avalanche breakdown (V
BR
to V

region).

Note 1: TVS devices are normally selected according to the reverse “Stand Off Voltage” (V
WM
) which should be equal to or greater than dc or
continuous peak operating voltage level.
•
For bidirectional parts, add suffix C at end of the part number.
*
The minimum breakdown voltage as shown takes into consideration the ±1 volt tolerance normally specified for power supply regulation on
most integrated circuit manufacturers data sheets. Similar devices are available with reduced clamping voltages where tighter regulated power
supply voltages are employed.
