•Peak Pulse Power Dissipation- P_PPM
-- Max power dissipation
•Stand-off Voltage - V_R
-- Maximum voltage that can be applied to the TVS without
operation
•Breakdown Voltage - V_BR
-- Maximum current that flows though the TVS at a specified test
current (I_T)
•Clamping Voltage - V_C
-- Peak voltage measured across the suppressor at a specified
Ippm (peak impulse current)
•Reverse Leakage Current - I_R
-- Current measured at V_R
•Forward Voltage Drop for Uni-directional - V_F
