The 5KP-HRA sits in front of circuits that cannot tolerate a clamp above 21.5 V, so the Ipp rating confirms the part clears the fault current required to keep the clamped rail within that limit. ## Standoff and breakdown — the TVS operating band The reverse standoff voltage of 13 V sets the continuous working voltage the diode sees in normal operation — it sits off, leaking only microamps, doing nothing until a transient pushes it into avalanche. The minimum breakdown of 14.4 V is where avalanche begins; the clamping maximum of 21.5 V is the ceiling the protected load ever sees, even at full Ipp. For a board-level test engineer validating the protection loop, the key check is that the clamping voltage at the rated 237.2 A does not exceed the absolute-max input of whatever is behind it. ## Wide temperature grade and axial package The P600 axial through-hole package mounts into a board hole pattern; lead dress and board copper area under the device determine thermal resistance from junction to ambient. For a through-hole device at 5 kW peak, the board layout matters more than the housing for thermal management during a surge event.","metaTitle":"Littelfuse 5KP13CA-HRA, 5kW TVS Diode, 13V Standoff","metaDescription":"Littelfuse 5KP13CA-HRA is an axial TVS diode rated 5kW peak pulse, 237.2A peak pulse current, 13V standoff / 21.5V clamping.
