Parameter
Description
(1) VBR Breakdown voltage The Voltage that flows though the TVS at a specified test current (IT)
(2) IT Test current A specified test current that flows though the TVS
(3) VRM Stand-off voltage Maximum voltage that can be applied to the TVS without operation
(4) IR Leakage current @ VRM Current measured at VRM
(5) VC Clamping voltage Peak voltage measured across the suppressor at a specified IPP (peak impulse current)
(6) IPP Peak pulse current The maximum surge current that flows though the TVS
