The P600 axial package is a through-hole device — the leads are soldered into plated-through holes on the PCB, which means it is a repair-friendly form factor for board-level rework and a straightforward pick-and-place target for production through-hole insertion equipment. ## What the clamping ratings mean for the circuit The minimum breakdown of 233 V is the threshold where the Zener enters conduction — anything below 210 V reverse standoff passes through with near-zero leakage, and only transients that exceed 233 V trigger the clamp. When a 10/1000 µs surge fires, the clamping voltage ceiling of 349.5 V is the peak voltage the protected rail sees at 14.6 A; the part absorbs the surge energy and dissipates it as heat across the Zener junction. The -55°C to 175°C junction temperature rating is wide enough for most industrial enclosures, outdoor telecom cabinets, and automotive compartments without derating concerns in ambient environments below roughly 150°C.","metaTitle":"Littelfuse 5KP210A TVS Zener Diode, 210V, 5kW","metaDescription":"Littelfuse 5KP210A unidirectional TVS Zener, 210V standoff, 5kW peak pulse, P600 axial.

The clamping voltage of 349.5 V is the peak the downstream circuitry experiences when a surge triggers breakdown at 233 V minimum; the 14.6 A peak pulse rating defines how much current the Zener conducts at that worst-case voltage for the 10/1000 µs surge shape."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/littelfuse-inc/5KP210A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/littelfuse-inc/5KP210A when reusing this data.
