Peak Pulse Power Dissipation -- Max power dissipation

Stand-off Voltage -- Maximum voltage that can be applied to the TVS without operation

Breakdown Voltage -- Maximum voltage that ﬂows though the TVS at a speciﬁed test current (I

)

Clamping Voltage -- Peak voltage measured across the suppressor at a speciﬁed Ippm (peak impulse current)

Reverse Leakage Current -- Current measured at V
