P Peak Pulse Power Dissipation
-- Max power dissipation
PPM V Stand-off Voltage
-- Maximum voltage that can be applied to the TVS without operation
R V Breakdown Voltage
-- Maximum voltage that flows though the TVS at a specified test current (I )
BR

V Clamping Voltage
-- Peak voltage measured across the TVS at a specified Ippm (peak impulse current)
C I Reverse Leakage Current
-- Current measured at V
