The 432 V minimum breakdown voltage is the guaranteed trigger point; the 690.9 V maximum clamping voltage at 2.3 A peak pulse current defines the voltage the downstream circuitry must survive without damage. This is a through-hole part in a DO-201AA (DO-27, Axial) package. The axial leads suit point-to-point wiring or traditional PCB mounting where the body sits above the board—the 0.050-inch lead diameter fits standard 1.0 mm plated-through holes. Bulk packaging means no tape-and-reel; you are handling loose parts for manual or wave-solder assembly. ## Temperature grade and application scope The operating junction temperature range spans -55°C to 175°C, covering industrial and some automotive under-hood environments. The device has no power line protection (no internal crowbar or foldback), so it is intended for secondary-side transient suppression on signal, data, or DC power lines—not for primary AC mains surge clamping. ## Lifecycle reality for procurement Littelfuse lists the 1.5KE480C-B as obsolete. No official successor order code is recorded. The DO-201 package and 1.5KE family are widely second-sourced by other manufacturers, but pin-compatible equivalents require a cross-reference search at quote time.","metaTitle":"Littelfuse 1.5KE480C-B TVS Diode, 1.5kW, 690.9V Clamp","metaDescription":"Obsolete 1.5KE480C-B bidirectional Zener TVS from Littelfuse. 1500W peak pulse, 408V standoff, 690.9V clamp.
