For a 150 V rail the clamping margin — the gap between standoff and the 243 V clamping ceiling — is meaningful: the downstream semiconductor must survive that ceiling during the event, so the TVS buys time for the fuse or supply to clear the fault before the protected load sees the full surge energy. ## High-temperature grade and axial thermal path The P600 axial package provides a direct thermal leg path to the PCB copper, which matters at 5 kW peak pulse — the lead-frame conductance is part of the effective RthJC, and the board-side pad must be sized accordingly for repeated surge events. ## Sourcing posture and series context Listed Active by Littelfuse, sourced through independent distribution against an RFQ. The base product number 5KP1 groups this into the standard 5KP-A unidirectional series — the HRA suffix denotes the high-reliability screening grade; the family is Littelfuse's go-to for industrial and automotive protection circuits where a single-surge 5 kW clamp is the design requirement.","metaTitle":"Littelfuse 5KP150A-HRA TVS Diode, 5kW 150V","metaDescription":"Littelfuse 5KP150A-HRA unidirectional TVS diode, 5000W peak pulse, 150V standoff, 243V clamping, P600 axial.
