Reverse standoff voltage is 434 V; the device starts to break down at 459 V minimum. This means a 480 VAC line transient that exceeds the standoff level will be clamped before the downstream silicon sees the full surge. ## Package and temperature envelope Housed in a DO-201AA (DO-27) axial-lead package, through-hole mounted. The junction operates from -55°C to 175°C, covering industrial and telecom ambient ranges with margin for self-heating during the pulse. Littelfuse lists the 1.5KE510C-B as Obsolete.","metaTitle":"1.5KE510C-B Littelfuse Zener TVS, 1500W, 434V, DO-201","metaDescription":"Littelfuse 1.5KE510C-B Zener TVS diode, 1500W peak pulse, 434V reverse standoff, DO-201 axial.
