For an existing BOM line that calls out this exact part, the supply path runs through independent surplus channels. ## Clamping performance and selection The 103 A peak pulse current at the clamping voltage of 14.5 V defines the surge the diode can shunt without failing. The 8.55 V reverse standoff voltage means the diode stays in high-impedance mode on a nominal 8.5 V rail, clamping only when the line exceeds 9.5 V breakdown. A 14.5 V clamp ceiling protects downstream silicon rated for 16 V or higher. ## Package and deployment context DO-201AD axial-lead package — the through-hole body handles the 1.5 kW pulse without the thermal limitations of a smaller SMD footprint.","metaTitle":"Littelfuse 1.5KE10ARL4G TVS Diode, 1.5 kW, DO-201AD","metaDescription":"Obsolete Littelfuse 1.5KE10ARL4G Mosorb Zener TVS, 1.5 kW peak pulse, 103 A Ipp, DO-201AD axial.
