The device does not include power line protection (no internal crowbar or SCR structure), so it is best applied as a secondary transient suppressor on signal or DC power rails rather than a primary AC mains protector. ## Obsolete — sourcing through independent channels Littelfuse lists the 1.5KE510C as Obsolete. No pin-compatible direct replacement from Littelfuse is documented, so a board spin would be required to substitute a different TVS.","metaTitle":"Littelfuse 1.5KE510C TVS Diode, 1.5kW, DO-201","metaDescription":"Littelfuse 1.5KE510C bidirectional TVS diode, 1500W peak pulse, 434V standoff, DO-201.
